Fuzzy mathematics-based gas pipeline third-party damage risk assessment method

Abstract

The invention discloses a fuzzy mathematics-based gas pipeline third-party damage risk assessment method, which can realize quantitative assessment of gas pipeline third-party damage risk. According to the technical scheme, various possible conditions of a gas pipeline third-party damage accident are systematically analyzed by adopting an analytical hierarchy process and an MMESE system theory for characteristics of diversity, complexity, uncertainty and the like of the gas pipeline third-party damage accident, a three-level hierarchical structure model is built, and a triangular fuzzy number is introduced according to a fuzziness characteristic, so that a relative importance degree among factors is quantitatively represented, the limitation of the analytical hierarchy process is overcome, human subjective influence in a conventional assessment method is reduced, and weight allocation is more accurate, objective and reasonable. The method has the advantages that the limitation of the analytical hierarchy process is overcome, and the subjective influence of the human factors in the conventional assessment method is reduced; and the weight allocation is reasonable, and an assessment result is objective and accurate.

Description

technical field [0001] The invention relates to a gas pipeline risk assessment method, in particular to a fuzzy mathematics-based third-party damage risk assessment method for the gas pipeline. Background technique [0002] With the rapid development of urban construction and gas pipeline network, gas pipelines inevitably pass through densely populated and economically developed municipal centers. However, the gas pipeline transports flammable and explosive gas under pressure. Once the pipeline is perforated and cracked, the flammable and explosive gas will be ejected quickly, causing serious safety accidents. At present, third-party destruction of gas pipelines has become the main cause of gas leakage. If we can comprehensively consider various factors that lead to third-party damage based on the use of urban pipelines, conduct hierarchical assessments from the root causes, predict pipeline risk levels, and take targeted management measures, it will help reduce third-party...
