3. Modeling and simulation

3.1 Definition

Prior to any application of modeling and simulation, it is necessary to define what these concepts cover. According to Vaughan , modeling refers to setting up mathematical equations to describe the system of interest, assembling appropriate input data and incorporating these equations and input data into a computer program. This model must simplify complex phenomena. Simulation, on the other hand, is restricted to using the model within its field of validity to perform numerical experiments, under controlled conditions,...
