Application of the structured programming concept of stepwise refinement to modeling is described and developed. Modeling by simulation with GPSS (General Purpose Simulation System) is emphasized, even though the full modeling activity undertaken included analytical and brassboard modeling as well. Stepwise refinement was applied rigorously to the simulation model, and also used for the analytical and brassboard models. The simulation model is described in detail. The network, node and implementation analysis that provided the numerical basis for operation of the model are also described. How the concept of stepwise refinement was applied to the development of the simulation model in GPSS is thoroughly described. Results of the simulation models show how stepwise refinement can maximize useful output with respect to cost and effort invested.
