SD Movie Night: Group Model Building video this week at UAlbany

You are invited to this semester’s SD Movie Night, showing Forrester’s Seminar Series on System Dynamics, at the University at Albany School of Business. The videos will be shown, starting on February 10th, and will continue every week (except for the spring break) until the end of April.

  • Wednesdays, 5:00 PM – 7:00 PM, BB 121
  • Seminar Series Information

    Professor Jay Forrester, in the fall of 1999, conducted a seminar series for PhD students in System Dynamics. Each of the eleven three-hour sessions is devoted to a different stand-alone topic, which should be of benefit to any student or practitioner in the field. The series is not a progressive tutorial for learning System Dynamics, but covers related concepts and philosophy.

    In an educational setting, these sessions can be used as assignments to be viewed in preparation for a follow-up class discussion. Those who are applying System Dynamics in business and social situations should find these sessions useful in broadening their understanding of the field.

    Sessions A through E have already been shown. This week’s showing resumes with Session F: Group Model Building. What is group model building and why do we do it? Guest speaker, Professor George Richardson, opens the session with a list of group roles that various people can play in the group model building process. Richardson stresses that the model is a tool to enable deep conversation among the participants. He discusses different stages in building a System Dynamics model as a group. The ultimate goal according to Richardson is to develop great conversations as a step toward insightful models.

    We are confident every attendee will enjoy the sessions. Hope to see your there.

    iSDG Model – Tool for designing SDG strategies and roadmaps

    Millennium Institute is pleased to announce the launch of the Integrated Sustainable Development Goals Planning Model (iSDG). The iSDG model simulates the fundamental trends for SDGs until 2030 under a business-as-usual scenario and supports the analysis of alternative scenarios. It covers all the 17 Goals, and facilitates a better understanding of the interconnections of the goals and targets, in order to develop synergetic strategies to achieve them. The model’s structure can also be expanded to support the analysis of other country-specific development issues beyond the SDGs.

    The iSDG model is useful both in the early stages of policy design, to support scenario exploration; and in the advanced stage, when sector-specific interventions can be jointly simulated to assess their combined effect. This enhances the ability of policy makers and planners to evaluate and prioritize projects, investments, and strategies based on anticipated impacts, and to visualize how the combination of interventions lead to positive synergies.

    For more information and to download the beta version of the model, visit

    Call for Papers: 34th International Conference of the System Dynamics Society

    The Web Portal is now open to accept paper submissions as well as proposals for workshops and tutorials to be presented in Delft, the Netherlands from July 17-21, 2016. Please consider the theme for this year: “Black Swans and Black Lies: System Dynamics in the Context of Randomness and Political Power-play.”
    System Dynamics has proven useful to analyze dynamically complex economic, social, and environmental issues. It is an effective methodology for designing robust systems and policies. We hope to challenge this usefulness in two areas: first, when systems are prone to be affected by random events that we were not able to include in our models; second, when System Dynamics models are not used in a fair or transparent way.

    For a detailed list and descriptions of conference session topics, visit “Threads for 2016” website. The submission deadline is March 23rd. For more information, please visit “Call for Papers” website.

    Fires burning in Tasmania – system collapse?

    “This is bigger than us. This is what climate change looks like, this is what scientists have been telling people, this is system collapse,” fire ecologist David Bowman, was quoted in the article Tasmania fires: First images of World Heritage Area devastation emerge, show signs of ‘system collapse’ on The first images to emerge from within Tasmania’s fire-affected World Heritage Area (WHA) have illustrated the level of destruction caused by bushfire, as experts warn such incidents are signs of a changing climate. 11,000 hectares of WHA are incinerated by the Tasmania bushfires. Wildlife, including wallabies and wombats, are also affected and experts say parts of the Central Plateau will not recover.

    Public Radio International interviewed member John Sterman

    Public Radio International invited member John Sterman to consider whether big oil companies are really on board for addressing climate change.

    New Publication by United States Environmental Agency

    The paper “A System Dynamics Model for Integrated Decision Making: The Durham-Orange Light Rail Project” has recently been published online at the EPA Science Inventory. The purpose/objective states “The United States Environmental Protection Agency (US EPA) Sustainable and Healthy Communities Research Program (SHC) has committed to developing systems approaches that enable communities to act on an enhanced understanding of these interconnections and to comprehensively account for the full costs and benefits of community decisions in the social, economic, and environmental dimensions. This report documents the development and testing of a System Dynamics (SD) model as a decision support tool for community sustainability with the proposed Durham-Orange Light Rail Project (D-O LRP) in Durham and Orange Counties, North Carolina, as a case-study.” The description of the work includes “In the first phase of this modeling effort, a conceptual model for the D-O LRP was designed with a high degree of input from stakeholders, including representatives from the regional transit authority, county health department, stormwater management department, and city and regional land use and transportation planning departments, among others. This conceptual model served as a framework for the operational SD model, which was built to evaluate a number of policy scenarios, many of which were also suggested by stakeholders. The operational model was subjected to rigorous quality assurance tests, including the sensitivity of the model to assumptions and inputs, and the evaluation of outcomes – social, economic, and environmental – resulting from actions that emanate from or impinge on the D-O LRP.”

    New Article in Early View at the System Dynamics Review

    Read Erik Pruyt and Tushith Islam’s article “On generating and exploring the behavior space of complex models” in Early View for the System Dynamics Review.

    New Article in Jacobs Journal of Medicinal Chemistry

    The article “Systems Thinking for Medicinal Chemists” by Robert E. Smith, Kevin Tran, and Kristy M. Richards has been published in the Jacobs Journal of Medicinal Chemistry. The article shows an interesting view of the landscape of medicinal chemistry; and its increased use of technology and big data, and government initiatives. The abstract states: “Systems thinking has become an essential part of modern medicinal chemistry and new drug development. It is based on the concepts that complex problems almost always have multiple causes and that there are often connections that have not always been obvious. In contrast to reductionist thinking, systems thinking uses network theory and nonlinear mathematics to prevent, diagnose, treat and even cure diseases. Systems thinking is an integral part of predictive, preventive, personalized and participatory (P4) medicine.”

    2016: New System Dynamics Song

    “System Dynamics Song: Close The Loop” was originally written and performed in 1976 at Geilo, Norway Conference by a group of attendees who protected their anonymity under the name of the Transient International Consortium at Geilo (TICAG). The song had an encore performance at the 2000 Bergen Conference.

    This year, there is a new song: “Looking for Feedback Loops.” Below are the artists’ stories and photos.

    Wolfram Reinhard, born on the 6th of June 1990 as Wolfram Pallaske, is a student at the Leibniz University Hannover and is focusing on regional development in his Bachelor’s thesis. In 2009, he graduated high school with music as one of the main courses, but he started learning to play several instruments when he was six. After his brother Georg wouldn’t stop bugging him, he recorded and cut the song “Looking for feedback loops”, of which Georg wrote the text himself. Wolfram Reinhard has already finished several music related projects, which he was realizing outside of the curricula of his temporary education, alongside which he produced one CD. The strong positive feedback on the song “Looking for feedback loops” surprised the artist.

    Georg Pallaske, born on the 4th of October 1987, is a current student in the European Masters Programme in System Dynamics (EMSD). After his Bachelor’s degree in Business Administrations, he entered the EMSD because of the potential the he saw in the application of the method with expert-groups (group-model building). After one and a half years of studying SD, and a lot of conversations with peers and experts, he decided to write a song about SD which compiles the things that are still at odds within the field, and put them into a nice message that comes across easily. And thanks to his little brother the song is available in a version that people might even enjoy listening to. Georg Pallaske is currently in the last semester, and will soon start writing his masters’ thesis.

    Thanks to Wolfram and Georg!

    2016 Behavioral Operational Research Summer Program

    The Systems Analysis Laboratory at Aalto University, in collaboration with the Behavioral Operational Research community, is initiating an international BOR Summer School at the Otaniemi Campus of Aalto near Helsinki, Finland from May 15-22.

    Using this emerging specialization in operational research, participants will investigate behavioral issues related to model based decision making and develop models to describe human behavior in problem solving and complex settings. Pioneers of the field will present on topics such as problem structuring, multi-criteria decision making, heuristics and biases, simulation, systems thinking and forecasting. Brain researchers will demonstrate new measurement techniques, including brain imaging, and illuminate their value in understanding human emotions and behavior. Additionally, students will have opportunities to discuss their research with peers and distinguished presenters attending the summer school.

    Doctoral and advanced master’s students, as well as post docs, from the behavior, social, computational and organizational sciences are invited to attend this inaugural training. Interdisciplinarity is key in BOR, therefore knowledge of OR is not a prerequisite to participation.

    The application deadline for participation is February 20, 2016.

    New System Dynamics Article in Risk Analysis

    The recently published the article “A Simplified Approach to Risk Assessment Based on System Dynamics: An Industrial Case Study” in the journal Risk Analysis is currently available electronically (ahead of print). The authors are Emmanuel Garbolino, Jean-Pierre Chery and Franck Guarnieri. The abstract states “Seveso plants are complex sociotechnical systems, which makes it appropriate to support any risk assessment with a model of the system. However, more often than not, this step is only partially addressed, simplified, or avoided in safety reports. At the same time, investigations have shown that the complexity of industrial systems is frequently a factor in accidents, due to interactions between their technical, human, and organizational dimensions. In order to handle both this complexity and changes in the system over time, this article proposes an original and simplified qualitative risk evaluation method based on the System Dynamics theory developed by Forrester in the early 1960s. The methodology supports the development of a dynamic risk assessment framework dedicated to industrial activities. It consists of 10 complementary steps grouped into two main activities: System Dynamics modeling of the sociotechnical system and risk analysis. This System Dynamics risk analysis is applied to a case study of a chemical plant and provides a way to assess the technological and organizational components of safety.”

    New BLOG: Overcoming the Systemic Challenges of Inequity

    Bridgeway Partners has started a new blog post that describes several dynamics and assumptions that lead inequity to persist, and six high leverage interventions leaders can pursue to create greater equity in their communities. The announcement about the new blog post states “related problems of structural racism and economic inequality undermine the moral as well as social and economic fabrics of our country.” Many of the ideas in this post are drawn from David Peter Stroh’s book Systems Thinking for Social Change.

    System Dynamics Review Early View

    A new System Dynamics Review early view article has been released. Read Albert Munoz and Matthew Pepper’s publication “Maintaining stock and flow: a constructive alignment approach to training system dynamicists.”

    Member Simon Shepherd, and Chandra Balijepalli recently published the article “A game of two cities: A toll setting game with experimental results” in the journal Transport Policy. The paper extends the idea of competition between cities by setting up a System Dynamic model of two cities which includes modes such as car, bus, train and walking and cycling. This paper innovates by integrating the simulation of land use transport interactions with a class room style experimental game and analyses the gaming strategies from a continuous repeated prisoner’s dilemma involving setting of tolls to maximize the welfare of residents. Highlights of the paper include the development of a twin city land use transport interaction model; the incorporation of gaming facility to explore competition, and analysis of toll setting gaming experiment and use of information over regulation in policy making.

    Other recent related papers on this topic include “Cordon tolls and competition between cities with symmetric and asymmetric interactions” published in the Journal of Transportation by Chandra Balijepalli and Simon Shepherd and “A review of system dynamics models applied in transportation” by Simon Shepherd published in Transportmetrica B: Transport Dynamics.

    3rd Annual South Africa System Dynamics Conference: A Report

    The 3rd Annual South Africa System Dynamics Conference was held at the Eskom Research, Testing and Development Centre in Johannesburg on November 16, 2015. This conference, collaboratively hosted by Eskom and the South Africa Chapter, explored a variety of topics, including: energy, gangsterism, health systems, Ponzi schemes, project prioritization, chemical usage, situational awareness, innovation process and green economy. 75 participants who were academics, researchers, government officials, consultants and students, attended the workshop.

    Several awards and recognitions were given at the conference for outstanding achievement:

    • Andries Botha, winner of Best Presentation for his work titled “Ponzi Schemes—A System Dynamics Perspective (It’s not all about work!).”
    • Danie Booyens, winner of Best Contribution for his paper “System Dynamics Simulation using Non-Traditional Platforms.”
    • Jacobus Smit van Niekerk, Willem Jonker, Aliza Pienaar, Theodore York, Juan Oosthuizen, and Lize Duminy, all students from Stellenbosch University, winners of Best Student Paper. These six students co-authored the paper “A System Dynamics Approach to Understanding the Implications of a Green Economy Transition in the Western Cape Province of South Africa” with Prof Alan Brent, Dr Josephine Musango, and Imke de Kock.

    System Dynamics Application Used in Investment Research Methods

    The FA Online edition of Financial Advisor, on January 12, posted the article “Cucchiaro Launches RIA, Hedge Fund.” Stephen J. Cucchiaro has formed 3EDGE Asset Management, a Boston-based Registered Investment Advisor (RIA) where he will serve as president, CIO and chairman of the investment committee. Parts of the article follow: Cucchiaro, who uses a scientific methodology in his investment strategy, began managing investment portfolios in 1994 and was founder, president and CIO of Windward Investment Management. … Cucchiaro uses proprietary investment research methods, including applications of engineering, System Dynamics and complexity economics concepts to analyze the relationships that drive markets. “Our approach seeks to identify asset classes and geographies that may be undervalued as a result of the macro-inefficiencies inherent in the global markets,” Cucchiaro said. “We are looking to capture the potential for material long-term price appreciation of these undervalued asset classes and geographies over different time frames.”

    The firm will apply a multiplayer game theory framework to better understand how policies by actors like central banks might influence the direction of capital markets. “We may be at a critical juncture in the global markets,” Cucchiaro said. “The massive central bank intervention since 2008 has, in many instances, elevated asset prices. In the years ahead, attractive investment returns, particularly on a risk-adjusted basis, could be difficult to achieve as markets may be susceptible to diminishing returns from monetary stimulus. In such an environment, more passive buy and hold strategies could prove to be disappointing, while short-term trading strategies could also be counter-productive since investors may be whipsawed by market volatility.” …

    Mr. Cucchiaro gave a plenary presentation at the 2013 Cambridge Conference titled “A System Dynamics Approach to Modeling the Global Capital Markets.”

    New Book by Society Member Hassan Qudrat-Ullah

    Hassan’s book is useful to managers, practitioners, teachers, researchers and students interested in the design and assessment of policy for complex and dynamic energy systems.

    Demonstrating the Utility of SD Modeling for Synthesizing Epidemiologic Evidence to Inform Public Policy

    Member David Lounsbury, along with Anton Palma, Nicholas Schlecht and Ilir Agalliu recently published the article “A System Dynamics Model of Serum Prostate-Specific Antigen Screening for Prostate Cancer” in the prestigious American Journal of Epidemiology. The article is currently available electronically (ahead of print). Their publication adds to the on-going deliberation about the benefits and harms of regular prostate-specific antigen (PSA) screening for adult men. Since 2012, US guidelines have recommended against PSA screening for prostate cancer, which was based mainly on the results of two large clinical trials [i.e., the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening trial and the European Randomized Study of Screening for Prostate Cancer (ERSPC)]. However, evidence of screening benefit from the PLCO and the ERSPC trials has been inconsistent, due partly to differences in participant noncompliance and contamination. In their article the authors describe how they used System Dynamics modeling to replicate the PLCO trial and to extrapolate follow-up to 20 years, correcting for effect attenuation in a three different scenarios. Two of three simulated scenarios showed a benefit of PSA screening, with relative risks of 0.62 (95% confidence interval: 0.53, 0.72) and 0.70 (95% confidence interval: 0.59, 0.83) for cancer-specific mortality after 20 years, demonstrating that after correcting for noncompliance and contamination, there is potential benefit of PSA screening in reducing prostate cancer mortality. This work underscores the utility of System Dynamics modeling for synthesizing epidemiologic evidence to inform public health policy.

    Six PhD Scholarships in the Centre for Systems Studies, Hull University Business School

    The Centre for Systems Studies, based in the Business School at the University of Hull (UK), has a strong international reputation for its cutting edge work on the theory, methodology and practice of systems thinking. Six scholarships for the Systems Science PhD program are available to offer to successful candidates wanting to start a PhD in September 2016. The deadline for applications is 29 February 2016. These scholarships are structured into three research areas, each of which has a pair of scholarships associated with it:

    Resilient Communities for Sustainable Development: exploring the potential for harnessing ecosystem services and local sustainable development to promote the physical, social, mental and economic well-being of communities in different socio-economic settings. One PhD student will work on local “green economy” models and their impact on the socio-economic well-being of the community, and the other will work on the exploitation of ecosystem services for health and well-being.

    Resilience in Cyberspace: examining the opportunities and challenges for public and private sector service providers operating in the digital economy. The focus will be on internet-based business models and their sustainability. One PhD student will focus on the way social media and pervasive technologies furnish data and networks that can be harnessed by businesses; and the other student will focus on how the digitisation and connectivity afforded by these technologies can expose service providers and consumers to ethical and security challenges.

    Marginalisation and Conflict: extending the capabilities of systemic action research methodologies and complexity science to address the dynamics of conflict and marginalisation and their consequences in complex social systems. The first PhD student will focus on health/welfare settings, and the second will focus on social inclusion/exclusion, collective identities and radicalisation. Both students will work with the wider team of academics to develop a framework for understanding and explaining the systemic phenomena associated with the dynamics of marginalisation, in order to inform the design of policies and interventions to minimise the social costs of this.
