This class explores the proper use of graphical functions and best practices for defining them.ĭynamic Modeling I Class 1: Model Formulations Each graphical function stands inįor more detailed model structure that does not need to be explicitly modeled, thus simplifying your model structure. Graphical functions define relationships between variables at an aggregate level. We will explore thisĪrchetype in depth and look at examples of its use in several application areas. The Limits to Growth archetype is an important coupled feedback system that recurs with surprising regularity. Each stage of this process will be presented using a specific modeling problem as an example. Successful model development requires a disciplined approach, starting from the reference mode and moving through model validation and In this class, we will explore some of the most common substructures that include multiple feedback loops. While simple feedback can lead to very interesting behavior, the systems around us are composed of several interlocking feedback loops. Introduction to Dynamic Modeling II Class 1: Combining Feedback Simple stock-flow structures with feedback are explored. The first of these in great detail, showing the importance of graphs for defining the boundaries of your model.Īdding feedback to models closes the loop and creates a system whose structure determines its behavior. When using Systems Thinking, we are particularly concerned with behavior over time and feedback. Using the concepts discussed in this session, we will begin building basic models. This class will introduce simple – yet important – Stocks and flows are the basic building blocks of all Systems Thinking models. This class will review types and uses of models, as well as essential Systems Thinking skills such as operational thinking. Introduction to Dynamic Modeling I Class 1: Introduction to Models
