MODSIM II is an object-oriented discrete event simulation language featuring extensive run-time libraries, graphical user interface and results presentation tools, database access, and hooks to HLA. This tutorial introduces the MODSIM III language. It shows how MODSIM III's simulation "world view" together with its object-oriented architecture, built in graphics, and interoperability contribute to successful simulation application building. 1 WHAT IS MODSIM III? MODSIM III is a complete development environment. The Simulation Layer, Graphics Editor, Compilation Manager, and the Interactive Debugger provide the environment required for the successful development of advanced models. MODSIM III runs on Windows 95, 98, and NT as well as Unix platforms. MODSIM III is an object-oriented discrete event simulation language. It offers extensive run-time libraries to help the developer create commercial quality simulation applications quickly. These libraries include modules focu...
