    Improvement of Bayesian Water Supply Network Evaluation Model Based on Triangular Fuzzy Number and Its Application by SHI Xiaolin, DING Xiangyi, LIU Siran, LING Minhua

    Published 2020-01-01
    “…In view of the shortcomings of the single weight determination method and the uncertainty of the pipeline health level determination method in the Bayesian water supply network evaluation model based on triangular fuzzy number, this paper improves it by the coefficient of variation method and the fuzzy analytic hierarchy process (FAHP) to calculate the comprehensive weight, thus determine the pipeline health level based on the overall score, and applies the improved model to the health status assessment of the water supply network in Yunhe County, Zhejiang Province.The results show that: for health grades, 53% of the pipelinesare in class I, 44% of the pipelines are in class II,and 3% are in class III. …”
