GPSS/H is a tried-and-true simulation tool whose user base, both commercial and academic, continues to grow despite the presence of many “new” simulation technology trends. The process-interaction world view combines with the advanced features available in GPSS/H to make one of the most powerful and flexible tools available, capable of handling the largest simulation projects with ease, yet still providing exceptionally high performance. The following sections provide an overview of GPSS/H and its process-interaction world view, a discussion of model-building interfaces including the advantages and pitfalls of graphical modeling environments, and a summary of advanced and recentlyadded GPSS/H features. Finally, the special-purpose simulator is discussed, along with features of GPSS/H which make it ideal for use as the engine in such a simulator.
