Research on Weight Calculation for Requirement Indexes of Marine Shaft System Based on Fuzzy Analytic Hierarchy Process

Pointed to the problem that fuzzy information was usually ignored in order to simplify Quality Function Deployment modeling process which make the decision deviate from scientific and reasonable result, fuzzy analytic hierarchy process was proposed to apply to weight calculation for requirement indexes of marine shaft system. Furthermore, construction method of fuzzy complementary matrix and weight vector defuzzification method for requirement indexes were deeply studied. Finally weight calculation of requirement indexes for a marine shaft system was studied as a case, which indicated that the method is feasible.
