2021 International System Dynamics Conference

The International System Dynamics Conference is an annual event where people from all over the world interested in the practice of System Dynamics and systems thinking gather. Now in its 39th year, the Conference appeals to audiences across industry and academia. These conferences introduce newcomers to the field, keep practitioners aware of current developments, and provide unparalleled networking opportunities. Participants come from business, universities, K-12 education, not-for-profits, government, consulting, the healthcare sector, and beyond.

Due to the COVID-19 pandemic the 2021 ISDC has changed its format to be fully virtual. It will be accessible and inclusive for all participants around the world.

2021 Student-Organized Colloquium

The Student-Organized Colloquium is a free, one-day event organized by the Student Chapter of the System Dynamics Society held on the first day of the International System Dynamics Conference (ISDC). The Student-Organized Colloquium promotes dialogue among system dynamicists of varying fields, levels of training and backgrounds and creates spaces to have meaningful conversations about the topics that we all care about so that everyone can share and receive feedback to improve their work.

The format of the event consists mainly of breakout sessions in which doctoral, masters and undergraduate students, as well as practitioners, professionals and academics in any field who are new to System Dynamics (less experienced, mentees, juniors) can discuss their ideas and concerns, and get mentored by more experienced system dynamicists (mentors, seniors).

2021 Summer School Introductory Course

Held prior to the conference, the System Dynamics Summer School provides a unique opportunity to learn (or review) the basics of System Dynamics and get exposed to real-world applications of the method. We will record all preparation sessions for viewing. The first week will be on your own to get exposure to software and systems thinking and to start watching the topic lectures. We will use the second week of Summer School week for live discussion of topics and assignments. We will have a dedicated website for materials, homework, and Q&A. This year’s Summer School will focus on introductory and intermediate topics.

For more information, please visit the Summer School page.

Economics SIG: Garry Piepenbrock presents “Toward a Theory of the Evolution of the Global Political Economy: Competition between Liberal and Coordinated Market Economies”

In this Collective Learning Meeting (CLM), WPI System Dynamics and the System Dynamics Economics SIG host Garry Piepenbrock ( who will present:

Toward a Theory of the Evolution of the Global Political Economy:

Competition between Liberal and Coordinated Market Economies

Short Description: This presentation explores how wealth is created and distributed within and between nations. System Dynamics is used to numerically simulate the nonlinear dynamic behaviour of constrained competition between Liberal Market Economies (LMEs) and Coordinated Market Economies (CMEs) as a multi-predator-prey system which generates overshoot, limit cycles and chaos.

Critiques and feedback on the internal structural validity (i.e. the logic of the causal relations) of the model would be appreciated.

Biography: Garry is a 17-year-old high school student on scholarship to Eton College in the UK, where he has won 13 awards in essay competitions in Economics, Politics, Philosophy and History, including a John Maynard Keynes Prize (where Keynes was a student). He founded the John Maynard Smith Society for Innovation in Interdisciplinary Inquiry and is a Secretary of the Entrepreneurship Society. He is on the Committees of the Economics and Politics Societies and he is an editor of the Economics and Politics journal, Etonomics ( He is a member of the System Dynamics Society, a member of the Young Scholars Initiative of the Institute for New Economic Thinking, and a Fellow of the International Institute for Strategic Leadership ( where he is passionate about bringing STEM to the social sciences through his modelling and research on ‘The Evolution of Economic Ecosystems’ and its dissemination via short educational films (

Economics SIG: Khalid Saeed presents “Connecting Feedback Map with Computable Model”

Join us Friday, March 12th 3:00 PM – 4:00 PM ET (Boston time. Here is a time converter). In this Collective Learning Meeting (CLM), WPI System Dynamics and the System Dynamics Economics SIG host Prof. Khalid Saeed ( who will present:

Connecting Feedback Map with Computable Model

Short Description: This presentation addresses the disconnect between feedback structure of a system and its computable stock/flow model, which has lead to a separation between system thinking and system dynamics, also creating rather arbitrary explanations for the behavior of the system modeled. The presentation discusses how the two representations are related and how they should be connected in a formal computer model.

Biography: Khalid Saeed is Professor of Economics and System Dynamics at Worcester Polytechnic Institute. He works on applying system analysis to a variety of domains subsuming economics, public policy, healthcare and management.

We will record this presentation and post it to the SD Econ SIG YouTube Channel. We will also livestream the presentation to the Econ SIG YouTube.

Mahshid Zolfaghari presents “Impact Evaluation of European School Fruit and Vegetable Scheme”

Join us online Friday, March 5th 3:00 PM – 4:00 PM ET (Boston time. Here is a time converter).

In this Collective Learning Meeting (CLM), WPI System Dynamics hosts Mahshid Zolfaghari ( who will present:

“Impact Evaluation of European School Fruit and Vegetable Scheme”

Short Description: I have developed a causal loop map on “European school fruit and vegetable scheme”, to investigate the low children’s fruit and vegetable consumption, and how this policy has influenced it.

Questions for the Audience: I would like to ask audience, if they can guide me through quantification of my causal loop map, share some of the challenges that I had in quantification way. I also like to ask if the problem that I am studying suits the system dynamics method at all.
