Optimal Production Stopping and Restarting Times for an EOQ Model with Deteriorating Items
研究了生产、需求和变质率均为时间函数的易变质物品生产库存系统，给出了使单位时间总成本最小的最优生产停止与重启时间，并允许缺货。
AbstractA perishable single item production-inventory system is studied in this paper. The objective is to describe a general model in which the production rate, the product demand rate, and the item deterioration rate are all considered as functions of time, and to discuss the optimal production stopping and restarting times which minimise the total relevant cost per unit time. In the general model, demand shortage is allowed, where some of the demand is lost and the rest is backlogged. Popular models, such as the pure inventory system and the zero shortage system, are shown to be special cases of our model. The conditions for a feasible stationary point to be optimal are given. The simplest cases with constant rates of production, demand and deterioration are discussed and shown as illustrative examples.Keywords: EOQproductiondemanddeteriorationshortage
