Evaluation Schemes for Development Goals of the AEMU

초록

In this paper, we proposed an evaluation scheme with objective and logical manner for development goal of the AEMU, which is a new concept of urban transit system. The development goals of the AEMU are to improve the system maintainability, reliability and energy efficiency by 20 percent, and transportation capacity and environmental friendship by 10 percent, and passenger’s service by 30 percent. To prove each development goals, we derived possible meaningful characteristics, which can mainly affect the evaluation result, for each goal, and designed the numerical expression model with objective manner which can include all of impact factors, then defined input parameters and weight factors for each impact factor. The calculated results of the expressions may be a kind of numerical values, such as a number of people, amount of money, and so on. To prove the development goal of AEMU, we have to carry out the same process for the conventional EMU. Then, we compared the results of AEMU with that of conventional EMU for each goal, and, finally, expressed the comparison result as a kind of percentage. We expect the proposed measurement scheme will be used to measure the development goal of other system as well as the AEMU.
