基于广义随机Petri网的装备维修保障建模与分析

Modeling and Analysis of Equipment Maintenance Support Systems Based on Generalized Stochastic Petri Net

信息化条件下,传统的装备维修保障已经不适应现代战场的需要。通过BPR(Business Process Reengineering)可以有效提高其效率,而对改造效果的评价成为是否实施BPR的关键问题。研究了如何利用广义随机Petri网对装备维修保障流程进行建模,对模型进行化简求出可达图构建与模型同构的马尔科夫链(MC),并基于MC的稳定状态概率进行所要求的系统性能分析,获得流程系统的主要性能指标可以为重新设计业务流程提供支持和依据。

Under the information-based condition,the traditional equipment maintenance support system has no longer adapted to the demand of the modern battlefield.Effectively raise its efficiency with BPR,but evaluation of BPR becomes to the key problem.Conduct research on how to utilize generalized stochastic Petri net to model equipment maintenance support system,and simplify the model to get the MC that has the same consistency with the model,and obtain main performance index of the process system through isomorphic Markov chain,providing basis and support for redesigning the process.
