Embodiment Construction

[0050] The present invention will be further described below in conjunction with the accompanying drawings.

[0051] The inventive method is specifically:

[0052] Step 1: Analysis of Factors Affecting Chemical Plant Safety

[0053] The safety production risk management system must not only consider the safety of people themselves, but also consider the impact of production, systems, equipment, and the environment on people. With the advancement of automation, intelligence and systematization, accidents in chemical plants are rarely caused by the system, equipment and environment, and are basically caused by comprehensive reasons, among which the influence of personnel is indispensable, and management is also required. Therefore, this paper builds a chemical plant safety analysis research model around human factors. The main content of the model includes seven aspects: organization, information, work design, man-machine system interface, task environment, workplace design and...

Abstract

The invention relates to a chemical plant safety quantitative evaluation method. The invention establishes a chemical plant safety quantitative analysis research model based on the Bayesian network. Detailed analysis is carried out in the model mainly from the perspective of human factor reliability in aspects of organization, information, work design, man-machine system interfaces, task environments, work place design and operator characteristics, a chemical plant safety index system is established by using a questionnaire and expert judgment method, and meanwhile, a Bayesian network trainingsample is used. And finally, Bayes are used for processing and modeling, the chemical plant safety quantitative value is estimated finally, and the safety level of the chemical plant is judged. The method has the characteristics of accurate reasoning, rapid calculation, comprehensive evaluation and the like.

Description

technical field [0001] The invention belongs to the field of chemical safety, relates to automation application technology, in particular to a quantitative evaluation method for chemical plant safety. Background technique [0002] The chemical industry is an important basic industry in the national economy of various countries and has made outstanding contributions to the economic development of various countries. However, due to the complex process of the chemical industry, the high risk of the material itself, and the existence of high (low) temperature, high pressure, flammable, explosive and corrosive operating environments, it has become a potentially dangerous industry. Accidents often cause serious economic losses, casualties and environmental damage. However, in the past two decades, with the development of society and the advancement of science and technology, the number of major accidents has gradually decreased significantly. However, once a chemical plant cause...
