摘　　要：研究了供应链环境下的批量生产计划问题。在确定需求的基础上,建立了模糊需求下批量生产优化模型,并将其转化为模糊机会约束规划模型。用清晰等价类对其进行清晰化处理,目标函数是单位时间供应链总成本最优,并将模糊模拟技术引入遗传算法对模型进行求解。数值实例验证了其有效性。The lot sizing production planning in supply chain management is studied. Based on the definite maket demand,a model minimized average cost per time unit is considered and translated into a programming model with the fuzzy chance constrains. Then it is made difuzzy with the equivalance classes of difinite. The fuzzy simulation are introduced into GA to calculate the mode. The simulation examples indicate FS-GA＇ s validity.
