The fuzzy preference programming method was employed to calculate the priority vector from the fuzzy pairwise comparison judgments set

and then ELECTRE Ⅲ based on stochastic dominance and the distance index between the centroid point of a fuzzy number and original point was applied to rank the maintenance strategies in order to select the most appropriate maintenance strategy for a machine.Finally

the proposed method was applied to the maintenance strategy decision making of aeroengine.The result shows that the proposed method is effective.
