基于分层Petri网的敏捷供应链建模与分析

基于Petri网系统理论,采用分层分析的方法,将供应链抽象出顶层和底层模块,将顶层模块细化,形成底层模块,并生成与各层次相对应的状态图.根据状态图抽象出其中的库所、变迁等变量,形成对应的Petri网.利用Petri网理论对此供应链系统进行静态结构分析和动态行为分析,最终实现供应链上各节点企业的整体集成和协调控制.子网中应用CPRF流程生成订单的思想,构造订单生成子网模块,产品生产子网模块及信息采集子网模块,整合出整个供应链的子网系统.最后,对系统的鲁棒性和反应敏捷度作综合分析,构造了可达树,并对所建模型的正确性和可达性进行分析.

Modeling and Analysis of Agile Supply Chain Based on Hierarchical Petri Net

Based on Petri net systems theory,the supply chain was abstracted to top and bottom modules using stratified analysis,the top-level module was refined into bottom-level module,then the state diagram was built corresponding to various levels.Based on the state diagram,place,transition and so on was abstracted to format the corresponding Petri net.The static structure and dynamic behavior of this supply chain system was analysised by Petri net to make all nodes in the supply chain integration and coordination eventually.Subnet included the module of order generation inspired by the thought of CPRF,the module of production and the module of information collection.Finally the comprehensive analysis of robustness and Agility of the system was made and the reachability tree to verify the accuracy and accessibility of the system was constructed.
