The topological importance or functional importance is only taken into consideration, when the existing measures are constructed. Based on functional properties of components, generalized importance measures, which improve topological measures in network theory, are proposed to combine with Choquet integral. In order to overcome the uncertainty and randomness, which exist if a single importance measure identifies critical components, aggregation operator (AO) is given through fusion multi-generalized importance measures and then used to identify critical components of complex electromechanical system. Finally, a case study which selects fuzzy integral to treat as AO is presented to identify critical components of bogie system. The results show that the method with Choquet integral regarding as AO and k fuzzy measure calculating weights, is effective. [ABSTRACT FROM AUTHOR]
