In this paper we present an environment for the development of Java‐based discrete event simulations. An integrated approach is taken that combines discrete event semantics with Java and exceeds the expressiveness of discrete event libraries. The environment supports advanced techniques including distributed evaluation with conservative or optimistic event execution using the Time Warp protocol. We present some performance results and discuss the difficulties encountered with Parallel Discrete Event Simulation. © 1998 John Wiley & Sons, Ltd.

In this paper we present an environment for the development of Java-based discrete event simulations. An integrated approach is taken that combines discrete event semantics with Java and exceeds the expressiveness of discrete event libraries. The environment supports advanced techniques including distributed evaluation with conservative or optimistic event execution using the Time Warp protocol. We present some preliminary performance results for the sequential implementation and discuss the difficulties encountered with Parallel Discrete Event Simulation.
