Projection Model of Intuitionistic Fuzzy Multiple Attribution Decision Making about Preventive Maintenance Modes in RCMA

In order to increase the validation, of preventive maintenance modes decision generally gotten by analyst's subjective and qualitative judgment in reliability-centered maintenance analysis (RCMA), a projection model of intuitionistic fuzzy multiple attribution decision making for preventive maintenance modes in RCMA was presented. An illustration was used to validate the model of decision making about preventive maintenance modes in RCMA for vehicle equipment. The results indicate that the model is suitable to select the optimum preventive maintenance mode. Compared with the fuzzy comprehensive model that describes fuzzy information only by degree of membership, the intuitionistic fuzzy model more precisely and entirely describes fuzzy information come from RCMA by degree of membership, non-membership and hesitation. Then it is more adequate in group decision making for RCMA. It may be used in developing decision support system for RCMA.
