Method for analyzing human factor reliability in process of manufacturing pressure-bearing equipment

Abstract

The invention discloses a method for analyzing human factor reliability in process of manufacturing pressure-bearing equipment. The method includes: (1) making a manufacturing flow diagram; (2) recording qualifications, working experiences and training situations of workers in a corresponding link; (3) establishing a fault tree of the link; (4) analyzing human factor errors in steps according to the errors in the manufacturing process so as to analyze reasons of the errors; (5) dividing a researched bottom event into organization and management errors and cognitive style errors according to results of the step (4); (6) evaluating the cognitive style event to obtain a weight; obtaining a weight of the organization and management event; obtaining a final weighting probability value according to results of the step 5, and determining a treetop probability value on the basis of the final weighting probability value; (7) determining the minimum cutest of the fault tree, determining an importance degree of the human-factor error bottom event according to the minimum cutest; (8) confirming the size of manufacturing risk under the condition managed by the workers and organizations, and putting forward advises.

Description

Technical field [0001] The invention relates to the field of pressure-bearing equipment risk analysis and human factor reliability, and is a method for evaluating and controlling the manufacturing process of pressure vessels. Background technique [0002] Pressure-bearing equipment is equipment that uses fluid pressure as the basic load, such as pressure vessels, pressure pipes, pressure boilers, and pressure-bearing accessories. With the progress of science and technology and the development of industrial production, the use of pressure equipment has become more and more extensive. At present, pressure equipment has become the chemical industry, petroleum industry, petrochemical industry, coal, metallurgy, nuclear energy, aerospace, marine engineering, light industry , Textile, food, urban construction and other important equipment in various sectors. It not only affects the development of the national economy, but also has potential dangers. Once an accident occurs, it often c...

AI Technical Summary

Problems solved by technology

The human-factor reliability of the pressure-prone manufacturing industry, which also has major dangers, cannot directly adopt and apply the methods in mature industries due to its own characteristics, resulting in research work that has not yet started.
