建立了柔性供应链战略层优化模型，考虑了生产和分销的柔性，确定了不同柔性条件下供应链的最优结构和物流。对农机公司柔性供应链的仿真表明，供应链柔性的增大是有限度的。以后的工作是建立供应链作业层的优化模型，进而把战略层和作业层联合进行优化，确定供应链的最佳物流过程。

Optimal Model of Flexible Supply Chain and its Applications
Zhang Cuihua Huang Xiaoyuan
Abstract Flexible supply chain’s optimization model is studied and an optimization model for supply chain is set up with regard to all constraints on production and distribution..Evolutionary planning(EP) is applied to optimize an Agricultural Machines Corp.’flexible SC model and sensitive analysis is made. Results indicate that the model incorporates production and distribution uncertainties using flexibility index and can evaluate SC’operation more comprehensively.It is helpful to design efficient and effective supply chain with enough flexibility.For mixed-integar linear model with a lot of datas ,EP is proper.Keywords flexible supply chain optimal model EP
