| Summary: | 碩士 === 國立東華大學 === 全球運籌管理研究所 === 96 === This thesis studies a manufacturer-retailer supply chain with multiple shipments and production learning effect. In the system, unit production time of the manufacturer declines as production volume increases due to learning. The learning effect is not transmitted from one production setup to the next. The demand of the system occurs only at the retailer with a constant rate. The cost structure of the system includes the costs of production setup and holding, and the cost of shipment at the manufacturer, and the costs of holding and ordering, and the cost of loss of production flexibility and receving cost at the retailer. To operate the system, this research needs to determine the following three variables: a) the order lot size of the retailer, b) the number of shipments within a lot size and c) the production lot size of the supplier.
In purchasing market, the retailer and manufacturer often have adversarial relationship. This controversial situation may lead to a series of decisions against each other. The optimal strategy may need to consider the performance of the overall system. Hence, the criteria of decisions in this study are classified into three scenarios including the system dominated by the retailer, or dominated by the manufacturer, and the system integrated by both parties. The objective of this thesis is to minimize the total cost based on each of three scenarios.
A sensitivity analysis is conducted based on numerical experiments. The results of the numerical experiments show that the effects of learning will increase the total cost of the supply chain as well as the lot size of a shipment. If the system pursues a manner of Just-in-Time between the manufacturer and retailer, a lower of the shipment lot size can be reached by lower costs of shipment and receiving.
