论文摘要
本文通过使用三角模糊数字，在模糊环境中收到修复性批处理和订单重叠，为不完美的物品提供了库存模型。假定通过筛选确定的不完美项目分为废料或可重修的项目。可重新工作的物品保存在商店中，直到收到下一个物品为止。之后，将项目返回给供应商进行重新设计。此外，采用购买费用的折扣是从供应商向买方提供的合作提议，以弥补购买者产生的所有额外的持有费用。返工过程是无错误的。采用订单重叠计划，以便允许供应商使用先前的货物来满足检查期的需求。在模糊模型中，采用分级平均积分方法来解剖模型并确定其利润函数和最佳策略的近似。在此过程中，渲染数值示例以表示模型行为，并最终提出了灵敏度分析。
This paper presents an inventory model for imperfect quality items with receiving a reparative batch and order overlapping in a fuzzy environment by employing triangular fuzzy numbers. It is assumed that the imperfect items identified by screening are divided into either scrap or reworkable items. The reworkable items are kept in store until the next items are received. Afterward, the items are returned to the supplier to be reworked. Also, a discount on the purchasing cost is employed as an offer of cooperation from a supplier to a buyer to compensate for all additional holding costs incurred to the buyer. The rework process is error-free. An order overlapping scheme is employed so that the vendor is allowed to use the previous shipment to meet the demand by the inspection period. In the fuzzy model, the graded mean integration method is taken to defuzzify the model and determine its approximation of a profit function and optimal policy. In doing so, numerical examples are rendered to represent the model behavior and, eventually, the sensitivity analysis is presented.
