Scheme evaluation of automobile comprehensive performance based on grey clustering analysis

In view of the deficiency of traditional evaluation method of automobile comprehensive performance, the mathematical optimal solution usually cannot be filtered from several schemes in engineering. This paper introduces the theory of analytic hierarchy process (AHP) and grey clustering analysis. Then seven automobile overall schemes were selected to be evaluated, while six typical performance indicators were selected as evaluation indexes. AHP was used to calculate weight coefficient of each performance index, and grey clustering method was applied to obtain the weighted order of each scheme. The case study showed that the proposed method can evaluate the automobile overall schemes effectively. Seven schemes can be put in order according to the satisfaction degree with grey classification. Thus, the analysis result is practical.
