Introduction
What Is A Model ?
A Representation of an object, a system, or an idea in some form other than that of the entity itself.
(Shannon)

Introduction
Types of Models:
Physical
(Scale models, prototype plants,…)
Mathematical
(Analytical queueing models, linear programs, simulation)

Introduction
What is Simulation?
A Simulation of a system is the operation of a model, which is a representation of that system.
The model is amenable to manipulation which would be impossible, too expensive, or too impractical to perform on the system which it portrays.
The operation of the model can be studied, and, from this, properties concerning the behavior of the actual system can be inferred.

Introduction
Applications:
Designing and analyzing manufacturing systems
Evaluating H/W and S/W requirements for puter system
Evaluating a new military weapons system or tactics
