一种基于秩和比-熵权法的电动汽车综合评价方法

A comprehensive evaluation method for electric vehicles based on rank sum ratio-entropy weight method

本文通过充分调研,获得了电动汽车的主要评价指标和可用数据。然后提出了一种基于秩和比-熵权法的电动汽车评价方法,使用熵权赋值法(EWM)对传统的秩和比法(RSR)进行了改进,能够计及电动汽车多方面的指标数据进行综合评价,充分考虑客观因素对指标进行赋权,最终得出各类车型的综合排名,为电动汽车的评价和选型提供了可靠依据。

This paper obtains the main evaluation indexes and available data of electric vehicles through full investigation.Then,an electric vehicle evaluation method based on rank sum ratio and entropy weight method is proposed.The entropy weight assignment method(EWM)is used to improve the traditional rank sum ratio method(RSR),which can comprehensively evaluate various indicator data of electric vehicles and give weight to indicators with full consideration of objective factors.Finally,the comprehensive ranking of various models is obtained.It provides a reliable basis for the evaluation and selection of electric vehicles.
