摘要
提出了根据模糊综合评判、定义结构参数用以表示焊接缺陷损伤程度的方法。建立了基于模糊集理论处理含焊接缺陷化工设备和管道承受疲劳载荷安全评定中解决不确定和非精确性的方法,并编制了相应的专家系统。
A fuzzy multicriteria modelling method of defining a structural parameter for representing the grade of welding defect damage is presented. The methodology for safety assessment of process equipment and piping containing welding defects in fatigue loading based on the theory of fuzzy set for treatment of imprecisions and uncertainties is proposed, and the related expert system has been built.
