Three Phase Simulation in Java

Recent years have seen great interest in the use of Java as a language for developing computer simulations and in the development of methods that utilise the inherently distributed and co-operative nature of the world-wide web. This paper builds on both of these themes and discusses the development of three phase simulation models in Java. The first stage of the work was to use Java simply as a language for model development, much as any other language might be used. The second phase was to use the RMI functions of JDK 1.1 to develop client:server approaches to simulation modelling. Both of these stages are discussed here, with an indication of the problems that were faced and overcome
