| 摘 要： | 本文主要介绍了由故障树分析和非线性模糊综合评价相结合的油气长输管道失效的研究方法。故障树分析方法能找出影响油气长输管道失效的共性因素,但是较难分析实际运行管道中所存在的个性因素和模糊因素。本文在故障树方法所提供的评价因素集和权重集的基础上,利用非线性模糊综合评价方法对油气长输管道失效进行了更为客观的评价。以某输油管道为例列举了该方法的主要步骤,计算结果表明FTA和非线性模糊综合评价的集成方法更加合理、易于工程应用,评估结果更符合客观实际。

| Abstract: | The combination method of fault tree analysis and nonlinear fuzzy comprehensive assessment method was proposed to make research of oil gas pipeline failure.The common factors influencing oil gas pipeline failure could be determined with fault tree analysis.However,the practical operated oil gas pipeline often have some individual factors and fuzzy ones.Nonlinear fuzzy comprehensive assessment method could evaluate objectively based on evaluated factors sets and weight sets provided by fault tree analysis.The new model steps were listed by taking the example of oil gas pipeline failure.The result indicates that the method is more reasonable and easier for engineering application,and the evaluation result is more with the objective reality. |
