摘要
为克服主观评价的模糊性,确保组合开关力特性评价结果客观、科学、合理,在统计分析的基础上提出一种新的评价方法。确立了汽车转向组合开关力特性的6项评价指标;通过因子分析对转向组合开关的指标体系进行归类和分层,并根据主因子对总目标的贡献率及因子得分系数确定了各级指标的权重值。
A new evaluation method was proposed based on the statistical factor analysis to conquer the illegibility of the subjective evaluation and made it sure that characteristic analysis of the automobile multi-function switch was objective, scientific and reasonable. Firstly, 6 evaluation data of the automobile multi- function switch were confirmed. Secondly, index systems of the automobile multi-function switch were classified and layered,the index weight was figured out and judged by the main factor＇s contribution ratio to the main goal as well as the factor score factor.
