Chemical enterprise environment risk evaluation method and system

Abstract

The invention provides a chemical enterprise environment risk evaluation method and system. An ANP network analysis and evaluation structure of chemical enterprise environment risks is constructed according to the chemical enterprise environment risks; determining a risk grading standard of the chemical enterprise environment according to the ANP network analysis and evaluation structure; calculating an overall incidence matrix of the environmental risks of the chemical enterprises by applying a matter-element analysis method according to a risk grading standard; and determining the grade of the chemical enterprise environment risk according to the overall incidence matrix of the chemical enterprise environment risk. Starting from systematic characteristics of environmental risks, a chemical enterprise environmental risk evaluation index framework is provided, and risk factors possibly involved by chemical enterprises are comprehensively covered from three aspects of risk sources, risk control and risk receptors. A network analysis method and a matter element analysis method are combined, and a general quantitative evaluation method for comprehensive evaluation of the chemical enterprise environment risk is determined, so that comprehensive evaluation of the comprehensive risk of the chemical enterprise environment is realized.

Description

technical field [0001] The invention relates to the field of environmental risk assessment of chemical enterprises, in particular to a method and system for environmental risk assessment of chemical enterprises. Background technique [0002] Chemical companies are listed as high-risk industries due to their complex process configuration, high temperature and high pressure process conditions, and harmful substances contained in raw materials. Accurate identification and comprehensive evaluation of environmental risks in chemical enterprises can effectively reduce the probability of chemical enterprise risk accidents and reduce the impact of accident hazards. [0003] At present, the identification of risk sources for chemical companies is still in its infancy. Due to the lack of systematic analysis based on environmental risks themselves, only a single event or a single dangerous link is focused on, resulting in unreasonable overall evaluation indicators of the risk evaluatio...

Problems solved by technology

[0003] At present, the identification of risk sources for chemical companies is still in its infancy. Due to the lack of systematic analysis based on environmental risks themselves, only a single event or a single dangerous link is focused on, resulting in unreasonable overall evaluation indicators of the risk evaluation system, which is difficult to implement in practice. The operation or evaluation results are poorly differentiated; only the subjective evaluation method is used to determine the evaluation value and environmental risk level of the evaluation object, resulting in strong subjectivity of the final evaluation results

Therefore, the existing environmental risk assessment methods are difficult to fully reveal the comprehensive environmental risks of chemical enterprises.
