공급사슬구성 요소들의 효율측정과 향상에 관한 연구

Abstract

The relationship between a manufacturing firm and its supplier is regarded as one of the most important issues when the partnership of organization is considered. Especially the poor relationship between linked components in a supply chain results in excessive delays and ultimately leads to poor customer service. In this paper, we consider a multi-factor, multi-cause decision making problem of supply chain. And we show how to measure the operational efficiency of the components in supply chain and also how to improve the efficiency of each component and whole supply chain. As a methodology, Data Envelopment Analysis (DEA) is adopted to measure the efficiency by considering weight factors such as flexibility, information sharing, logistics level, etc. DEA has been widely applied to address various decision analysis problems due to its usefulness in evaluating multi-criterion systems and providing improvement targets for such systems. The proposed algorithm allows whole supply chain to achieve the improved efficiency.
