ABSTRACT

In this study, we determine the optimal manufacturing quantity for an economic production lot-sizing model with a defective rate and preventive maintenance for a manufacturing machine. We investigate the properties of economic manufacturing quantity to minimize expected costs during the production run when a random defective rate for that product is considered using an in-control condition and an out-of-control condition. If a manufacturing machine produces a proportion of defective items which is larger than the lot tolerance percent defective, then a machine shifts from an in-control condition to an out-of-control condition, and it should have a maintenance service to decrease the possibility that it will produce imperfect-quality products. A research model is developed to determine optimal manufacturing quantity and optimal production time when a defective rate and maintenance service are considered. Numerical examples are given for the applicability of the methodology derived in the paper.

具有预防性维护的经济生产批量模型的最优生产策略

摘要

在这项研究中,我们确定了经济生产批量模型的最优制造数量,该模型具有缺陷率和制造机器的预防性维护。我们研究经济生产量的特性生产运行期间,当该产品随机缺陷率使用被认为是降低预期成本在控制条件和外的控制条件。如果制造机器会产生有缺陷的物品的比例比该很多公差不良率较大,则机器位移从在控制条件的外的控制状况,并且应该提供维护服务以减少生产质量不合格产品的可能性。当考虑缺陷率和维修服务时,开发了一种研究模型来确定最佳制造数量和最佳生产时间。数值例子说明了本文方法的适用性。
