【摘要】 以流程为核心对供应链进行再造是优化供应链的重要措施,而对流程进行量化的分析评价是近年来流程再造研究的热点.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目前流行的业务流程建模工具.给出随机时间Petri网的定义及其性能评价方法之后,对第三方物流业务流程进行建模和分析.更多还原

【Abstract】 Reengineering supply chains based on process is the important means to optimize supply chains.People are paying more and more attention to quantificational researches of Business Process Reengineering.Petri net becomes a popular business process model tool,because it has both description language for model and strict mathematical definitions.Stochastic Timed Petri nets are a powerful modeling formalism,widely used for the performance and dependability evaluation of systems.But Stochastic Timed Petri nets are mainly used in manufacturing industry.The study on modeling process of supply chains is little up to now.So this article describe the definition of Stochastic Timed Petri nets and the method of performance analysis firstly,then modeling logistics business process and analysis will be given.更多还原
