University of Albany Students Participate in World Climate Exercise

How do we find pathways to limit temperature change and its effects? 45 students, faculty, and community members from the University at Albany, State University of NY enacted the World Climate Exercise climate negotiation role play, learning about the near-term actions to protect our future world. The System Dynamics Group at UAlbany organized the event, with Eliot Rich as facilitator and Babak Bahaddin as the Secretary-General of the UN. Dr. Rich noted: “This World Climate Exercise was different than others I’ve run. The need for determination and activist-driven optimism has never been greater. The WCE provides both.”
Participants surveyed after the session loved the role play and interactions built into the exercise. Through the debrief, attitudes changed from hopelessness to engagement:

  • “I was surprised how much developing countries contributed to global warming.”
  • “A moving simulation; Activism and consensus is more important.”
  • “I want to work with businesses to help them mitigate climate change; the best part was the learning process at the end.”
  • “I will work harder towards my political classes and share this knowledge with friends, family and where I work.”
  • “I plan to think more about my daily actions and what I can change.”

Starting next year, the World Climate Exercise will be integrated into the University’s MBA programs through its G3 – Going Green Globally capstone course. The exercise will be used to introduce the entire first year class to the systems perspective on sustainability, bathtub dynamics, feedback, and stakeholder dynamics. As part of their course project, students bring these concepts to bear on sustainability strategies and tactics for local businesses and non-profit agencies.

Climate Conference Yields New Analysis

At the recent UN climate conference in Morocco, an MIT team including Society member John Sterman worked together with the Climate Interactive to discuss issues concerning the Paris agreement. Through the use of models and educational tools, they are helping political leaders, policymakers and the public to see the urgency of emissions cuts, how plans that move past the Paris agreement make an impact and potential problems. The Climate Interactive has released new analysis on the 2050 climate goals of the United States, Canada and Mexico. The full report is posted on the Climate Interactive website.

Member John Sterman Quoted in Live Science Article on Climate Change

In the article “How to Avoid Stephen Hawking’s Dark Prediction for Humanity” published by Live Science, John Sterman responded to a statement made by Stephen Hawking regarding the extinction of humans and the need to colonize other planets. John states “While I respect Stephen Hawking enormously, speculating on how long Homo sapiens will survive before extinction is foolish. Whether we survive and thrive or descend into chaos is not something to predict or lay odds on, but a choice to be made.” John concludes by saying “Anyone who thinks we can solve these problems by colonizing other worlds has been watching too much ‘Star Trek.’ We must learn to live sustainably here, on the one planet we have, and there is no time to lose.” Read more in the full article.

System Dynamics Review Early View

A newly released Early View of the System Dynamics Review features the research article “Estimating the parameters of system dynamics models using indirect inference,” by Society member Hazhir Rahmandad and his colleagues, Mohammad Jalali, Niyousha Hosseinichimeh and Andrea Wittenborn. The article is now available on the Wiley Online Library and will later be published in an issue of the System Dynamics Review.

In Memoriam

It is with great sadness that the System Dynamics Society announces that Jay W. Forrester, Professor of Management Emeritus at MIT, has died at the age of 98 on November 16, 2016.

Jay founded what became the field of System Dynamics in 1956 and has had a profound and lasting influence on it throughout its 60-year history. A lifelong innovator, Jay was a pioneer in digital computing and helped create the computer age in which we all live today. Trained in electrical engineering, Jay came to MIT in 1939, where he worked on feedback control servomechanisms during World War II. After the war, Jay directed the MIT Digital Computer Laboratory, where he led the design and construction of Whirlwind I, one of the world’s first high-speed digital computers. He invented and holds the patent for magnetic core memory, the dominant form of random access memory (RAM) for decades (even travelling to the moon with the Apollo astronauts), until it was eventually replaced by semiconductors. Whirlwind became the basis for many innovations, from numerically controlled machine tools to SAGE, the first integrated continental air defense system.

Invited to join the faculty of the MIT Sloan School of Management in 1956, Jay created the field of System Dynamics to apply engineering concepts of feedback systems and digital simulation to understand what he famously called “the counterintuitive behavior of social systems.” His groundbreaking 1961 book, Industrial Dynamics, remains a clear and relevant statement of philosophy and methodology in the field. His later books and his numerous articles broke new ground in our understanding of complex human systems and policy problems. Jay officially retired in 1989, but continued his work unabated, focusing on promoting the use of System Dynamics in K-12 education.

John Morecroft (London Business School) wrote “My life was changed by Jay Forrester. His influence came in two distinct ways, from personal encounters and from the research environment he created as founder and leader of the System Dynamics Group at MIT-Sloan. I spent a decade at MIT, first as a doctoral student and later as a member of faculty at Sloan. So there is much to remember.”

George Richardson, Professor Emeritus at the University at Albany, said “Jay opened a path that gave many of us voices we did not know we had. What a life of towering achievements, to have been crucial to the development of computing in its infancy, and then to show us how to use its power to help us make progress together on seemingly impossible problems. I am profoundly grateful for his presence and influence in my life. ”

Professor John Sterman, the Jay W. Forrester Professor of Management at MIT and Director of the MIT System Dynamics Group said “Like so many others, I was fortunate to be able to work with and learn from Jay. He constantly challenged us to think deeply, speak plainly, and work on issues that matter, not only to build understanding, but to act. And he always led by example.”

Roberta Spencer, Executive Director of the System Dynamics Society, remembers, “During a conversation Jay said to me ‘figure out a way to have courage.’ Jay said this to everyone—I took it to heart and it changed my life.”

Jay was married for sixty-four years to Susan (Swett) Forrester, who died in 2010. Survivors include one daughter, Judith Forrester of Concord, Massachusetts; two sons, Nathan B. Forrester of Boca Grande, Florida, and Ned C. Forrester of Falmouth, Massachusetts; four grandchildren, Matthew S. Forrester of Arcadia, CA, Julia D. Forrester of Bois, ID, Neil T. Forrester of Torrance, CA, and Katherine J. Forrester of Chicago, IL as well as two great grandchildren Everett Chen Forrester and Faraday Chen Forrester, both of Arcadia, CA.

Please visit the webpage dedicated to Jay and write about how Jay touched your life. A full obituary and funeral arrangement details will be available soon.

Special Editorial by Yaman Barlas Featured in the System Dynamics Review

Yaman Barlas, Executive Editor of the System Dynamics Review, delivered an important message in his editorial in the last issue of the SDR. Yaman discusses the challenges involved in increasing the number of papers submitted to the journal. He states “My concern is that there is currently a narrow, almost parochial perception of SDR, due to the confusion of philosophy and principles of System Dynamics with tools and software. My suggestion is simple: System Dynamics belongs to the larger field of “sciences of dynamic systems” and SDR is a natural platform to publish good systemic-dynamic research and applications, regardless of what tools or software they use.” Yaman argues System Dynamics Review will reach its full potential by SD Society members, as well as other dynamical system scientists submitting their best work to SDR. The full editorial is freely accessible through the Wiley Online Library.

An Article on Finding the Optimal Model Complexity

Professor Daniel Peter Loucks explores the topic of simplifying models to meet changing information needs in his November 3rd blog post, “Model complexity – What is the right amount?” In the article, Loucks writes “Modelers of real systems addressing real problems have the job of providing the information needed by those making recommendations or decisions. But those individuals themselves often don’t know what they will need or want until they get what our models give them.” He discusses the relationship between the modeler and the stakeholder, stating “One way to build that level of trust and at the same time help guide modelers in determining just what level of complexity may be most appropriate is to start simple and only add complexity when it is called for.” Loucks supports this point by reviewing two case studies. Read the full article on the Integration and Implementation Insights blog.

SD Research Article Explores Work-Family Conflict in the Construction Industry

The research article “System Dynamics Model and Simulation of Employee Work-Family Conflict in the Construction Industry,” by Guangdong Wu, Kaifeng Duan, Jian Zou, Jianlin Yang, and Shiping Wen, has been published in the International Journal of Environmental Research and Public Health. In the article, the authors explore how work-family conflict effects not only the family life of an employee, but also how the conflict impacts the employee’s job performance. The authors built a model that focuses on the construction industry in particular. In the abstract, they explain “In order to analyze the dynamic evolution of construction industry employee’s work-family conflict between work and family domains, this paper constructs a bi-directional dynamic model framework of work-family conflict by referring to the relevant literature. Consequently, a System Dynamics model of employee’s work-family conflict in the construction industry is established, and a simulation is conducted.” The full paper is available on the MDPI website.

Protecting the Climate: SD Model Used to Analyze Policy Changes

In the Citizen-Times article “Climate-change models inform negotiators, engage regular folks,” author Mike Cronin discusses the important role the Climate Interactive has in environmental policy. The Climate Interactive is a non-profit organization founded in 2010, with headquarters in Washington D.C. and additional offices in Asheville, North Carolina, Cambridge, Massachusetts, and Hartland, Vermont. The Climate Interactive, along with Tom Fiddaman of Ventana Systems, created the System Dynamics model used to determine the effects of proposed environmental policies. The Climate Interactive plays a significant role in climate policy, in fact, during the recent Paris Climate Agreement negotiations, attendees regularly conferred with the researchers and scientists at the Climate Interactive. The models have remained as a free and open source, and are used by many. As quoted in the article, Climate Interactive co-director Elizabeth Sarwin states “We make our simulations easy to use and freely accessible to people all over the world who want to understand what it will take to protect the climate. We use our tools to open up the discourse about infrastructure investments that impact the climate to bring more people and more perspectives into decision-making.” Read more in the full article on the Citizen-Times website.

Psychology SIG to Increase Focus by Including Human Behavior

The Psychology SIG proposes to change their name to the Psychology and Human Behavior SIG. As noted by the co-chairs of the SIG, David Lounsbury and Pascal Gambardella, “Our request to change the SIG’s name comes from members’ observations that psychology, as a primary domain focus, describes only a fraction of what we actually discuss, critique, and support. This is evidenced in the workshops and presentations that the SIG has organized and supported.” So far the request has been met with positive responses, and ten members have added their name to the formal request. Members of the Society may comment on the name change, contact David and Pascal by email. The Psychology SIG welcomes new members, please see the website for more information.

New Publication: System Dynamics Models Used to Analyze PTSD

A new research article titled “A Dynamic Model of Post-Traumatic Stress Disorder for Military Personnel and Veterans,” by members Navid Ghaffarzadegan, Mohammad S. Jalai and their Virginia Tech colleague Alireza Ebrahimvandi, has recently been published in PLOS ONE. In this study, the authors developed a System Dynamics simulation model of the population of military personnel and veterans affected by this mental illness and then used the model for an analysis of health policy. The full paper is available on the PLOS ONE website. Mohammad Jalai discusses the topic further in a related article published in the Conversation, “Fighting another war: How many military personnel and veterans will have PTSD in 2025?” When speaking of the results, Mohammad concludes, “…that in a post-war period there is no easy solution for overcoming the problem of PTSD, and the current screening and treatment policies used by the VA and the DOD must be revolutionized to have any noticeable effect. The VA and the DOD should work together and try to offer timely service to patients. However, we showed that they cannot do much to decrease health care costs. These are the consequences of wars.” For the use of the public and policymakers, the authors have provided access to the online model.

Now Available in Print: Principles of Systems

In Principles of Systems, author Jay W. Forrester explains the basic principles behind system behavior. The book introduces the concepts of structure and dynamic behavior on which were based the author’s earlier books, Industrial Dynamics, 1961 and Urban Dynamics, 1969. Due to the general nature and wide applicability of the principles discussed, the book has been accepted as a starting point for teaching dynamic systems on many multidisciplinary courses on urban, ecological, corporate and other complex social systems. The reprinted edition of Principles of Systems can be ordered through the Society’s book store on our website.

Your Assistance is Requested in Creating a Database of K-12 Teachers

Member Diana Fisher is reaching out to colleagues in the field of System Dynamics for assistance in creating a database of K-12 teachers (globally) who are using systems thinking (BOTGs, causal loops, ladder of inference, iceberg, and/or Behavior of a Systems Thinker cards) and/or are using System Dynamics models or are having students build System Dynamics models in their classes. Once these teachers are identified, they would be invited to participate in the annual international research conference when the conference is relatively close to their location. Diana would also like to determine how best to help network those teachers to share resources. If you know any K-12 (pre-college) teachers who are using ST/SD in your area, Diana requests that you send her their names and contact information (email to fisherd at so she can communicate with them to see if they are willing to be part of the database. Please note that she would like to have the information within the next 2-3 weeks. On behalf of Diana, thank you for any help you can provide!

Partnership Between Universities Benefits Students of Public Health and System Dynamics

The University of North Dakota School of Medicine and Health Sciences (UND SMHS) will partner with colleagues at the University of Bergen in Norway (UiB) to train students in each of the university’s areas of expertise. As System Dynamics is increasing applied to analyzing public health topics, the need for “cross training” students of public health and students of System Dynamics is evident. The Norwegian Centre for International Cooperation in Education under the Partnership Program with North America will fund the project from January 2017 through December 2020. The grant titled “Model-based Public Health Education,” was awarded to UND SMHS Assistant Professor Arielle Selya, PhD, and Master of Public Health Founding Director and Professor Raymond Goldsteen DrPH, in collaboration with Associate Professor David Wheat and Professor Pål Davidsen in the Department of Geography at UiB. The grant will allow the exchange of studies for up to five students per year, providing students the opportunity to gain highly marketable skills. Read more about this project in the full article.

Member Jeroen Struben Appointed Assistant Professor at EM Lyon Business School, France

Jeroen Struben has recently been appointed assistant Professor at EM Lyon Business School in Lyon, France. Jeroen will be teaching within the Strategy and Organization Department. Among other classes, he will teach the new master level course “Systems Thinking and Sustainability.” Jeroen studies dynamics of market formation and transformation, addressing questions, such as “How do alternative products and practices penetrate in the marketplace – or society at large, rather than falter?” Jeroen analyzes market formation processes, focusing on the over-time interactions across stakeholders working through both social and material adoption challenges. He conceptualizes and studies these efforts as market formation processes because significant uptake of such products involves the joint development of consumer familiarization, complementary infrastructure, and technology improvement. Jeroen tackles these problems using simulation and empirical analysis of large spatiotemporal datasets. His current research program consists of three projects: (I) Market formation for alternative fuel vehicles, (II) Market formation for nutritious food, and (III) Market formation theory. Jeroen’s research produces insights for both scholars and practitioners about coordination and collective action across organizations, industries and governments. Congratulations to Jeroen! On behalf of the Society, we wish you the best of luck in your new position.

Breaking the Deadlock: How “Qualitative System Dynamics” Can Help to Overcome Emergency Department Crowding in Singapore

The article “Emergency department crowding in Singapore: Insights from a systems thinking approach,” by members Lukas Schoenenberger, John Ansah, and David Matchar, along with their colleagues from Duke-NUS Graduate Medical School Singapore, Steffen Bayer, Rajagopal Mohanavalli, Sean Lam, and Marcus Ong, has been published in the open access journal SAGE Open Medicine. The work vividly shows how causal loop diagramming can be used for both eliciting the systemic structure of emergency department crowding and causally inferring (relative) impacts of different policies currently debated by policy-makers in Singapore. The full article can be viewed on the SAGE Open Medicine website.

System Dynamics Provides Businesses with a Path to Improvement

The article “Absorptive capacity, technological innovation, and product life cycle: a System Dynamics model,” by Bo Zou, Feng Guo and Jinyu Guo, was recently published in the web based journal Springer Plus. The article is a summary of the authors’ study of using System Dynamics modeling to provide analysis for adjusting the management policies of businesses. In the abstract, the authors state “While past research has recognized the importance of the dynamic nature of absorptive capacity, there is limited knowledge on how to generate a fair and comprehensive analytical framework. Based on interviews with 24 Chinese firms, this study develops a system-dynamics model that incorporates an important feedback loop among absorptive capacity, technological innovation, and product life cycle (PLC).” The full article can be viewed on the Springer Plus website.

Working to Meet Sustainable Development Goals

In his blog post “Business can rock the world,” Bjørn Kj. Haugland, Executive Vice President and Chief Sustainability Officer in the DNV GL Group, discusses the forecast of Sustainable Development Goals (SDGs). The article features details about the DNV GL report “The Future of Spaceship Earth,” a study of seventeen SDGs each paired with a leading global company with relevance to a particular goal. Haugland notes “In our quest to assess the likelihood of the SDGs being achieved by 2030 we took, as a starting point, the long-term forecast created by one of the original members of the Club of Rome, Jørgen Randers. We then surveyed over a dozen forecasting models. Of these, we found the two most suitable supplementary models were the System Dynamics-based “T21” model of Millennium Institute [System Dynamics], and the Regional Integrated model of Climate and the Economy (‘RICE’) led by Professor William Nordhaus of Yale University. Our team performed structural sensitivity analyses using these two supplemental models, and drew on the T21 model in particular to assess SDG issues and targets not covered by the Randers model.”

The results were expressed in terms of a scorecard, which revealed progress in the areas of health, innovation and education, but shows the sustainable development goal in climate action falling short across the board in all five global regions.
