Abstract—At present, more and more attentions have been paid to dam risk management around the world. In order to deal with the fuzziness and randomness of dam failure, the cloud model was introduced into the risk assessment of dam failure, which was combined with Analytic Hierarchy Process(AHP) method and fuzzy theory, and then the multilevel fuzzy comprehensive assessment of dam failure risk was realized based on the cloud model. The improved AHP based on the judgment scaled with cloud model was proposed, and the cloud model was also used to determine the membership function in fuzzy assessment of dam failure risk, finally the group decision can be made with the improved algorithm that integrated methods of AHP and fuzzy with cloud model. Based on the improved algorithm, a system for fuzzy comprehensive assessment of dam failure risk based on cloud model was designed and developed. The application shows that the proposed algorithm can reflect both the fuzziness and randomness in dam failure, and therefore has much more stronger robustness than the traditional AHP and fuzzy assessment methods.
