 Hi, my name is Jayandran Venkateshwaran, I am a faculty in the industrial engineering and operations research department at IIT Bombay. In this course, we learn about system dynamics modeling, which is a modeling technique to frame, understand and discuss complex issues and problems. In this course, we will learn how to relate various variables by studying a system using causal mapping and developing causal loop diagrams. We will learn how to build stock flow diagrams and simulate the model using computer. We will look at various systems models including business systems, economic systems, environmental systems, new product development, epidemic dynamics and similar models. We will also learn how to analyze models, run policy scenarios and see how to interpret the results using proper methodology.
