Abstract: To evaluate the vagueness of information in quality function configuration effectively, a priority determination approach of engineering characteristics based on multi-format information was proposed. Due to the easy acquirement and high accuracy of evaluation information for engineering characteristics'self correlation and correlative relationship between customer requirements and engineering characteristics, the utility values were used to judge.The judgment information and the weights of estimators were integrated by using weight arithmetic average operator, and the relation importance of every engineering characteristic were calculated on the combination of the group relationship values matrix, the correlation measures matrix and the finally importance ratings of customer requirements. Owning to the uncertainty of competitive performance analysis, the competition potential of each engineering characteristics with various forms was introduced. The transformation functions were used to unify the multi-format information into complementary judgment matrix, and the competition potential coefficients of engineering characteristics were obtained by using normalizing rank aggregation method. Through integrating relation importance with competition potential coefficient, the comprehensive priority of engineering characteristics was determined. The feasibility and validity of this approach was illustrated with a real-world case of PE jaw crusher.
