基于直觉模糊层次法和云模型的水工钢闸门评估.

When evaluating the safety status of hydraulic steel gate in service, it is usually necessary to comprehensively consider the influence of evaluation indexes from many aspects, among which there are qualitative and quantitative indexes, which is an issue of uncertainty and fuzziness. Based on this, this paper combined the intuitionistic fuzzy hierarchy method and cloud model method to evaluate the safety state of the gate. Firstly, this paper built the evaluation structure system of hydraulic steel gate based on the idea of hierarchy method, and then invited experts to evaluate and compare the indicators on the basis of intuitionistic fuzzy theory, established the judgment matrix and comprehensively analyzed the weight of each indicator. To adopt the method of cloud model, combining with engineering example, set up the index of diagnosis of cloud, the diagnosis of synthesis of various cloud chart, finally got the diagnosis cloud gate test result and comparing with state chart, finally it was concluded that the gate security status. Comparing with the actual situation, the results of this method are accurate and intuitive. [ABSTRACT FROM AUTHOR]
