Book Cover of Bernard Amadei

New Publications by Society Member Bernard Amadei (December 27, 2018)

Society member Dr. Bernard Amadei has announced his two forthcoming volumes, A Systems Approach to Modeling the Water-Energy-Land-Food Nexus, Volume I: Defining and Analyzing the Landscape, and A Systems Approach to Modeling the Water-Energy-Land-Food  Nexus, Volume II: System Dynamics Modeling and Dynamic Scenario Planning. The volumes are due to be released in January 2019. In a summary of the work, Bernard notes “In planning for the development and growth of any community, it must be understood that the essential elements of water, energy, food, and land resources are all inter-related in complex relationships. With the rapid urbanization and population growth worldwide, the essential elements must be carefully factored in when planning on how to successfully grow and advance communities. This two-volume set will significantly help the urban and regional planner and the associated civil and environmental engineers use the tools of systems engineering to more accurately forecast and plan for how monies and resources can be best allocated to meet those essential needs. The first of this two-volume work focuses on the methods for first analyzing and modeling the existing site and community, while the second volume provides details on using the engineering tools of system dynamics to better understand, model and plan for community development needs.”

Society members will receive a 15% discount on the purchase of both volumes (mention code AMA2019) or 10% discount for one volume (mention code AMA20192). The discount applies to purchases made before January 30, 2019; email [email protected] or call 800.632.0880.

M.S.JalaliSociety Member Mohammad Jalali’s Article Published in The Journal of Strategic Information Systems (November 12, 2018)

The article “Decision-making and biases in cybersecurity capability development: Evidence from a simulation game experiment,” by Society member Mohammad S. Jalali, along with colleagues Michael Siegel and Stuart Madnick, was recently published in The Journal of Strategic Information Systems. In the abstract, the authors explain, “We developed a simulation game to study the effectiveness of decision-makers in overcoming two complexities in building cybersecurity capabilities: potential delays in capability development; and uncertainties in predicting cyber incidents. Analyzing 1479 simulation runs, we compared the performances of a group of experienced professionals with those of an inexperienced control group. Experienced subjects did not understand the mechanisms of delays any better than inexperienced subjects; however, experienced subjects were better able to learn the need for proactive decision-making through an iterative process. Both groups exhibited similar errors when dealing with the uncertainty of cyber incidents. Our findings highlight the importance of training for decision-makers with a focus on systems thinking skills, and lay the groundwork for future research on uncovering mental biases about the complexities of cybersecurity.” Read more in the full article.

Andrew Jones photoThe New York Times Op-Ed Article by Society Member Andrew Jones (October 19, 2018)

On October 6, 2018, The New York Times published the article “Stopping Climate Change Is Hopeless. Let’s Do It.” By Society member and co-founder of the Climate Interactive, Andrew Jones and colleague Auden Schendler. The article is a call for action to address climate change beyond our “standard practices.” The authors state, “Our actions must be to scale, so while we undertake individual steps in our lives, like retrofitting light bulbs, we must realize that real progress comes from voting, running for office, marching in protest, writing letters, and uncomfortable but respectful conversations with fathers-in-law. This work must be habitual. Every day some learning and conversation. Every week a call to Congress. Every year a donation to a nonprofit advancing the cause. In other words, a practice.” Read more in the full article accessible on the website of The New York Times.


A.H.G. Saryazdi & M. Manteghi, Iran Chapter of the SDSIran Chapter Members’ Article Published in The Journal of Industrial Management (October 12, 2018)

The research article “Test and Validating the Group Model Building with the Reference Model” by Ali Haji Gholam Saryazdi and Manuchehr Manteghi, members of the System Dynamics Society's Iran Chapter, was recently published in The Journal of Industrial Management. In the abstract, the authors state "In this paper, we evaluate and compare models of group modeling sessions extracted from the project "Designing Aviation Technology Park" with the reference model derived from the literature review, by using the distance ratio approach of three levels, including the elements, the causal loops, and the full model level. As became clear from the results of this approach the MDR = 6.84 which indicates that the model as the reference model and the group models were similar. EDR and LDR values indicate between model elements and the loops level were similar. In conclusion, we can say that the model is a valid model and the resulting models are consistent with other studies in the literature.” Please read more in the full article which can be accessed here.

PLOS ONE logoSociety Members’ Article Published in PLoS ONE (October 9, 2018)

On September 27, 2018, the article “Modeling and estimating the feedback mechanisms among depression, rumination, and stressors in adolescents,” by Society members Niyousha Hosseinichimeh, Mohammad S. Jalali, Hazhir Rahmandad, along with their colleagues Andrea K. Wittenborn and Jennifer Rick, was published in PLoS ONE. As stated in the abstract, “The systemic interactions among depressive symptoms, rumination, and stress are important to understanding depression but have not yet been quantified. In this article, we present a system dynamics simulation model of depression that captures the reciprocal relationships among stressors, rumination, and depression. Building on the response styles theory, this model formalizes three interdependent mechanisms: 1) Rumination contributes to ‘keeping stressors alive’; 2) Rumination has a direct impact on depressive symptoms; and 3) Both ‘stressors kept alive’ and current depressive symptoms contribute to rumination.” The full article can be accessed here.

Sergey Navmov photoSystem Dynamics Seminar at MIT on Friday, October 5th (October 2, 2018)

As a part of an ongoing System Dynamics Seminar Series, MIT Sloan will host Society member Sergey Naumov as a guest speaker this Friday, October 5th, from 12:00-1:30 PM. Sergey will present "Unintended Consequences of Automated Vehicles and Pooling for Urban Transportation Systems." As stated in the abstract, “Automated vehicles (AVs) have emerged rapidly in recent years, becoming a focus of high expectations and heated debates. Advocates argue that the arrival of AVs will make driving safer, greener, cheaper, and faster, bringing ubiquitous access to transportation while significantly reducing traffic congestion and environmental impacts. Skeptics, in contrast, suggest that the appeal of AVs will induce additional driving, offsetting or even overwhelming the positive effects of increased automation.” For more information on this presentation as well as a full schedule of upcoming System Dynamics seminars, please visit the MIT Sloan Academic Areas Research Seminars web page: system-dynamics-seminar.

UK Chapter Announces New PhD, Society Member Dr. David Carter (September 19, 2018)

A hearty congratulations from the UK Chapter to Dr. David Carter, who was recently awarded a PhD by the University of Plymouth, UK.  Dr. Carter’s thesis is titled “Time for change: a study of enrollment decision dynamics for admission into English secondary education.” His thesis links competition for secondary school places and family responses to such challenges, to determine enrollment policies that can sustain wellbeing longer-term. The thesis abstract states that “The research makes a clear, three-way contribution to knowledge. Firstly, intrinsic case study theory is enhanced by data triangulation between induced, deduced and abduced research approaches. Secondly, the system dynamics discipline is strengthened by studying compulsory school enrollment. Finally, developing practice-based policy through multi-agency groups endorses cooperative rather than unilateral solutions, for helping change lives.” 


Dr. Rachel Freeman photoPaper by Member Rachel Freeman Published in Frontiers in Energy Systems (September 18, 2018)

Society member Dr. Rachel Freeman has published an open source paper in Frontiers in Energy Systems. Summarizing the paper, Rachel states “[the paper] links natural capital stocks with the rebound effect that exists within socio-technical systems. The paper presents a theory about how the rebound effect might look in a future world in which the supply of resources is constrained. System dynamics stock and flow diagrams are used to conceptualise the very slow and very large feedback between humanity’s use of resources and the viability of stocks of natural capital, along with stocks of human-created capital and waste. This is a sole author paper, but builds on a previous paper with co-authors that examined Jevons’ Paradox with system dynamics simulation modelling; it estimated levels of interventions that would be needed to more reliably drive down greenhouse gas emissions from road transport.” Read more in the full paper available now on the Frontiers in Energy Research website.

Mahdi Bastan photoStefan GrosserSociety Members Mahdi Bastan and Stefan Grösser Granted the 2018 IEOM Simulation and PLM Competition Award (July 30, 2018)

Society members of Mahdi Bastan and Stefan Grösser, have won the 2018 IEOM Simulation and PLM Competition award in the International Conference on Industrial Engineering and Operations Management held in Paris, France. This award was granted to the outstanding presentations on the simulation and product lifecycle management. 

They presented a paper entitled as “Analysis of Development Policies in Occupational Health and Safety Management System: A System Dynamics Approach”, which ranked on the second place in the simulation and PLM competition of IEOM conference held in IESEG Paris La Defense, July 27, 2018. 

As mentioned in the abstract of their paper, although there has been an increasingly technological progress in the societies for years, but the human health and safety have been under the shadow of many hazards. The main aim of this study was presenting a system dynamics model in order to find the dynamics available in the safety management systems, occupational health and accident management. A set of unsafe actions and conditions resulted in injuries and occupational accidents. The accidents are being reduced in rate through the identification, prevention and elimination of such unsafe circumstances. In order to manage such a system efficiently, there is a substantial need to assess the development policies by a DSS model. The full paper can be found in the conference proceeding.

Iran Chapter Members’ Article Published in The International Journal of Quality & Reliability Management (July 17, 2018)

The research article “Waste management in a wire and cable company through system dynamics approach” by Society members Ali Haji Gholam Saryazdi and Mohammad Ghavidel, was recently published in The International Journal of Quality & Reliability Management. In the abstract, the authors state, “Producing high quality products and free of defects is considered as strategic objectives that help each organization to achieve proper share in the competitive market. However, the reduction and elimination of waste materials plays an important role in achieving this goal. On the other hand, one of the most important issues in any industry is the reduction of product cost among which waste is one of the most important factors. This paper tries to investigate into dynamics of waste production in the product structure of a wire and cable manufacturing company that deals with a high volume waste. For the first step, the elements and structure of the waste produced in Wire and Cable Company have been studied through system dynamics approach. Then the achieved model has been simulated in order to provide appropriate solutions to control the amount of waste.” Read more in the full article available on the website.


Greenwood logoGreenwood Strategic Advisors Releases “Mind the Gap” Report (July 16, 2018)

Greenwood Strategic Advisors has announced the release of a new report titled “Mind the Gap—Funding and Financing City Investments in the 21st Century.” The report contains analysis from the Greater London Simulator model that Greenwood had developed in partnership with the Mayor’s Office. From the summary detailed on their website: “‘Mind the Gap’ is a report about Greater London as an urban system, how it responds to public investments, and the long-term socioeconomic ‘cost of not’ making such investments. The analyses in this report address a critical investment gap, its consequences and potential solutions for Greater London. The gap is caused by chronic shortages of public funding and financing for city investments. These shortages delay or prevent public investments, causing permanent losses of future housing availability, environmental quality, social balance, economic growth, and government revenues.” The full report can be accessed on the website of Greenwood Strategic Advisors.

Paulo GoncalvesMember Paulo Gonçalves' Article in European Journal of Operational Research (July 3, 2018)

The article “Short-term Bias and Strategic Misalignment in Operational Solutions: Perceptions, Tendencies, and Traps,” by Society member Paulo Gonçalves, and colleagues Rick Hardcopf, Kevin Linderman, and Elliot Bendoly, was published in the European Journal of Operational Research last year. In the abstract, the authors state “In this study, we use a multi-method approach to examine the following questions: when faced with explicit profit gaps, does a firm's strategic orientation influence manager perceptions regarding the ability of various tactical options to resolve the gap, do managers feel pressure to pursue certain tactical options over others, and what implications do tactical mismatches with strategy have for long-term gap resolution? As part of the research process, we build a grounded systems model (using grounded theory and Systems Dynamics techniques) which attempts to capture how tactical changes, in combination with the firm's competitive strategy, can ostensibly impact a firm's profit gap over time.” Read more in the full article accessible on the Science Direct website.

Gary Linneusson photo 2018Society Member Gary Linnéusson Defended his PhD Dissertation (June 26, 2018)

In April 2018, the PhD dissertation “Towards Strategic Development of Maintenance and its effects on Production Performance: A hybrid simulation-based optimization framework” by Society member Gary Linnéusson was successfully defended under the supervision of Prof. Amos H.C. Ng and Dr. Tehseen Aslam at University of Skövde in Sweden.

Maintenance performance of machine equipment in production systems are the result of a set of historical choices and activities, forming the basis for production performance. The research has investigated how the balance between reactive and proactive work can be analyzed using System Dynamics (SD) supported by the application of multi-objective optimization (MOO). Based on a SD model of maintenance behavior, published in IJPE, further work applied MOO to support a more knowledge-driven development of maintenance work based on its effects on the production system. Finally, an innovative hybrid framework was proposed consisting of several phases. At-large involving SD+MOO analyses, in order to select the most desired tradeoff-optimal solution between conflicting objectives, studying its underlying SD model behavior, and link key output parameters with a commercial discrete-event simulation (DES) software having MOO integrated, defining the ranges of the searched decision space resulting in pinpointed activities to generate maintenance driven improvements. The full text can be accessed from DiVA.  On behalf of the Society, congratulations to Dr. Linnéusson!

Article by Society Member Takuro Uehara Published in Sustainability (June 4, 2018)

The article “Fully Dynamics Input-Output/System Dynamics Modeling for Ecological-Economic System Analysis,” by Society member Takuro Uehara and colleagues Mateo Cordier and Bertrand Hamaide, was published in the journal Sustainability. In the abstract, the authors state “The complexity of ecological-economic systems significantly reduces our ability to investigate their behavior and propose policies aimed at various environmental and/or economic objectives. Following recent suggestions for integrating nonlinear dynamic modeling with input-output (IO) modeling, we develop a fully dynamic ecological-economic model by integrating IO with system dynamics (SD) for better capturing critical attributes of ecological-economic systems.” To access the full article, please visit the publisher’s website.

Jorge Queiroz photoNew Book by Society Member Jorge Queiroz (May 24, 2018)

The Brazilian edition of the book titled Corruption, Evil of the Century / Corrupcao, O Mal do Seculo (Alta Books) written in Norway by Society member Jorge W de Queiroz (MSc., University of Bergen), is now available for pre-sale. In the book, Jorge uses the System Dynamics methodology in a pioneering and novel fashion. Foreword and presentation are written by renowned professors Monica de Bolle of John Hopkins University and Peterson Institute for International Economics, and Roberto Troster of Pontifical Catholic University of Sao Paulo and University of Sao Paulo. Comments are by Manoel Justino, Supreme Court Judge, Sao Paulo, and the fourth cover is by journalist Lucia Sweet.

book coverThe book summary description reads: ‘Grand Corruption’ is unquestionably the Evil of the Century, the worst crime perpetrated against societies and origin of all other evils, including wars – a global epidemic that hides behind sophisticated and obscure schemes, transnationally interconnected, reaching unprecedented levels, never seen in history.
The author demonstrates that its solution in an effective and enduring manner is possible, but that for this to happen, it is vital that the society as a whole first understands how the process and its complex dynamics take place. Treating the symptoms without understanding this chronic ‘illness’ that contaminated the State will not cure such disease in a well-founded and lasting manner.
It is the author’s conviction is that we can only study the different solutions to this chronic problem (i) from the moment we understand it clearly, how it is formed, which agents are involved, and the existing destructive and constructive dynamics, (ii) and by adopting a holistic, systemic thinking - not by treating it separately, in an isolated form.”

New Publication by Members David Lane and John Sterman (May 21, 2018)

The article “A model simulator: The lives of Jay W Forrester,” by Society members David C. Lane and John D. Sterman, was recently published in the Journal of Simulation. In the abstract, the authors wrote “Forrester’s presence as one of the 23 members of the IFORS “Operational Research Hall of Fame” rests on his creation, development and application of the System Dynamics approach. However, his career also involved highly significant theoretical and applied work in, and contributions to: servomechanisms, computer memory, digital computing technology, flight simulators and defence information systems. Rich and varied as these experiences were, they involve a consistency and commonality of interests and approach. The paper outlines Forrester’s life and how his background and early careers led to the creation of System Dynamics.” To access the full article, please visit the website of Taylor & Francis Online.

John Sterman photographArticle by Member John Sterman in The New York Times (May 4, 2018)

The op-ed article “Pruitt Is Wrong on Burning Forests for Energy,” by Society member John Sterman, with colleagues William H. Schlesinger, Beverly Law, and William R. Moomaw, was published yesterday by The New York Times. The article presents scientific facts that contradict E.P.A. administrator Scott Pruitt’s declaration last month that burning wood for energy production was carbon neutral. With growing concern, the authors join a team of scientists to challenge the inaccuracies supporting the policy change. The authors explain, “It’s basic science. The simple fact is that cutting and burning trees adds carbon dioxide to the atmosphere, trapping radiant heat from the earth and making the planet warmer. … Moreover, throughout the many decades before the replacement forests can grow enough to remove the extra carbon dioxide from the atmosphere, the previously added gas will thaw more permafrost and melt more ice, make ocean acidification worse, accelerate global warming, speed sea-level rise, increase the incidence of extreme weather, worsen drought and water stress, and hurt crop yields — effects that will persist for centuries or longer.” Read more in the full article available on the NYT website.

John Sterman photographMember John Sterman Quoted in Recent Article (May 3, 2018)

The article “Canada’s other contentious energy export sees strong growth potential,” by Ian Bickis of the Canadian Press, references a paper published by Society member John Sterman. The article discusses Canada’s energy export, the wood pellet, and environmental concerns associated with its use. In his paper, John reveals the inefficiency of burning pellets as it would, in the short term, release more carbon dioxide than coal. During an interview, John said "The next few decades, the rest of this century, this is the critical period. Biofuels, and especially wood pellets, actually worsen climate change over this period."

The book Systems Education for a Sustainable Planet, co-edited by Society member Bob Cavana and colleague Ockie Bosch, has been published by MDPI. The book is based on the Special Issue of the international journal Systems on “Systems Education for a Sustainable Planet.” It features a collection of papers addressing important systems education and sustainability issues, and many of the contributions have been provided by highly respected members of the System Dynamics Society. As stated in the preface, “…The capacity to conceptualise and redesign, in systems and sustainability terms, will increasingly be what society and employers require. This “requirement” is globally one of the biggest challenges for education. Educators have to ensure they meet the growing need for graduates, from all areas of interest, who not only have an understanding of how they fit into societal and global systems, but also know how to operate in an environment where humanity is exceeding planetary limits. Systems thinking and dynamic approaches offer a holistic and integrative way to assess the major dimensions of complex problems. Together, they contribute needed skills and knowledge to help achieve the attributes industry wants from future graduates.” Systems Education for a Sustainable Plant is available now on the website of the publisher.

Four articles by Society member Guido Noto have been added to the Society's Bibliographic Updates web page this month. The papers were published in the following journals: European Management ReviewSystems Research & Behavioral Science, Public Organization Review, and Long Range Planning. Guido notes "These papers are mainly focused on the opportunities provided by the combination of SD modelling with Strategic and Performance Management frameworks both in the private and in the public sector. Particularly, the paper “Applying System Dynamics Modelling to Strategic Management: A Literature Review” discusses the theoretical and empirical development of SD in the Strategic Management field. The other studies, such as “A dynamic business modelling approach to design and experiment new business venture strategies,” focus on the potential benefits of supporting strategy tools (e.g. Business Model, Strategic Planning) with system analysis and simulation so as to support decision-making processes at various levels." 


System Dynamics Review coverSystem Dynamics Review Early View (April 19, 2018)

The research article “Supply constraints and waitlists in new product diffusion,” by Society members David Keith, John Sterman, and Jeroen Struben, is featured in the Early View of the System Dynamics Review. In the abstract, the authors state: “Constraints on production capacity adjustment present a strategic and operational problem for managers launching products when demand is uncertain. Stock‐outs can be costly if demand exceeds available product supply, as sales are deferred or lost when prospective customers are waitlisted. …We develop a generalized model of new product diffusion under supply constraints that explicitly accounts for endogenous customer waitlisting and waitlist‐generated word‐of‐mouth.” Also included in the Early View is the Notes and Insights article “On the growth of the system dynamics field,” by Society members Jack Homer and George Richardson. Both articles are now available on the Wiley Online Library and will later be published in an issue of the System Dynamics Review.

The article “Integrating Qualitative and Quantitative Methods in Participatory Modeling to Elicit Behavioral Drivers in Environmental Dilemmas: the Case of Air Pollution in Talca, Chile,” by Policy Council member Nuno Videira and colleague Franziska Meinherz, was published in the journal Environmental Management. In the abstract, the authors describe “The aim of this paper is to contribute to the exploration of environmental modeling methods based on the elicitation of stakeholders’ mental models. This aim is motivated by the necessity to understand the dilemmas and behavioral rationales of individuals for supporting the management of environmental problems. The methodology developed for this paper integrates qualitative and quantitative methods by deploying focus groups for the elicitation of the behavioral rationales of the target population, and grounded theory to code the information gained in the focus groups and to guide the development of a dynamic simulation model. The approach is applied to a case of urban air pollution caused by residential heating with wood in central Chile.” The full paper can be accessed on the Springer Link website.

BSIG Webinar on April 19, with Society Member Ken Cooper (April 13, 2018)

Join hosts Seth Cordes and Raafat Zaini for the latest Business SIG webinar: Simulation based pharma research - The next frontier with guest Ken Cooper, System Dynamics Society Vice President of Professional Practice. The webinar will run on Thursday, April 19, 2018, from 12:00 PM to 1:00 PM EDT (GMT-4). Please share the invitation and bring your questions to be answered LIVE on Youtube:

Ken Cooper has led hundreds of applications of System Dynamics modeling over four decades. While leading Pugh-Roberts Associates for over 20 years, Ken pioneered the development of project management modeling, dispute resolution with SD, and led corporate strategy work for senior clients in several industries, including aerospace, automobiles, banking, bioscience, construction, shipbuilding, and telecommunications. Ken is a two-time Edelman Laureate for his modeling work and won the Society's Applications Award in 2010. In 2011, Ken turned his focus to human biology, following a lifelong dream to apply System Dynamics modeling to understanding and curing the most complex diseases of the body. This work led to the first clinical trial ever approved based on analyses from a computer simulation model. Ken has led the development of models of the human immune system, HIV, type 1 diabetes, cancer, and chronic traumatic encephalopathy.

Ken explains, "Pharmaceutical research is universally acknowledged to be “too costly” (over $2 billion per new drug), “too long” (over a decade to market), and “too ineffective” (one in thousands of candidates make it). A big impediment to progress is the routine focus on narrow “silos” of research, largely ignoring the systems in which human diseases interact with the body. What if you could speed research by simulating long-term chronic systemic conditions in minutes, testing leverage points and combinations of interventions to identify the most likely successful therapies in advance of conventional (expensive) trials? Today, preclinical testing is on mice, pigs, monkeys…and the findings rarely translate well to humans. SD simulation offers important new opportunities to enhance our understanding of the systems of the body, and to identify far more effectively better treatments, even cures, for the most devastating diseases." Additional webinar program details and more information about Ken Cooper can be found on the BSIG website.

Krishna Pendyala at March for Our Lives 2018Society Sponsor Krishna Pendyala: Tackling Gun Violence with a Systems Thinking Approach (April 11, 2018)

The article “March for Our Lives: Gun Violence, Taking Sides, Limiting Choices - Blowing our Chances,” by Society Sponsor Krishna Pendyala, was featured on the Thrive Global website last week. Krishna, who has been exploring the topic of guns in schools, traveled to Washington DC with his high school-aged daughter to participate in March for Our Lives. In the article, Krishna shares his perspective on the causes of violence and what can be done to solve the problem. He states, “I cannot think of a more pressing problem gripping our nation than the number of lives lost due to gun violence, where our lack of a Systems Thinking mindset is crippling our ability to effectively address the issue. The annual death toll due to gun violence, from suicides to homicides and mass shootings, is simply staggering.” Read more about Krishna’s thoughts in the full article.


Recent Publications by Society Members Mauricio Uriona and Lucia Baur (April 10, 2018)

The article “Diffusion of photovoltaic technology in Germany: A sustainable success or an illusion driven by guaranteed feed-in tariffs?” by Society members Mauricio Uriona and Lucia Baur, was published in the May 2018 issue of Energy. In the abstract, the authors explain, “This article uses the methodology of System Dynamics to develop a model of the German photovoltaic market for small plants on private houses and tests public policies. Amongst them are different scenarios regarding the reduction or even removal of the feed-in tariff scheme in Germany. The results can improve German public policies in the field of photovoltaic technology diffusion and serve as an example for other countries and other renewable energy diffusion cases.” The full article can be accessed on the Science Direct website.

Mauricio also had work published recently in the journal Science and Public Policy. His article, “Innovation System Policy Analysis through System Dynamics Modelling: A Systematic Review,”  was co-authored Sara S. (Saartjie) Grobbelaar. In the abstract, the authors state “…we conduct a systematic literature review of past system dynamics (SD) simulation models of innovation systems (IS). By systematically reviewing fifty-four studies we present the current state-of-the-art of SD modelling applications in the IS domain.” The full article is accessible on the publisher’s website.

Ghana News LogoSystem Dynamics Used in Experiment to Break Cycle of Poverty (April 5, 2018)

The article “Using System Dynamics to Disrupt Nonprofits and Help Children in Poverty,” published on the website of News Ghana, explores the work of MIT alumnus Chris Penny. Chris is the founder and President of Broken Crayons, an organization that seeks to empower mothers therefore positively impacting their children. Chris describes the approach used in Ghana, “The first step involved Systems Dynamics, which taught me to model the relationships in all parts of a system and how those relationships influence the behavior of the system over time. Applying this knowledge, I built models to identify the root cause of youths and poverty. The overarching question centered on how I could use simultaneous interventions to break the system of poverty.” Broken Crayons conducted a successful experiment which set up businesses for a selected group of mothers with at-risk children. As stated in the article, “The experiment was a success. Today, almost all the women have tripled their income, and their children are in school. They have become self-sustaining business owners, who no longer need funding from Broken Crayons. In fact, most of them are now helping the next group of women as mentors.” Read more in the full article.

From Virginia Tech: Assistant Professor Navid Ghaffarzadegan, Graduate Research Assistant Sarah Mostafavi, and Postdoctoral Researcher Ran Xu.Members’ Article Published in System Dynamics Review Early View (March 21, 2018)

The article “Dell's SupportAssist customer adoption model: enhancing the next generation of data‐intensive support services,” by Society members Navid Ghaffarzadegan and Sarah Mostafavi, along with colleagues Armin A. Rad, Ran Xu, Sam E. Middlebrooks, Michael Shepherd, Landon Chambers, and Todd Boyum, was recently published in the Early View of the System Dynamics Review. In the abstract, the authors explain, “We developed a decision support system to model, analyze, and improve market adoption of Dell's SupportAssist program. SupportAssist is a proactive and preventive support service capability that can monitor system operations data from all connected Dell devices around the world and predict impending failures in those devices. Performance of such data‐intensive services is highly interconnected with market adoption: service performance depends on the richness of the customer database, which is influenced by customer adoption that in turn depends on customer satisfaction and service performance—a reinforcing feedback loop. We developed the SupportAssist adoption model (SAAM). SAAM utilizes various data sources and modeling techniques, particularly system dynamics, to analyze market response under different strategies. Dell anticipates improving market adoption of SupportAssist and revenue from support services, as results of using this analytical tool.” An Early View of the full article is accessible now on the Wiley Online Library and will later be included in an issue of the System Dynamics Review.

Journal of Cleaner Production cover Member Amin Dehdarian's Article Published in the Journal of Cleaner Production (March 19, 2018)

The research article, “Scenario-based System Dynamics modeling for the cost recovery of new energy technology deployment: the case of smart metering roll-out", by Society member Amin Dehdarian, was recently published in the Journal of Cleaner Production. Amin has recently finished his PhD in Management of Technology at Ecole Polytechnique Federale Lausanne (EPFL) in Switzerland. In the abstract, the author states that “…By taking a dynamic modeling approach and using System Dynamics models, this study examines the dynamics of interaction between different actors in the technology deployment process, and proposes scenarios for an efficient cost recovery. It is claimed that a dynamic view to the common Cost-Benefit Analysis approach has three advantages. First, the possibility of including actors benefiting from positive externalities or actors that can contribute to system efficiency is provided. Second, a balance can be found between the short term and long term consequences of system interventions; and finally, the development of innovative solutions, in the forms of business and policy scenarios is facilitated.” The full text can be accessed on the ScienceDirect website.

In August 2017, the PhD dissertation, “Three Essays on Methodologies for Dynamic Modeling of Emerging Socio-technical Systems The Case of Smart Grid Development,” by Society member Amin Dehdarian was successfully defended under the supervision of Prof. Christopher Tucci in the College of Management of Technology at Ecole Polytechnique Federale Lausanne (EPFL) in Switzerland. Based on the abstract, “…This dissertation develops methodologies for investigating some complex questions arising in the pre-development phase, by focusing on the case of smart grid development. The first essay uses insights from modeling interventions in complex systems and builds a System Dynamics model to investigate the cost allocation problem of smart metering roll-out. The second essay takes ideas from Technological Innovation System approach and develops a method to analyze the emergence of spatial diversity in smart grid development by combining Social Network Analysis and Agent-Based Modeling. The third essay builds on ideas from network theory and evolutionary modeling to develop a method for identifying the main path of knowledge development and analyzing knowledge trajectories in smart grid initiatives.” The full text can be accessed on the EPFL Scientific Publications website.

Logo for UNSW CanberraThe 2nd Systems Modelling Conference, October 4, 2018, UNSW Canberra, Australia (March 12, 2018)

Researchers and practitioners from systems thinking, systems modelling, and in particular System Dynamics areas, are invited to submit papers and abstracts to the 2nd Systems Modelling Conference 2018. The conference will be held at the University of New South Wales (UNSW Canberra) at the Australian Defence Force Academy. Systems thinking and modelling is the science of integration, where every system is conceptualized as a set of inter-related components. Systems thinking and modelling enables researchers to answer several questions, such as how an assumedly pure-technical/infrastructural system co-evolves with the society and economy, how a system can result in unexpected behaviors in long-term, and how we should be prepared to deal with unexpected surprises and shocks. The Capability Systems Centre at UNSW Canberra presents a one-day conference on the use of whole-systems approaches to design and manage complex problems in socio-technical and socio-ecological systems. The scheduled keynote speakers are Professor Ana Deletic, Pro Vice-Chancellor (Research), UNSW Australia and Professor Brett Bryan, Professor of Global Change, Environment and Society, Deakin University.
Submissions of extended abstracts or full papers must be emailed in PDF format to [email protected] by April 16, 2018. Please visit the conference website for information on submissions, details on the conference program, and to register.

An article by Society Member Hamilton Carvalho was featured today on the website Poder360. In a note to the Society, Hamilton states “I have been writing articles for a major journalistic site in Brazil (since last year), using System Dynamics concepts and, in some cases, causal loop diagrams to analyze public policies in the country. Today's article analyzed the recent federal intervention in the state of Rio de Janeiro. I show, with the aid of a CLD, that it only addresses symptoms instead of root causes. I attribute my inspiration to use System Dynamics in texts to popular media outlets both to the groundbreaking work of Donella Meadows and to an SDS presidential speech made by Mike Radzicki, in which he exhorted this kind of action to help in the process of disseminating System Dynamics.” Read more in the full article (printed in Portuguese) available on Poder360.

Chapter News from South Korea (March 5, 2018)

 Every year since 2000, the Korean Chapter of the System Dynamics Society holds winter and summer conferences. The 2018 annual winter conference was held on February 25, 2018 at Korea University featuring keynote speech "System Dynamics, the 32 year's Research Life,"  by Dr. Young-pyo Kim, chair-professor of Chonbuk National University. In this conference, there were seven presentations and one poster presentation. In his closing speech, Benjamin, the president of Korean Chapter, stressed the membership renewal of System Dynamics Society and participation of ISDC in Iceland, hoping some presenters will attend the ISDC in Iceland. Winter conference photos, courtesy of professional photographer, Tae Hyun Cho, can be seen at

 Professor Nam-Hee Choi of Korea National University of Transportation and Professor Jinhyung Chon of Korea University were selected as a research team on the General Collaborative Research Support Projects of the Korea Research Foundation. The research title is “Simulation Modeling for Distribution Pattern Analysis of Social-Economic-Ecological System according to Four Major River Project and Enhancing Resilience.” This research received a grant of nearly $93,000 from the Government, which is the biggest research project based on System Dynamics ever in Korea. The collaborative research team will attempt to understand the social-economic-ecological problems caused by the large-scale national projects such as the Four Major River Project, which was driven by former President of Korea and became a very controversial issue, and to suggest policy direction through simulation modeling. Also, this research can act as a climate change simulator, based on the integrated system of all variables centered on Four Major River Project, including uncertainties, climate change, social-economic-ecological systems, and resilience. This research is expected to provide insights to various researchers as leading research to solve the sustainability of the environment and the conflict structure problem of a human society that can occur at the national level beyond the regional level.

Member Josephine Kaviti Musango’s Article Published on TimesLIVE (March 2, 2018)

The article “Cape Town’s plans for what happens after Day Zero just won’t work - Here’s why,” by Society member Josephine Kaviti Musango along with her Stellenbosch University colleague, Paul K. Currie, was published on TimesLIVE (South Africa's second-biggest news website). The article explores the feasibility of the city’s disaster management strategy for Day Zero, the projected point where municipality shuts off Cape Town’s water distribution system. Using System Dynamics modeling, Josephine and Paul simulated water collection over a 24 hour period. They state, “Our findings suggest that the city’s best technical intervention would be to double the number of distribution points to 400. This would save time and ensure that Cape Town’s whole population can be serviced. Another, perhaps more practical approach, would be to keep 200 distribution points but increase the number of taps and the water pressure at each of them.” Read the details of their work in the full article.

Rana Azghandi photoMember Rana Azghandi Featured in Northeastern News (February 24, 2018)

Society member Rana Azghandi was among three PhD students featured in the [email protected] article “From ‘Gut Brains’ to Supply Chains, PhD Students Tackle Complex Problems,” by Allie Nicodemo. The article describes Rana’s research on pharmaceutical supply chains. In collaboration with her advisor, Prof. Jacqueline Griffin, and Dr. Mohammad Jalali, Rani's work looks to solutions preventing drug shortages. Exogenous shocks (recalls, production shutdowns) can lead to a shortage and the specific response is “important to maintaining a robust supply chain,” according to the article. “It’s best to look at the behavior of the supply chain to see how it will react to exogenous shocks, and evaluate static and adaptive policies based on those observations,” Azghandi said.

david c. lane photographSociety Member David Lane Contributes to UK Government Report (February 22, 2018)

A review of the United Kingdom computational modelling capabilities, Computational Modelling: technological futures, was recently published by the Government Office for Science and the Council for Science and Technology. Society member, David Lane, was one of the experts who contributed to the report. According to David, the following pages may be of interest to system dynamicists: pages 20-22, 32, 42, 64-64 and 29-30 (participative modelling). In an article about the report released by Henley Business School, Prof. Lane is quoted, “We offer some ideas about the future of modelling, for example, that, in order to support strategic thinking, senior decision-makers will themselves increasingly participate in building and using models– an area which is one of my particular interests.” 
The release of the report was also covered by the Operational Research Society. The ORS article gives the following description of the report: “The report highlights, rightly in the view of the ORS, the increasing opportunity for modelling to support better decision making.  This follows from the rapid growth in computing power, the explosion in available data, and the greater ability of models to tackle extremely complex systems.  For example, Operational Research (OR) professionals are now able to solve high value, large scaleoptimisation problems that were impossible to solve before.”

Beer Game in Real Life: Boom and Bust in the Hops Industry (February 19, 2018)

board game photo

A recent Forbes article, “Hop Vendors Swallow A Bitter Pill As They Confront An Oversaturated Market & Customers Who Can't Pay” written by Tara Nurin, recounts the effects of what errors in forecasting do to production distribution. The article explains, “…thousands of craft brewers, who, panicking after a severe U.S. hop shortage that lasted from 2013-15, ordered well over a million excess pounds of the crop they’ve since discovered they don’t need and can’t necessarily pay for. The massive imbalance between what growers harvested in the fall of 2017 and what brewers can use has already caused one hop broker to file for Chapter 11 protection and threatens to upend brewers who got caught off guard by the glut they helped create.” As John Sterman noted when sharing this article, “The beer game in real life: Endogenous hoarding of hops led to a glut. Key insight is recognizing the endogenous cause of the problem…” Read more in the full article. Think you can do better?

photo of Allen BoorsteinIn Memoriam
(February 13, 2018)

Long-term Society member Allen Boorstein died on February 12th, in New York City. Allen was a past Policy Council Member and has been an enthusiastic member and loyal sponsor of the System Dynamics Society and our conferences since 1998. Allen was instrumental in securing the conference venue in New York City in 2003. He attended most of our conferences and made a point of being present at the PhD Colloquium events held the day before the conference. The Dana Meadows Award, first given in 2001 was generously funded by Jane and Allen Boorstein until 2004 when, on Allen's urging, we created an endowment fund. Thanks to a successful fund drive, promoted and contributed to by Allen and Jane, the Dana Meadows Award will be given in perpetuity. We owe much of this success to Allen.

John Morecroft wrote “Allen was such an avid and loyal supporter of System Dynamics over so many years. He (and his wife Jane) attended nearly all our SD conferences, injecting his humour and his deep grasp of business enterprise into our deliberations.” A note from John Sterman “As you know, Allen was pretty hard of hearing the last few years but still so full of life, and still working to excite people about System Dynamics.” Peter Milling stated "A System Dynamics conference without Allen--this is hard to imagine. His wisdom and friendliness will be painfully missed." Roberta Spencer remembers Allen fondly. “Allen was so enthusiastic about System Dynamics and especially students. He never stopped learning.” To his final days, Allen was working on a book detailing the importance of System Dynamics in primary and secondary education.

Allen’s obituary is in the New York Times. He will be missed.


Ali Mashayekhi’s Lifetime Achievement Award Acceptance Speech (February 13, 2018)

At the 2017 Cambridge Conference, Professor Ali Mashayekhi accepted the System Dynamics Society’s Lifetime Achievement Award. Prof. Mashayekhi is the 5th person to receive this award recognizing those who make a significant contribution to the field over an extended period. Society member Raafat Zaini captured a portion of Prof. Mashayekhi’s acceptance speech in a live Twitter feed. Raafat wrote to the Society, describing “When Ali Mashayekhi’s speech started I asked myself wouldn’t be nice if people can follow along as it is happening right now? I hit the live button on Twitter and boom it went live.” Raafat noticed the increased following as the video was shared by many. A link to his video was also posted by a friend on Telegram, a popular social media outlet in Iran, spreading access to the speech to more students in Iran.

Many of Prof. Mashayekhi’s students were in attendance for the presentation of the Lifetime Achievement Award. We have collected quotes from a few of his former students that illustrate the impact Prof. Mashayekhi has had on them.

 I have always been impressed by Ali's impact on a generation of Iranian experts in system dynamics and policy analysis and wondered how he achieved this; his speech provided the coherent narrative of how he has masterfully used every opportunity to build effective institutions that enabled such impact. - Hazhir Rahmandad

That evening, I saw Ali as a noble man telling the story of his journey through his accomplishments. He truly opened my eyes on things that were always hidden. He has always been my hero for the way he thinks, he behaves, and he achieves. Ali Mashayekhi means a lot to me; he is my role model. There are no words that can express how thankful I am for things he has done for me. - Babak Bahaddin

It is difficult to articulate what makes one an exemplary educational leader. It definitely goes beyond intelligence and expertise in one or more scientific fields. It is about the strong sense of belief in your students, and hope in the future. It is about inspiring the new generation by reminding them about their potential and equipping them with strong analytical skills. It is about promoting evidence-based decisions and deep thinking. It is about devotion to public service through educational entrepreneurship and capacity building. And it is about true sensitivity to societal problems. Ali Mashayekhi is an exemplary educational leader, and I am thankful for his great impact on my life. - Navid Ghaffarzadegan

The full video of Ali Mashayekhi’s acceptance speech is now available on the Society’s YouTube channel. This video and other recorded conference sessions (coming soon) were filmed by our video production sponsor, Uncommon Catalyst and the Business SIG.

System Dynamics Experts to Bring Systems Simulation Modeling to Icelandic Educators and Students at the 2018 ISDC (February 12, 2018)

Icelandic teachers will have the opportunity to learn more about systems thinking and about teaching the topic of System Dynamics from international experts visiting Iceland in August 2018 for the International System Dynamics Conference being held In Reykjavík. Systems thinking is a growing and dynamic approach in pre-college education throughout the world, including the United States, Netherlands, China, Japan, and many other locations.

Conference Program Chair Robert Eberlein said, “Our goal is to encourage Icelandic educators to consider systems thinking and to participate in the 2018 System Dynamics Society conference as attendees at a workshop or roundtable session. We are fortunate this year to have our conference in Reykjavík, where we expect to have experts of international renown sharing their research and theories.”

The workshops and roundtables that are most likely to appeal to educators of students from age 4 to age 20 focus on building simulation models to study complex systemic problems. Examples of systemic problems globally include: the ice is melting; new treatments for kidney disease are improving quality of life; tensions are continuing to build in the Middle East and in North Korea; potable water is becoming scarce in parts of Africa; and the opioid epidemic is a serious problem in the United States. Systems thinking helps students to look at systemic problems more holistically as part of their curriculum and to learn to think differently about how the world works.

New Climate Interactive Report: Multisolving at the Intersection of Health and Climate (February 8, 2018)

A new report from the Climate Interactive, Multisolving at the Intersection of Health and Climate, which was supported by a grant from the Robert Wood Johnson Foundation, shares ten case studies of how people around the world created health benefits while reducing greenhouse gas emissions, often increasing social equity and saving money. Climate Interactive Co-Director Beth Sawin, lead author of the report, explains “Some solutions to protect the climate may be hiding in plain sight, such as programs to encourage walking or cycling, bring vegetation into the city, or save money for a hospital. The joy, sense of wellbeing, vitality, and financial benefit that these projects can bring provide huge motivations to action, even before people think about protecting the global climate.” The Climate Interactive will host a webinar about the report on February 14, 2018, at 9 AM (EST). The full report can be accessed on the Climate Interactive website.

MIT SDM Systems Thinking Webinar Series (February 7, 2018)

MIT Hosts System Dynamics Seminar on February 16th (February 7, 2018)

The MIT Sloan School of Management will be hosting a System Dynamics Seminar on Friday, February 16th from 12:00-1:30 PM in the Jay W. Forrester conference room (E62-450). The guest speaker will be Society member Peter Hovmand (WUSTL) presenting Understanding Structural Violence in Communities. As stated in the abstract of the presentation, "...While public health, preventive medicine, health care, community psychology, and social work have all recognized, to varying degrees, the importance of addressing structural violence (e.g., Galtung, 1969; Gilligan, 1997), there are comparatively few tools available to map the systems underlying structural violence and design dynamic community prevention and response systems. Drawing on ten years of work in both domestic and international settings, this talk illustrates the application of community-based system dynamics for addressing structural violence. Examples will draw mainly from the study of structural violence against women including sexual assault and intimate partner violence." Lunch will be provided at the seminar. Please visit for more information about all of the research seminars happening this semester.

COs exhaust from smoke stackSociety Members Contribute Article in Environmental Research Letters (January 19, 2018)

A new research paper, “Does replacing coal with wood lower CO2 emissions? Dynamic lifecycle analysis of wood bioenergy,” by Society members John Sterman (Jay W. Forrester Professor of Management at MIT Sloan School of Management) and Juliette Rooney-Varga (Director of the UMass Lowell Climate Change Initiative) and their colleague Lori Siegel (PhD, Senior Modeler for Climate Interactive) explores whether biofuels actually reduce greenhouse gas (GHG) emissions. The abstract states, “The European Union declared biofuels to be carbon-neutral, triggering a surge in wood use. But do biofuels actually reduce emissions? ...Because combustion and processing efficiencies for wood are less than coal, the immediate impact of substituting wood for coal is an increase in atmospheric CO2 relative to coal.” The article can be found in the academic journal Environmental Research Letters.

News From the Korea Chapter of the System Dynamics Society (January 5, 2018)

There is a meaningful initiative in Korea concerning System Dynamics/Systems Thinking in K-12 education including classroom curriculum and school management. A group of teachers, vice principals, principals, and public officials of the Office of Education have studied complexity theory for ten years to address problems which are encountered every day in school caused by the increase of complexity. Recently, they were introduced to System Dynamics and the Korea Chapter of System Dynamics Society sponsored their learning, initiated by Dr. Chung, president of Korean Chapter System Dynamics Society. This group was very touched by the lessons of SD/ST and made a decision to translate Peter Senge’s Schools That Learn, A Fifth Discipline Resource. Dr. Chung, also a member of the translation team, has reported that the translation was completed on the last day of the year 2017, and is now waiting for publisher's process.


Members’ Article in Nature Climate Change (January 4, 2018)

The article “Linking models of human behavior and climate alters projected climate change,” by Society member Sara Metcalf, Travis Franck, and Asim Zia, along with colleagues Brian Beckage, Louis Gross, Katherine Lacasse, Eric Carr, Jonathan Winter, Peter Howe, Nina Fefferman, Ann Kinzig, and Forrest Hoffman, was published in Nature Climate Change. The analysis in the article used the Climate Interactive/MIT C-ROADS model. As described in the abstract, “Although not considered in climate models, perceived risk stemming from extreme climate events may induce behavioural changes that alter greenhouse gas emissions. Here, we link the C-ROADS climate model to a social model of behavioural change to examine how interactions between perceived risk and emissions behaviour influence projected climate change.” The full article can be accessed on the publisher’s website.
