碩士 === 健行科技大學 === 工業管理系碩士班 === 104 === For certain types of merchandise, customer’s demand rates could be affected by inventory levels. This study considers two inventory models where the demand rate is correlated with the stock level. The first model discusses the inventory model for retailer’s warehouse and store. We assume that the goods are stored by the retailer’s warehouse in a larger quantity, and then are shipped to the store for sale in a less quantity. The second model investigates the distribution problem for wholesaler and retailer. The wholesaler conducts an inspection process for goods to eliminate defective items. Subsequently, the prefect items are delivered to the retailer. For the two models, the optimal inventory policies with separate and joint decision-makings are discussed, respectively. We derive the optimal policies by minimizing the total inventory cost or maximizing the total profit. Moreover, the solution procedures to solve the two models are proposed. Finally, numerical examples are provided to illustrate solution steps, and show how to derive the optimal number of delivery and the optimal delivery quantity. The management insights from this study are suggested to managers determining inventory policies.
