依托层次分析法构建了油气管道判废综合评估的层次分析法层次结构模型，详细给出了判断矩阵层次排序和一致性检验的数学模型、具体方法和详细步骤，并最终给出判断结果。层次分析法在油气管道判废综合评估上的应用，综合了定性与定量分析、主观与客观判断，可为油气管道运营企业决策老龄油气管道的废弃工作提供有效指导。

Based on analytic hierarchy process (AHP),an AHP hierarchy model for comprehensive evaluation of judging oil and gas pipelines to be abandoned or not is set up.The mathematical model,specific methods and detailed steps of judging matrix level sort and consistency check are given in details,and final judge results are given.Application of AHP in abandonment evaluation of oil and gas pipeline combines qualitative with quantitative analysis,and subjective with objective judgment,and can provide effective guidance for oil and gas pipelines to decide abandonment of aging oil and gas pipelines.
