Research on comprehensive evaluation of six “properties” for equipment products incorporating correlate indexes

Abstract

Abstract The six “properties” for equipment products are critical indexes to improve the quality of equipment development and batch production. In view of current difficulties of auditing six “properties” and putting qualitative or quantitative evaluation into practices, this paper analyses interactive characteristics of six “properties” and organically integrates them based on the VIKOR method. Firstly, the indexes and connotation of six “properties” for equipment products have been elaborated. Secondly, specific relationship among six “properties” is analysed and their interactive coefficients are depicted as two additive fuzzy measures. Thirdly, the effect of interactive coefficient among six “properties” is analysed on group utility and individual regret in the VIKOR method, and specific decision-making steps based on the VIKOR method are also proposed. Finally, two illustrative cases show the differences of multiple indexes decision results under two kinds of conditions and the feasibility and effectiveness of the proposed methods.
