摘　　要：为了解决在流体管网的计算和分析中遇到的问题,借助模糊数学理论,引入模糊相对阻抗的概念,探讨了模糊最不利环路的算法及其决策方法。为解决含有不确定性输入参数的管网最不利环路分析提供了一条简捷而有效的途径。最后通过实例分析,给出了模糊最不利环路的隶属函数和总压降的决策方法。In order to solve the problems in calculation and analysis of fluid pipeline networks, the concept of fuzzy relativity resistance is introduced by using fuzzy theory. And the algorithm and the decision-making technique for the index circuits are discussed. And a concise and effect path was given to analyze the problem of index circuits with uncertainty parameter. Finally, a practical example is given to represent and analyze the membership function of the index circuit and determination of its overall pressure drop.
