Abstract: The traditional concept evaluation approaches based on multi-criteria decision-making decided the criteria according to experts subjective decisions,and the ranking result could hardly judge the quality of concept intuitively.To deal with the problem,a concept evaluation approach combined the advantage of information axiom that could quantify the design degree of criteria and the advantage of cloud model that could transform the quantitative information was proposed based on information axiom and cloud model.Compared with the fuzzy set method,rough set did not require a priori information and could objectively deal with the fuzzy and uncertain information of evaluation criteria.A concept evaluation approach based on rough information axiom was proposed.The information content of concept evaluation criteria deemed as cloud droplets were used to transform information content into qualitative concept evaluation with backward cloud model,and then the concept was analyzed by cloud digital feature.A case of concept evaluation for loader was given out to demonstrate the effectiveness of the proposed approach.
