基于模糊评价法确定聚乙烯燃气管道的检验周期

Determination of Inspection Period of Polyethylene Gas Pipeline in Use Based on Fuzzy Evaluation Method

在聚乙烯燃气管道全面检验的实践过程中,部分管道使用单位对检验周期存在诸多质疑,甚至不认可。采用层次分析-专家打分的模糊综合评价法进行聚乙烯燃气管道安全状况等级评定比较客观公正,可操作性强。工程实际应用后,使用单位对管道安全状况的结论和检验周期的确定更容易接受。

In the practice of comprehensive inspection of PE gas pipeline,there are many doubts about the determination of inspection cycle.In this paper,the fuzzy comprehensive evaluation method based on analytic hierarchy process and expert scoring is objective,fair and operable.After the practical application of the project,the conclusion of the user on the safety status of the pipeline and the determination of the inspection cycle are more acceptable.
