• Analysis of a system
• Specify Relationships and Processes
• To derive Predictions
• To take Decisions

Benefits:

•  It is cheaper to represent a factory layout in diagram is easy than to construct.
•  Used to analyze and experiment with complex situations(which is difficult to construct). 

Kinds of Models:

•      Function
•      Structure
•      Time Reference
•      Generality

Note: Explain every model in detail.
