ABSTRACT Due to the facts that there are more risks and difficulties in long-distance water diversion engineering operation, a comprehensive evaluation model of sub-constraint based on constant weight is established based on sub-constraint theory. In order to eliminate the individual differences in the experts’ weights, analysis on the differences in experts’ weights is implemented based on the correlation theory and induced ordered weighted averaging. In this way, the indicator weights are determined, and the safety risk comprehensive evaluation of long-distance water diversion project operation is realized. Meanwhile, the methods of reducing the indicator’s contribution are used for diagnosing key risk sources. Finally, the Henan section of the Middle Route Project of South-to-North Water Diversion is taken as an example to verify the validity and applicability of the model.
