基于组合模型的二手车完损度分析

以二手车技术评估为方向,以给予顾客选车作参考为目的,从车身外观、发动机、车内及电动设备、底盘、车辆性能等5个方面,建立了基于静态检查、动态检查和仪器检查3个主要鉴定方法的二手车完损度评价指标体系。应用熵值法确定指标的权重,构建以灰色关联度理论进行综合分析的二手车完损度评价模型,并以实例进行二手车完损度示范评价。结果表明:该评价模型理论简捷、方法简便、可操作性强,具有较好的应用价值,可为汽车的报废标准的完善提供参考。

Analysis of Damage Degree of Vehicle Based on Assemble Model

Based on used vehicle technology assessment,the paper aims to give reference for customer.The synthetic evaluation system of second-hand car depends on static check,dynamic check and instrument check,including five elements: appearance,engine,inner and electric equipment,performance.Entropy method was employed to determine the weight of indexes;an evaluation model of the damaged degree of used vehicle was built based on Grey relation degree theory.The results show that the theory of evaluation model is succinct,convinient and operable.Therefore it is valuable and could provide references for revising the standard of scrapped car.
