JAPROSIM: A Java']Java framework for Process Interaction Discrete Event Simulation

In this paper, we discuss various aspects of the design, implementation, and use of JAPROSIM which is a general purpose discrete event simulation framework based on the Java programming language. JAPROSIM is an open source project developed for both academic and industrial purposes. It also merges process-interaction modeling structures with powerful java features in an intelligent way that encourages model simplicity, reusability and automatic statistics collection. Further motivations and aims are discussed. Java multithreading is a powerful built-in mechanism used to coordinate different entities in a coroutine-like mode. The main body of the paper is devoted for explaining the design of the framework in the context of Object Oriented Simulation. Finally, a summary of the proposed framework together with suggestions for improvements are given.
