A network based approach , called extended petri - nets that represents the design of the supply chain as an abstracted network with " and " and " or " nodes , is presented . based on their substantial disadvantages of linear programming , integer programming , nonlinear programming and genetic algorithm in dealing with a typical supply chain , a constraint based genetic algorithm as part of the extended petri - nets approach is introduced to search for improvements in the design that satisfies the constraints imposed on the system . a prototype testing system is constructed , which is followed by an example together with a description of the small automobile supply chain system implementation
两北丁业人学博十学位论义通过对链式供需链的结构分析，把链式供需链的设计优化转化为多阶段决策问题，在此基础上建立了设计优化模型，并提出前向与后向两种动态规划求解算法；鉴于线性规划、整数规划、非线牲规划以及遗传算法在解决网状供需链设计优化问题时皆存在着不足，本文对petri网进行了改进，提出了扩展petri网的概念，用于把网状供需链抽象为一个具有“与”和“或”变迁节点的网络，并在前人工作的基础上，把基于约束的遗传算法cbga与扩展petri网结合起来，用
