Multi-level In Fuzzy Evaluation Of The Development Analysis And Research Of Electric Vehicle

Modern human economy has a rapidly development and mainly depend on oilresources that becomes more and more valuable as a non-renewable resources. Oilresources has become a bottleneck in the development of the world economy. Research onelectric cars should not just be limited to the technology of electric vehicles, as importantas the key factors that restrict the development of electric vehicles.On the basis of the analysis and understanding of the current situation of thedevelopment of electric vehicles, key technologies, market factors, describe main keyfactor restricted the development of electric vehicle, the short comings and trend forcurrent stage in electric vehicle development. Fully discuss restricted key technologyfactors, mainly show in finished cars design，body design and battery technology and soon.We start from the macro point of view to analyze the factors that restrict thedevelopment of electric vehicles, build the electric vehicle evaluation index system bydetermining maximized restricted evaluation factors. Use a series of influential factors inthe evaluation system to calculate weight of evaluation factors. Use a multilevel,multi-objective fuzzy comprehensive evaluation method to build a comprehensiveevaluation model for index of restricting electric vehicle development. Solve the judgmentfuzziness and uncertainty of product development in electric vehicle, provide the scientifictheoretical basis for enterprises, scientific research institutions, government, consumers,investors and provide practical advice for the development of the electric vehicle industry.
