Problems solved by technology

In the past, the weight value was evaluated by experts, and the weight ratio was directly given by experts' familiarity with pipelines and field research experience, but there was subjectivity to a certain extent, and so far, there was no relevant law Regulations set strict standards for this, so it is somewhat inaccurate

Embodiment Construction

[0036] The present invention will be further described below with reference to the accompanying drawings.

[0037] see figure 2 , the risk factor weight value calculation method of the pipe gallery pipeline of the present invention, comprises the following steps:

[0038] Step S1, identify risk factors, and list each risk factor according to the relationship, such as figure 1 shown:

[0039] The first layer: the overall goal of risk factors;

[0040] The second layer: third-party damage factors, corrosion factors, ontology factors, equipment and operational factors;

[0041] The third layer: line inspection, pipe gallery safety, public relations, third-party operations and natural disasters that belong to third-party damage factors; internal corrosion and external corrosion that belong to corrosion factors; pipeline design and pipeline manufacturing that belong to ontology factors , pipe installation and pipe gallery quality; subordinate to the design, construction, opera...

Abstract

The invention discloses a risk factor weight value calculation method for a pipe of a pipe gallery. The risk factor weight value calculation method includes the following steps that hierarchical listing is conducted on risk factors according to relations; according to a preset two-index comparison evaluation value, pairwise comparison is conducted on risk factors, belonging to the same target of the upper layer, of each layer to obtain comparison evaluation values, and a judgment matrix of the rick factors, belonging to the same target, of each layer is constructed through the comparison evaluation values; a single ranking weight value of the risk factors, belonging to the same target of the upper layer, of each layer is obtained through the judgment matrices and single ranking consistency checking; hierarchical ranking operation and general ranking consistency checking are conducted through the single ranking weight values, total ranking weight values, relative to the general target, of all the risk factor in each layer are sequentially determined from the topmost layer to the bottommost layer. High-reliability and high-objectivity quantitative calculation is conducted on the weights of the risk factors.

Description

technical field [0001] The invention relates to the field of pipe gallery pipelines, in particular to a method for calculating risk factor weights of pipe gallery pipelines. Background technique [0002] Weight is a relative concept. For an indicator, its weight refers to the relative importance of the indicator in the overall evaluation. In the process of risk assessment, the risk factors affecting the pipeline safety of the pipe gallery are divided into: figure 1 several levels shown. [0003] Risk factors at each level have different degrees of importance. How to determine the weight of each factor is a more important issue. In the past, the size of the weight value was evaluated by experts, and the weight ratio was directly given by the expert's familiarity with the pipeline and on-site research experience, but it was subjective to a certain extent, and so far, there is no relevant law. Regulations impose strict standards on this, so it is somewhat inaccurate. SUMM...
