Durability Environment Division of Concrete Structures Based on Combination of Fuzzy and Rough Set

Abstract:

Article Preview

In this paper, fuzzy set and rough set theory were used to the research of durability environment division of concrete structures. Based on discretization of the measured data, the significance of attributes among rough sets was estimated instead of weight determination, and a relation data model about the durability effecting factors of concrete structures was established. A knowledge system was built through making attribute value into eigenvalue. During data analysis, the assessment of the regional factors was computed by analyzing the support and significance of evaluation method for the predicted object. The proposed approach overcomes the subjectivity of traditional weight determination method, After researching on durability environment divisions of concrete structures in Shenzhen city, the result shows that the proposed approach overcomes the subjectivity of traditional weight determination method, possesses much more objectivity and improved the accuracy and efficiency of comprehensive evaluation.
