开发试验中整车性能的加权综合评价及其应用

The Adding Weights Comprehensive Evaluation of Vehicle’s Performance and Its Application in the Development and Test

在汽车的开发过程中,采用加权综合评价方法,对汽车的各项指标(主观评价指标和客观评价指标)进行加权综合评价,将多项评价指标综合成一个能从整体上衡量指标相对优劣的单一指标,即线性加权和Ei。根据Ei值的大小,判断汽车综合指标相对目标车综合指标的优劣。

During the development of vehicle,vehicle＇s various indexes （include subjective evaluation indexes and objective evauation indexes） through adding weights are synthesized a single evaluation index,namely the line adding weights sum Ei,which can weigh an index relatively excellent or inferior from the whole .According as the value of Ei,the excellence or inferiority of vehicle comprehensive index is obtained relativing to the target vehicle.
