Embodiment Construction

[0043] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] Such as figure 1 As shown, a chemical plant risk assessment method based on OWA operator weighting, including: according to the analysis of chemical risk factors, obtain the first-level risk factor index and the second-level risk factor index of the process plant evaluation risk factor;

[0045] Evaluate the degree of influence of the first-level risk factor indicators, and correspondingly give the first-level decision-making data set of each first-level risk factor indicator;

[0046] Sort and number each first-level decision-making data set, and calculate each weighted vector in each first-level decision-making data set;

[0047] Weight the first-level decision-making data set through the weighting vector to obtain the absolute weight value of each first-level risk factor indicator; normalize the absolute weight value of each first-...

Abstract

The invention discloses a chemical device risk assessment method based on OWA operator empowerment, and the method comprises: obtaining a first-stage risk factor index and a second-stage risk factor index of a process device evaluation risk factor according to the analysis of a chemical risk factor; evaluating the influence degree of the first-level risk factor indexes, and correspondingly giving a first-level decision data set of each first-level risk factor index; sorting and numbering each primary decision data set, and calculating each weighted vector, absolute weight value and relative weight value in each primary decision data set; evaluating the secondary risk factor index influence degree of the risk factor index subdivision, and correspondingly giving each secondary decision data set of the secondary risk factor index; sorting and numbering each secondary decision data set, and calculating each weighted vector, absolute weight value and relative weight value in each secondary decision data set; and calculating the weight value of the second-level risk factor index by using the relative weight value of each first-level risk factor index and the relative weight value of the corresponding second-level risk factor index.

Description

technical field [0001] The invention relates to the technical field, in particular to a risk assessment method for chemical equipment based on OWA operator weighting. Background technique [0002] Whether it is raw materials or products in petrochemical production, most of them are flammable, volatile, corrosive and toxic, which makes the whole process of petrochemical enterprises have more potential Safety risk factors, these risk factors are always threatening the lives and property safety of people around, if management is not strengthened, accidents will result. Therefore, it is necessary to propose a simple and feasible early warning evaluation method for chemical equipment to analyze and evaluate these potential risk factors, so as to improve the safety of production process equipment and storage facilities. [0003] At present, the most commonly used methods for determining weights are survey statistics, complexity analysis, and Analytic Hierarchy Process (AHP). On t...
