This course introduces system dynamics modeling for the analysis of business decisions with a focus on industrial, service and public policy applications, particularly those decisions forced by structural changes, policies and strategies that affect how the system behaves. It provides the student with the conceptual tools to understand the structure and dynamics of complex systems. This rigorous method will be used to model decision support systems where space and time can be compressed and slowed for the decision maker to experience the long-term side effects of decisions.
