摘　　要：论文首先将模糊随机变量扩展为混合随机变量,并用来描述不确定需求。然后对多级单周期库存系统在模糊随机和混合随机需求环境下的优化与协调问题作了研究,提出了通过集成库存管理使库存系统整体收益期望值最大化的优化模型和协调合作伙伴利益的数量折扣契约模型,并根据遗传算法理论和计算机模拟技术设计了求解模型的智能算法。最后通过实例对模型进行了仿真分析。This paper first puts forward the concept of mixture radon variable,and used for description of uncertain demand.Then make search for multi-echelon and short period inventory system optimization problem based on fuzzy random or mixture random demand expected value theory.In paper formulate an inventory system optimization model which make whole profit biggest through integrated inventory management and a quantity discount contract model based on coordinating cooperative partner benefit,and put forward an intelligence algorithm based on genetic algorithm combined with computer mixture random variables simulation.Finally,a data simulation analysis is made.
