Multi-level in Fuzzy evaluation of the development analysis of electric vehicle

In view of overall strategies for the development of Electric Vehicles and their internal conditions, the complex engineering designs of their promotions often involves some parameters' determination such as research and development, market, battery cost performance, motor cost performance, some quality indicators of mutual restraints and many other complex influential factors are. In order to obtain satisfactory products, the evaluation indicator of Electric Vehicle development should be analyzed and evaluated. This paper constructs evaluation index systems of Electric Vehicles development and determines the evaluation index and weight reasonably by multi-level and multi-objective fuzzy comprehensive evaluation methods. And by transforming complicated multiple evaluations into simple quantitative evaluations, it provides a scientific evaluation method for improving the overall evaluations of electric vehicle development.
