碩士 / 朝陽科技大學 / 工業工程與管理系碩士班 / 99 / This research develops two mathematical models with buyer’s inventory holding costs under the imperfect production system. They are (1) EPQ model with (n+1) deliveries strategy to multiple-buyers. This model also assumes have failure ratio in rework of defective items. (2) Multi-item production system with scrap and multi-delivery policy under rotation cycle policy. Traditional EPQ model assumes that the demand for the shipment is continuous, but it is not realistic. Therefore, the delivery of products often adopts multiple fixed quantity shipments. Total costs include manufacturer and buyer of inventory costs, and the objective is to minimize the total costs. Optimal lot size and best delivery policy are derived for Model 1. Optimal production time and number of deliveries are obtained for Model 2. Finally, numerical examples are provided for validation and sensitivity analysis demonstrates its applicability.
