of a real-world process or system over time. Whether done by hand or on a computer‚ simulation involves the generation of an artificial history of a system‚ and the observation of that artificial history to draw inferences concerning the operating characteristics of the real system. The behavior of a system as it evolves over time is studied by developing a simulation model. This model usually takes the form of a set of assumptions concerning the operation of the system. These assumptions are expressed
