基于熵权属性识别理论的管道第三方破坏可能性研究

为全面与贴近实际地保证评估结果的准确性,从管道沿线社会环境、居民、企业、地方政府、管道公司5个方面辨识导致第三方破坏发生的影响因素,根据第三方破坏风险评估管段划分原则对管道分段,对各评估指标按百分制赋予分值。根据所评管段各评估指标提供的信息,应用熵权属性识别理论,计算评估指标的权重和属性测度,基于有序分割类和属性识别准则,利用置信度准则综合评估管道发生第三方破坏的可能性。最后,计算出管道第三方破坏可能性的综合评分值。通过算例表明,沿线地方经济发达程度与建设活动,员工自身素质,居民、企业、地方政府同管道公司关系密切程度,管道遭受人为故意破坏时的响应速度的对第三方破坏发生的影响较大。属性识别结果表明,该区段管道发生第三方破坏的可能性偏高,管道公司应对影响因素予以重视和持续地关注。

Study on Possibility of Pipeline Third-party Damage Based on Entropy Coefficient of Attribute Recognition Theory

In order to comprehensively and realistically ensure the accuracy of evaluation results,risk factors that cause pipeline third-party damage are identified from social environment,residents,enterprise,local government and pipeline company along the pipeline,pipeline is divided according to pipeline sectioning principle suitable for third-party damage,evaluation indicators are graded by hundred mark system.According to the information of evaluation indicators of assessed pipeline segment,entropy coefficient a...
