耐烦期有限的供应商管理库存模型

在无短缺量拖后或短缺量完全拖后的VMI模型基础上,进一步考虑在仓库出空期间,顾客存在耐烦期和不耐烦期的情况.耐烦期内顾客愿意等待自己的订货得到满足,而不耐烦期间会丢失部分顾客,对短缺拖后成本的计算进行了修正,并将变质成本加入总成本中,建立了包括一个供应商和多个订货商,从原材料到产成品且考虑最终产品变质的供应商管理库存(VMI,Vendor-Managed Inventory)模型,运用Mathematic 4.1版软件进行数值仿真和灵敏度分析,表明最优解存在且对VMI库存系统的各种参数具有不同的敏感性.

Vendor-managed Inventory Model with Time-limited Free Back- orders

Based on the VMI model with completely backlogging and without backlogging, the authors develop a new VMI model with partial backlogging and time-limited free back-orders, including a single vendor and multiple buyers. This model modifies the backlogging cost proposed by some documents, and takes account of the deterioration cost in the analysis of the total inventory cost. A numerical example and sensitivity analysis are presented to illustrate the model. The theoretical evidence is provided for VMI system to make management decision.
