摘要
建立了固定计划期上的变质性产品库存模型,其中利用折现现金流法计算各项成本,需求考虑通货膨胀的影响,允许缺货且短缺量部分拖后.证明了系统总费用最小的必要条件,然后简化了模型,并给出了有效的求解方法.最后,用数值例子和灵敏度分析对模型进行了说明.
An inventory lot-sizing model is developed for deteriorating items over a fixed planning horizon, where the Discounted Cash Flow approach is used to fully recognize the financial implication of the opportunity cost and out-of-pocket costs. The demand rate is assumed to be influenced by inflation. Shortages are allowed with partial backlogging. The necessary condition which minimizes the total system cost is presented. Then the model is simplified,and an effective solution procedure is provided. Finally,a numerical example and sensitivity analysis are shown to illustrate the model.
