The 4th System Dynamics Competition, hosted by the South African System Dynamics Chapter supported by iSee Systems, has concluded. This year we had 50 registrations, 19 different countries, six workshops and six final full submissions. Estee Vermeulen won this year’s System Dynamics Competition. She is part of the Nelson Mandela University (NMMU) in South Africa and holds a PhD in marine planning and management. In the competition, she used system dynamics to evaluate the impact that COVID-19 is having on the tourism industry of the Nelson Mandela bay area. First, she used qualitative causal loop diagrams to capture the multiple mental models of stakeholders living in the system. After that, she constructed a system dynamics simulation in iSee Stella with well-validated COVID-19 and tourism modules. The scenarios explored through the simulation revealed the importance of system dynamics in policy support and decision making. Congratulations, Estee, for winning by showing both the quantitative and qualitative application of system dynamics on a real problem.
