Scaling, hierarchical modeling, and reuse in an object-oriented modeling and simulation system

Three useful modeling techniques for specifying discrete event simulation models are discussed. Hierarchical model specification provides for model specification at different levels of abstraction. Scaling of model elements provides for the combination of similarly structured and parallel operating model elements into arrays of both fixed and dynamic sizes. Reuse of model elements allows for the repeated use of model element specifications. The Hierarchical Control Flow Graph Model paradigm is used to demonstrate the techniques discussed.
