2、库存管理基本理论的基础上,研究了需求随机、提前期不确定的供应链环境下的库存控制系统建模。分析了各企业所面临的需求情况和提前期状况,建立各个成本中心的库存模型;以成本和时间最小化作为优化目标,具有一定的约束条件,构建了供应链分销系统二级库存优化的多目标模型。通过模型求解方法研究,将多目标函数采用加权法转化为单目标函数;选择用遗传算法对模型进行求解,并进行了库存优化模型遗传算法设计。最后,通过一个数值算例证明了该模型的可行性。(空1行,小四号)关键词:供应链,分销网络,成本,库存优化,遗传算法ABSTRACT(空2行,小四号)Distribution System is the important

The amount must be controlled both in preconditon of reaching the serving level and by minimizing the cost of inventory.After analyzing the background and significance of inventory management under the environment of the supply chain, this disserta
