油气管道第三方破坏风险管理效能评估方法研究

Study on Risk Management Effectiveness Evaluation of the Third Party Damage for Oil and Gas Pipeline

在油气管道第三方破坏风险管理效能评估中,存在十分复杂的影响因素和关联性。针对第三方破坏风险管理的特点,依据事故过程关联因素建立效能评估指标体系,运用多属性决策效能评估加权的TOPSIS方法,对从5个不同管道公司获取的指标调查结果进行整体性效能综合评估。其中,利用改进的灰靶理论的贡献度算法确定加权TOPSIS方法中的各指标权重。应用案例分析表明,这种方法的评估结果具有一定的准确性和合理性。

In the third-party damage risk management effectiveness evaluation of oil and gas pipeline, there are complex influence factors and the correlation among them. An index system for the third-party damage risk management effectiveness evaluation of oil and gas pipeline is established according to the characteristics of the third-party damage risk management and the correlation among the influencing factors of the accident, and the investigation results of the third-party damage risk management effectiveness evalua- tion indexes obtained from five pipeline companies are comprehensively assessed by using TOPSIS weighting method for the multi-attribute decision-making effectiveness evaluation. The weights of the indexes in TOPSIS weighting method are determined using the improyed technical indicators contribution algorithm based on gray target theory. The analysis of a case shows that the evaluation results for the third-party damage risk management effectiveness of oil and gas pipeline obtained using the method in this paper have a certain accuracy and reasonableness.
