| 摘 要： | 基于集对分析理论和三角模糊函数随机模拟理论,探讨了燃气管道的风险评价模型,即应用集对多元联系数表达燃气管道风险评价这一综合不确定问题,以定量描述燃气管道的评价指标样本与评价标准等级之间隶属关系的层次性和模糊性,采用三角模糊数随机模拟技术处理燃气管道风险集对分析中评价标准等级标准的模糊性和刻画集对联系数差异度系数的连续变化过程,进而结合评价指标计算样本与评价标准等级之间的综合联系数,以风险评估燃气管道.实例应用结果及与其他方法对比表明该模型应用于造燃气管道的风险评价是有效可行的,且取得较好效果.

| Abstract: | Based on set pair analysis theory and the theory of triangular fuzzy function of stochastic simulation,the gas pipeline risk assessment model is explored.It is applied to the diverse number of contact assembly to express gas pipeline risk assessment of this comprehensive issue of uncertainty in order to quantitatively describe the evaluation of indicators for gas pipeline samples and evaluation standards for rating the level of the relationship between the subordinate and fuzziness,triangular fuzzy numbers ... |
