철도차량 경량화를 위한 시스템 성능지표 개발

초록

A technology for weight reduction of a railway vehicle is one of the most important competitiveness for railway industry in the future. To design railway vehicle reduced weight, customer's needs and level of technology should be considered at the beginning of development. Moreover, it can not ignore not only effects of weight reduction but also safety and efficiency during an operation. In this study, we develop system performance indicators to evaluate alternatives of a reduced weight railway vehicle after figuring out customer's needs and technical characteristics about weight reduction. AHP(Analytical Hierarchy Process) and QFD(Quality Function Deployment) are proposed to calculate weights for customer's needs and technical characteristics.
