| 摘 要： | 针对管道风险评分法采用统一权重对管道进行评价，使得评价结果不能够真实反映出管道风险状况这一问题，以管道风险评分法为基础，引入熵权理论对其进行改进。通过计算各事故因素的熵权值，确定出各风险因素在整条管道事故因素中所占的权重，明确各因素对管道的影响程度，使得风险评分方法反映出的管道风险情况更为真实、合理，最后采用改进的管道风险评分法对北一线进行了风险评价。

| Abstract: | Expert safety testing（EST）use the uniform weights to evaluate the pipeline,making the evalua-tion results can not truly reflect the risk profile of pipeline.So base on the EST,introduce the entropy the-ory to improve it.Determine the weight factors of every risk factor by calculating the entropy value of every accident factor,clear out the influence of various factors on the pipeline,make risk scoring methods can be more reasonable,accurately reflect the risk of pipeline case.At last,north line pipeline are evaluated by applying the improving method. |
