Abstract

We describe a prototype implementation of a model management system (MMS) for discrete-event simulation models. The development platform is a relational Database Management System (DBMS) installed on a desktop computer. The conceptual foundation for this MMS is Structured Modeling (SM) and Extended Structured Modeling (ESM). Using the SM and ESM frameworks makes it possible to take an integrated approach to representing and managing both models and data. It also makes possible the use of various DBMS functions to aid in the implementation of MMS functions. In effect, the MMS is constructed as a database application. The user interface to the MMS was implemented using application the Forms and Menus Facilities of the DBMS. A variety of reports documenting the model are generated using the query language of the DBMS. Most important perhaps is the code generation procedure, a complex query procedure that produces SIMSCRIPT II.5 code for simulating the model from the model representation stored in the database.
