油气长输管道的本质安全程度一直是政府部门和企业安全管理者重点关注的问题。本文对油气长输管道本质安全评价指标和评价模型进行研究,对肯特管道评价法的指标进行了改进,建立了基于模糊推理评价法的本质安全评价模型,采用MATLAB模糊逻辑工具箱通过Mamdani模糊推理算法计算出管道的本质安全水平。通过实例验证,评价结果精确,具有应用价值。 The inherent safety of long-distance oil and gas pipelines has always been a major concern of government agencies and corporate safety managers. This paper studies the evaluation index and evaluation model of intrinsic safety of long-distance pipeline, improves the index of Kent pipeline evaluation method, establishes the intrinsic safety evaluation model based on fuzzy inference evaluation method, and uses Mamdani fuzzy reasoning with MATLAB fuzzy logic toolbox The algorithm calculates the intrinsic safety of the pipeline. Through the example verification, the evaluation result is accurate and has application value.
