Modular simulation package for product design studies

A simulation package designed to facilitate the creation and execution of large FORTRAN based simulations has been developed by the Xerox Corporation. After a discussion of the model assumptions required to use the package, this paper discusses the key components of the package. This explanation includes the structure of the simulation models and data, the preprocessors used to interface the models to the simulation executive, and the capabilities of the executive. To provide a concrete understanding of the package a simple model is developed, interfaced, and executed.
