摘要
介绍了燃气管道失效后果的影响因素,采用模糊数学中的F统计方法确定了"重要"等模糊概念的隶属函数,进而在概率统计的基础上确定了影响燃气管道失效后果的各因素的相对权重,构建了燃气管道失效后果评分指标体系。
In this paper, factors effect the consequence of the failure occurred in flammable gas pipeline were introduced. Based on F statistical method of fuzzy mathematics, the subjection functions of some concepts, such as ＂importance＂, were established. Based on probabilistic and statistical methods, relative weights of the factors are determined. Finally, the index system for the consequence of the failure occurred in flammable gas pipeline was established.
