Abstract

The invention relates to a fault mode influence and hazard analysis method, computer equipment and a storage medium. The fault mode influence and hazard analysis method comprises the steps of obtaining a first decision matrix of each risk factor of each fault mode; and obtaining a risk weight vector of each risk factor; according to an intuitionistic binary language utility weighting integration operator and the risk weight vector of each risk factor, integrating intuitionistic binary languages of n risk factors of each fault mode in the first decision matrix into a comprehensive binary language of each fault mode; and according to the comprehensive binary language of each fault mode, obtaining a risk level sequence of each fault mode. The evaluation accuracy can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of reliability evaluation, in particular to a failure mode impact and hazard analysis method, computer equipment and storage media. Background technique [0002] The failure mode effects and criticality analysis (FMECA) method is to analyze all possible failure modes of the product and their possible impacts, and classify them according to the severity of the impact of each failure mode and its occurrence probability A method of inductive analysis. [0003] Traditional FMECA ranks the failure modes of products according to the Risk Priority Number (RPN). The risk priority number is obtained by multiplying the evaluation values ​​of the risk factors. Therefore, the traditional FMECA process is relatively simple, resulting in large deviations in the evaluation results. Contents of the invention [0004] Based on this, it is necessary to provide a failure mode impact and hazard analysis method, a...
