Development and Experimentation of PDES-based Analytic Simulation

Abstract

Parallel-discrete-event-simulation-based analytic simulation (PAS) is an effective approach to studycomplex issues and analyze complex systems.But the complexity and high demand for credibility of PAS make its development and experimentation quite different from traditional information systems. Firstly, this article briefly introduces analytic simulation concept and the difference with training simulation. And then five computational characteristics which cause the huge computation demand are summarized: multi-sample, multi-entity, as fast as possible, synchronization for constraint of causality and complex model calculation. According to these characteristics, a "Sample, Entity, Model" three-level-Parallelization solution(SEMP) is introduced for PAS.The solution can be used to fully exploit the parallelization of PAS and utilize the computing resources in different levels, which is able to meet the growing computation demand of PAS. Finally, in order to improve the development efficiency and credibility of PAS application, based on the accumulation of several years' R&D, we conclude a summary of development and experimentation flow of PAS, and propose four additional VV&A principles to improve credibility, which can be used to guide the development and experimentation of PDES-based analytic simulation.
