摘要
研究不确定市场条件下如何建立农产品供应链模型,分析农产品供应链库存和利润变化情况。针对目前的Petri网着重于分析托肯数量与变迁时延的关系,为了改善Petri网在分析农产品供应链系统中不确定市场环境对库存和利润的影响方面的不足,将在带有价格信息的着色Petri网(PCPN)和流体随机Petri网(FSPN)进行结合,提出使用扩展着色广义随机Petri网(ECGSPN)的理论工具建立农产品供应链模型,来分析不确定市场环境对农产品供应链利润和库存变化的影响,得出不确定市场环境与农产品供应链利润和库存变化的定性关系。
The paper mainly focus on how to establish a model to analysis developing trends of profit and stocks of supply chain on agricultural products on agricultural products under uncertain market circumstance.The Petri net model available concentrated on analysis relationship between number of tokens and time delay of transitions.In order to solve the deficiency of analyzing developing trends of profit and stocks of supply chain on agricultural products under uncertain circumstance,a model based on extended colored general stochastic Petri nets(ECGSPN) was proposed in virtue of PCPN(price colored Petri net) and FSPN(fluid stochastic Petri nets).
