基于广义随机Petri网的贵港生态工业园资源利用率分析

资源利用率是评价生态工业园运行绩效的重要指标,资源高效利用是生态工业园建设的基本要求.本文以广义随机Petri网作为建模工具,以贵港生态工业园作为研究对象,通过构建贵港生态工业园物质循环网络的广义Petri网模型,利用广义随机Petri网模型与马尔科夫链的同构关系,分析了贵港生态工业园关键资源的利用率以及重点加工环节运作效率,指出了贵港生态产业园资源利用过程中有待改善的环节,为贵港生态工业园的优化和改进提供了依据.

Resource utilization analysis of Guigang eco-industry park based on generalized stochastic Petri net

Resource utilization is an important index to evaluate the ecological industrial park, the efficient utiliza-tion of resources is a basis requirement of the ecological industrial park. In this paper, we use the generalized stochastic Petri nets as a modeling tool and Guigang eco-industrial park as the research object to build the stochas-tic Petri net model of substance circulation network of Guigang eco-industrial park. Then, based on the isomorphic relationship between generalized stochastic Petri nets and Markov chain, we analyzed the utilization of main re-sources and the operational efficiency of key processing links. Thus it points out the link that needs to be improved in the process of resource utilization and provide powerful basis for the optimization and improvement of Guigang e-coindustrial park.
