碩士 === 中原大學 === 工業工程研究所 === 96 === Market competition is becoming more intense in this rapid developing global economy. Effective inventory control can improve utility to satisfy market demand. In a two echelon supply chain, the manufacture and the retail usually try to reduce their cost, without considering the other party. In order to reduce supply chain cost, companies should collaborate with the other members in the supply chain. In recent years, Taiwan's economy is not stable, and inflation result is price increase, therefore effective use of warehouse space and improved stocking strategy become critical issues to be investigated. In this research, deteriorating items under two level supply chain is investigated. Deterioration rate is assumed to be exponential distributed. A two warehouse inventory model with a delay in payment is developed. We consider shortage, time value of money and discounted cash flow in the problem analysis. The objective of this research paper is to develop an optimal collaborative economic lot size policy. Finally, GA tool in the MatLab software is used to solve the problem. Maple and Excel software are used in the numerical analysis. A numerical example and sensitivity analysis are presented to illustrate the theory.
