Algorithm for priority of fuzzy complementary judgement matrix

This paper gives an analysis for the parameters in the transformation formulas of the fuzzy consistent judgement matrix and presents a formula for priority of fuzzy complementary judgement matrix, and extends it to group decision making. The priority formula not only contains the desired properties of the fuzzy consistent complementary judgement matrix and most judgement information, but also needs less time in calculation and is simple, reasonable and effective. It can bring people great convenience in practical applications. Finally, a numerical example is given.
