Research On Comprehensive Benefit Evaluation Of Vehicle Engine Remanufacturing

With the growth of the automobile industry,car ownership increased year by year,Car scrap rate also showed a trend of increasing year by year.At present,China's auto recycling industry is still in its infancy,recycling is simple and crude,and car remanufacturing enterprises is less,advanced technology has not yet mastered.Remanufacturing engine is strictly in accordance with the remanufacturing standard to repair and transform the old engine,the benefits created by remanufacturing has not yet fully demonstrated.This article from the energy consumption,environmental issues,social harm,circular economy and green development point of view,With the purpose of studying the waste engine remanufacturing comprehensive benefits.Mainly include the following aspects:(1)According to China's face of the number of scrap cars surge situation and dismantling the industry is not standardized lead to a series of problems as the background.Introduced the development of re-manufacturing at home and abroad,and analyzed the value of waste engine remanufacturing compared to traditional scrapping.(2)Introducing the process of engine remanufacturing and key parts remanufacturing method.(3)Establishing the Comprehensive benefit evaluation system of vehicle remanufacturing engine,and Conducting a comprehensive and systematic analysis from the resources,economy,environmental protection,social and other four aspects.using expert interval scoring method to quantify analysis of qualitative indicators,obtaining the actual value of the quantitative index,Through the effective coefficient method to determine the standard values for the quantitative indicators,and giving a specific quantitative method.(4)Using AHP to establish the comprehensive benefit index system weight,and finally establishing a multi-level comprehensive judgment mathematical model for the comprehensive benefit of vehicle remanufacturing engine.(5)Taking a Jetta car engine as an example,through consulting literatures and field trips,and Using the index system,obtaining comprehensive benefits of the remanufacturing engine.
