6th Annual System Dynamics Competition by the South Africa System Dynamics Chapter
System Dynamics Competition
CORRECT TIME: 2 PM CENTRAL EUROPE
The System Dynamics Society’s South Africa Chapter is hosting a System Dynamics Competition that offers participants the opportunity to learn new modeling skills directly from experts, collaborate with others, and win prizes! The competition is suitable for beginners, whether or not they have experience.
System dynamics is increasingly essential as humanity faces increasingly complex challenges. System dynamics integrates various fields through systems thinking and mathematical computer-based simulations, improving decision-making and forging systemic solutions rather than symptomatic fixes.
This year’s competition is unique in that participants will receive a small, working simulation and will expand its structure to derive non-intuitive insights. The competition will run for three weeks, with meetings on Saturdays. There are three streams to choose from, and participants can join one, two, or all three:
- Fishery Industry – Exploring Fish Banks (15 April to 6 May 2023)
- Ecological Diversity – Predator-Prey (10 June to 1 July 2023)
- Pollution in Hydrological Systems – Streamco-Flows (12 August to 2 September 2023)
At the end of each stream, judges will award a prize, and an overall prize will be awarded at the end of the competition. We encourage all interested parties to join the competition, expand their modeling skills, and contribute to advancing the field of system dynamics.

Abstract
The standard measure of distance in social networks – average shortest path length – assumes a model of “simple” contagion, in which people only need exposure to influence from one peer to adopt the contagion. However, many social phenomena are “complex” contagions, for which people need exposure to multiple peers before they adopt. In this talk, I argue that the classical measure of path length fails to define network connectedness and node centrality for complex contagions. I provide theoretical and empirical evidence that centrality measures and seeding strategies based on the classical definition of path length frequently misidentify the network features that are most effective for spreading complex contagions. To address these issues, I introduce novel measures of complex path length and complex centrality, which significantly improve the capacity to identify the network structures and central individuals best suited for spreading complex contagions. I validate this theory using empirical data on the spread of a microfinance program in 43 rural Indian villages. Implications for human cultural evolution are discussed.
About the Presenter
Douglas Guilbeault is an Assistant Professor in the Management of Organizations Group at the Haas School of Business.

This investigation extends to how communication dynamics are shaped by various sources of influence, such as organizational culture and social media. His work has appeared in a number of top journals, including Nature Communications, The Proceedings of the National Academy of the Sciences, and Management Science, as well as in popular news outlets, such as The Atlantic, Wired, and The Harvard Business Review. Guilbeault’s work has received top research awards from The International Conference on Computational Social Science, The Cognitive Science Society, and The International Communication Association. He is co-director of the Berkeley-Stanford Computational Culture Lab, and he is a faculty affiliate of the Berkeley Institute for Data Science. He received his Ph.D. from the University of Pennsylvania, where he trained with sociologist Damon Centola in the Network Dynamics Group.

Digital Twin Business Models for Strategy and Operational Management

Digital Twin Business Models for Strategy and Operational Management
In the business field, dynamic models have long been used for simulating long-term plans (3+ years) and medium-term challenges and issues playing out over a few months or quarters. But models have also been used to understand shorter-term phenomena, such as in supply-chain and service-delivery cases. Often, though, the same structures and mechanisms operate over both short and long-time scales. Examples include customer acquisition and retention, and staffing (hiring, promotion, and turnover), and performance-improvement programs. This webinar will show how a single model can capture both short-term and strategic views of the same issue, enabling management to have a coherent long-term plan and to check the impact of that plan on short-term tactical episodes. Taken to the extreme, this approach can get close to offering a “digital twin” of a business or some part of the business, that closely matches its actual performance as well as the development of the wider system that drives that performance. Similar considerations may well apply to plans and challenges in other domains. In this webinar, you will learn:
- The benefits of using System Dynamics to capture both short-term and long-term perspectives of a business issue.
- How to design and implement effective digital twin architectures that can improve organizational performance.
- Real-world examples and case studies of how System Dynamics and digital twins have been used to optimize business performance and drive competitive advantage.

MIT System Dynamics Seminar | First Look at ReThink Health’s Multisolving Investment Model, Part II
Please visit the MIT System Dynamics Seminars page for more information.
You are invited to attend the System Dynamics Seminar being held on Friday, March 10th from 12:30-2:00pm EST in the Jay W. Forrester conference room, E62-450, or via Zoom: https://rippel-org.zoom.us/j/86004993630 (Passcode: 767250)*. Our guest speakers will once again be Jack Homer, Bobby Milstein, and Chris Soderquist (ReThink Health) presenting First Look at ReThink Health’s Multisolving Investment Model, Part II. Lunch will be provided to those attending in person.

Abstract
Picking up where the Thriving Together Theater leaves off, this session will offer a first look at ReThink Health’s next-generation simulation tool, which we call a Multisolving Investment Model. This new tool will help stewards see for themselves WHY certain investments are especially powerful multisolvers in our quest to thrive together (such as efforts to establish racial fairness as a matter of system design; expand belonging and civic muscle; and secure the other vital conditions). As far as we know, this is the first dynamic model to track population-level changes in well-being separately by race/ethnicity, which in turn lets planners see how everyone benefits we invest more among those who have the most to gain.
During this “First Look” session, we will share (1) the origin story of this new model; (2) design features of a working prototype including a dynamic hypothesis, empirical sources, and calibration; as well as (3) insights from initial tests, including illustrative investment scenarios, optimization, and sensitivity to uncertainties. Together, we will discuss ideas for potential use-cases and facilitation options. But this session will largely concentrate on early insights from the new prototype model.
Technical Background: The new Multisolving Investment Model uses the vital conditions framework and builds upon two prior simulation models built to study investment scenarios. Here are background references about those three elements.
