Course Objectives:
1. Provides students with concept of "System Thinking" and system analysis using simulation model as a tool.
2. Provides step-by-step of model (mechanistic type) construction procedure.
3. Encorage each student to apply modeling technique in solving real-word problems, dicision making and policy analysis.
