Pipeline integrity evaluation method and device and electronic equipment

Abstract

The invention provides a pipeline integrity evaluation method and device and electronic equipment. The method comprises the steps that an analytic hierarchy process is adopted, and the initial weight of each evaluation index in an evaluation index system is determined; based on the data set of each evaluation index of each pipeline, a gray correlation analysis method is adopted to determine a coupling relationship among the evaluation indexes, and the initial weight is corrected according to the coupling relationship among the evaluation indexes to obtain a comprehensive weight of each evaluation index; and evaluating the integrity of the pipeline based on the comprehensive weight. According to the embodiment of the invention, the initial weight of each evaluation index in the evaluation index system is determined and the initial weight is corrected according to the coupling relationship among the evaluation indexes to obtain the comprehensive weight of the integrity evaluation index, so that the subjective randomness caused by purely using a subjective weighting method is avoided; and data information distortion possibly caused by purely using an objective weighting method is avoided, and accurate judgment and evaluation of the integrity state of the pipeline are realized.

Description

technical field [0001] The invention relates to the technical field of pipeline management, in particular to a pipeline integrity evaluation method, device and electronic equipment. Background technique [0002] Pipeline integrity evaluation is to determine the applicability of the pipeline based on the integrity state of the pipeline by evaluating the integrity state of the pipeline, thereby providing a decision-making basis for the operation and maintenance of the pipeline. At present, the evaluation of pipeline integrity generally focuses on the evaluation of the remaining strength or remaining life of the pipeline, mainly based on the defect size information obtained from pipeline inspection, focusing on the result-based evaluation, without considering various factors that affect pipeline integrity and their Affecting the process, it is difficult to analyze the key factors leading to pipeline failure from the source, and it is impossible to give targeted improvement meas...

At present, the evaluation of pipeline integrity generally focuses on the evaluation of the remaining strength or remaining life of the pipeline, mainly based on the defect size information obtained from pipeline inspection, focusing on the result-based evaluation, without considering various factors that affect pipeline integrity and their Affecting the process, it is difficult to analyze the key factors leading to pipeline failure from the source, and it is impossible to give targeted improvement measures

Even if multiple factors are considered in the existing evaluation methods, since a certain influencing factor may cause another or multiple influencing factors to change, this change may be positive or negative. If the evaluation is based on independent factors, will inevitably affect the accuracy of the evaluation results
