Guanglong Huang, Zhonghua Yu · Zhongguo jixie gongcheng · 2001
A comprehensive evaluation method is set forth based on evidential reasoning and rough set theory, which is used to deal with multi-level, multi-attribute evaluation problem. This method can utilize subjective information and objective information effectively. Evidential reasoning is used to deal with the information of subjective judgement. At the same time rough set theory is used to obtain objective evaluation knowledge from used data. So the results which conform with engineering practice would be gotten by means of combining them during evaluation. The model and algorithm are introduced. At last, it proves the method is rational and reasonable through the example of evaluating design selection of a gearbox.
