摘要
利用检测服役期间海底管线缺陷检测的有关数据,探讨用模糊理论来评定缺陷等级的划分方法,以便对管线进行检测与维护。建立了模糊综合评判的数学模型,并讨论了隶属函数和权重的构建方法。应用模糊综合评判来确定管线缺陷级别,实例表明是可行的。
A grade-judging method of defect for offshore pipeline is studied by means of fuzzy theory,based on the defect data.In addition,the model of comprehensive fuzzy assessment is introduced and the designing method of the membership function and the weighting function is discussed.And many examples prove that the method of comprehensive fuzzy assessment is very effectual.
