摘要
如何确定定货量及定货时间一直以来都是困扰企业库存管理的一个复杂问题,尤其是在涉及多商品库存问题时,多个变量约束使其愈加复杂。本文在满足资源的约束下建立了多商品混合整数规划模型来优化解决上述两个问题,并比较了固定周期和独立周期两种定货方式下的成本来选择最优订购方式。
How much to order and when to order are the two fundamental issues that long-term puzzle enterprise,especially when it involve multi-product because multi-constraint make it more complex.This paper presents a model to optimizing the two fundamental decisions subject to multiple resource constraint and determining whether a fixed cycle for all product or independent cycle foe each should be used for a lower total cost.
