摘要
Abstract
Abtsr act: In order to reasonably and effectively evaluate the risk of basin flood control engineering system , a comprehensive risk evaluation model based on cloud model theory is established by considering the fuzziness and randomness in the process of risk evaluation.The presented model can describe the fuzziness of evaluation grades by the membership function in cloud model theory, but also consider the randomness of the membership degree with hyper entropy concept in the theory of cloud model. And in order to make the evaluation results more reliable ,it properly determines the comprehensive assessment grade by the varying combined parameters in variable fuzzy set theory. Finally, the new model is applied to risk evaluation of a watershed flood control engineering system , and the results are compared with matter-element model , variable fuzzy sets model and set pair analysis -variable fuzzy set model.The results illustrate that the cloud model is effective and feasible and can indicate the fuzziness and randomness in the process of evaluation ,thus give out a new thinking for basin flood risk analysis .关键词
