| Abstract: | 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. |
