摘要
针对随机需求市场环境下企业利润变化分析的需要,在PCPN的基础上,与GSPN进行有机结合,本文提出广义随机价格着色Petri网,讨论了广义随机价格着色Petri网(GSPCPN)的变迁步规则,给出了不确定市场环境下供应链的模型。以一个不确定市场条件下供应链流程为实例演示了其应用,结论表明:广义随机价格着色Petri网对于解决供应链不确定市场环境下的利润和库存变化分析问题是有效的。
The paper mainly focuses on how to establish a model to analyse the development trends of profit and stocks of the supply chain under uncertain market circumstances. In order to solve the deficiency of analyzing developing the trends of profit and stocks of the supply chain under uncertain circumstances, a model based on the general stochastic price color Petri nets （GSPCPN） is proposed in virtue of PCPN （price colored Petri net ） and GSPN（General stochastic Petri nets）. The transition step rule of PCPN is defined. A supply chain process case is demonstrated to show how to apply the GSPCPN. The conclusion is that GSPCPN does well in solving the stock and profit analysis problem in the supply chain modeling under uncertain market circumstances.
