广义随机Petri网在生态产业园区性能分析中的应用

摘要

This paper applied the generalized stochastic Petri nets(GSNP) to model eco-industrial park for describing and evaluating quantitatively planning scheme.It established the corresponding Markov chain based on isomorphic relation between GSPN and Markov chain.And obtained some main performance indices with Markov chain and corresponding mathematics method.These main performance indices included throughput, executing time, utilization rate of the key resources and operation efficiency of the key processing links.Finally, diagnosed the problems in planning scheme, and the results could be used as reference for evaluation and improvement of eeo-industrial park' planning scheme.%为了对生态产业园区规划方案进行定量描述和评价,利用基于广义随机Petri网的建模分析方法,根据广义随机Petri网模型与马尔可夫链的同构关系,得到生态产业园区的Petri网模型和马尔可夫链模型.并通过马尔可夫链理论与相关数学方法,得到生态产业园区规划方案的吞吐性能、时间性能以及关键资源利用率和重点加工环节运作效率等性能指标,诊断出现有规划中存在的问题,为生态产业园区规划方案的评价和改进提供了一个思路.
