Abstract: To quantify and collect quality management decision, the decision making problem of quality management was described as a group decision making process under uncertainty preference information. A multiattribute group decision making model of quality management was established at first, and its uncertainties of linguistic preference information and weight preference information were analyzed. Dual fuzzy vague set was employed to represent uncertain linguistic preference information, and several basic operators in fuzzy set were introduced to vague set resulting in four decision making functions to eliminate the weight uncertainty. Hence the quantified decision making results of quality management could be collected. Decision making performances of these functions were compared under different weights preference information. Finally, the proposed functions were analyzed and verified by an example.
