Improving the modeling process

The development of discrete event dynamic simulation (DEDS) models tends to be a time-consuming process. The standard texts used in teaching simulation courses present a structure for developing the models. Unfortunately, the information normally available to the modeler is not necessarily sufficient or accurate enough for the required effort. This results in models that must be redone with increasing levels of detail. This paper reviews the existing methodology for model building in a manufacturing environment and proposes a new method that can considerably shorten model building time
