Abstract

Aiming at condition assessment for multiple characteristics, this paper proposes the combination weighting method to make full use of information detected by routine tests. Fuzzy analytical hierarchy process (FAHP) is a modified subject weighting method and anti-entropy method is a modified objective weighting method. Combination weighting method combines FAHP and anti-entropy method to get the more reasonable results. First, the index system of DC XLPE cables are established. Second, weight parameters of each index are calculated by FAHP and anti-entropy method. Third, associating weight parameters calculated above, weight parameters of combination weighting method are deduced. Then, calculate the relative degree of deterioration and degree of membership of each index. Finally, use weight vector calculated by combination weighting method and degree of membership matrix to get the condition membership. Compared to FAHP and anti-entropy method, combination weighting method has more smooth distribution of membership and can reflect the potential faults according to some sensitive indexes.
