Object-Oriented Parallel Discrete Event Simulation

In this chapter we describe a framework for object-oriented parallel simulation. We propose a layered approach which combines the advantages of object-oriented design and programming, with the performance provided by parallel discrete event simulation. The main characteristics of our approach is the modularity promoted by the division into layers and the organization of each layer, the extensive reuse of components through inheritance and composition, the separation and encapsulation of the various issues involved through strict interfaces and well defined abstractions, and the application of the object-oriented design principles in every step of our development. The framework we present allows us to build fast, flexibly and cheaply without sacrificing reliability. The framework is designed to be easily reused and extended. It is also characterized by robustness, efficiency, integrity, and ease of use, it enhances productivity and improves reliability, and it supports rapid prototyping. This framework addresses the need for an integrated environment for parallel simulation by providing a design methodology which structures perception, representation and reasoning in a single integrated entity.
