摘要:

订货提前期是供应链管理中的基础性概念,对它的研究是近年来颇受关注的课题。Petri 网以其兼备图形化的描述方式和严格的数学定义的特点而成为很好的复杂物流系统的建模工具。论文给出广义随机Petri网方法的定义,并应用于计算订货提前期和评价提前期中各种活动的效率,对确定提前期具有一定的指导意义。

关键词: 广义随机Petri网, 供应链, 马尔可夫链, 提前期

Abstract:

Lead time is an elementary factor in supply chain management, which has become a focus of recent research. Petri net is a quite good modeling technique for complex logistics systems, which is characterized by visual tools and strict math basis. This paper gives defination of the Generalized Stochastic Petri Net, and apply GSPN method to caculate the supply chian lead time and to analyze the perfomances of different activities derived fom the purchase process.

Key words: generalized stochastic petri net, supply chain, markov chain, lead time
