ABSTRACT
This chapter presents material that every engineer should know, and not a complete discussion of everything an engineer should know about modeling. It shows the beginner how to use the information in the book to develop his first simple simulation. Simulation in the present context means exercising the model and obtaining some result. The contrast between modeling and simulation can be expressed as follows: modeling is the development of equations, constraints, and logic rules, while simulation is the exercising of the model. Amplification: Examples of non-controllable factors are: the weather, earth quakes, sun spots, ocean wave phenomena, political climate, etc. Important aspects of all of these can be simulated for use in solving engineering problems. In addition to providing a much more flexible and frequently less expensive vehicle for answering the questions highlighted above, simulation has other benefits.
