  2. Tahapan • CONCEPTUALIZATION • Define the purpose of the model • Define the model boundary and identify key variables • Describe the behavior or draw the reference modes of the key • variables • Diagram the basic mechanisms, the feedback loops, of the • system • FORMULATION • Convert feedback diagrams to level and rate equations • Estimate and select parameter values • TESTING • Simulate the model and test the dynamic hypothesis • Test the model’s assumptions • Test model behavior and sensitivity to perturbations • IMPLEMENTATION • Test the model’s response to different policies • Translate study insights to an accessible form

  3. Purposes • The purpose of a model usually falls into one of the following categories: • to clarify knowledge and understanding of the system • to discover policies that will improve system behavior • to capture mental models and serve as a communication and unifying medium.
