Object oriented modeling with SIMPLE++

Object orientation has become a major competitive factor in information technology. Reasons for this are the control of complexity, increased quality and possible reuse of modules. The discrete event simulation system SIMPLE++ being presented in this paper brings these advantages to the simulation user. SLMPLE++ is a general purpose system for the object oriented, graphical, and integrated modeling, simulation, and animation of systems and business processes. Models are built with objects from a class library containing predefined building blocks. User defined classes can be created in an integrated way, allowing the modeling environment to be tailored to different application areas. The class structure, inheritance and unlimited number of hierarchical levels lead to a significant increase of productivity in building, changing, and maintaining models. The concept and benefits of object oriented modeling will be illustrated in the following. In addition to the modeling environment, the support for validation, simulation, and evaluation of results is covered. Also, the integration of simulation models into existing IT solutions as well as application specific object libraries are explained
