A Study on a Measurement Scheme for the Development Goals of the Next Generation EMU

차세대전동차 개발목표에 대한 계량화 방안연구

The development goals of the next generation EMU are to improve the system maintainability, transportation capacity, reliability, passenger service and energy efficiency. In this paper, we propose a measurement scheme for the development goals of the next generation Electric Multiple Unit(EMU). To achieve that, we drew meaningful characteristics for each development goal, which mainly affect effectiveness and performance of vehicle system. Finally, the measurement scheme for the development is obtained by using the characteristics, which could be a numerical values such as maximum velocity, acceleration of the vehicle and so on or subjective values such as a results of surveys from passengers and so on. We expect the proposed measurement scheme will be used to measure the development goals of other similar system as well as the next generation EMU.
