A method for assigning values ​​to evaluation indicators of safety management level

Abstract

The invention discloses a safety management level evaluation index assignment method, which belongs to the technical field of safety evaluation of oil refining and chemical enterprises. The assignment method includes: obtaining all accident cases, obtaining the number n of major accidents related to all refining and chemical enterprises; analyzing all accidents through the fault tree and obtaining the root cause event R of each accident ij , where i is the i-th major accident, j is the j-th root cause of the i-th accident; calculate the accident hazard degree w i That is, the quantified value of the accident hazard degree of the i-th major accident; calculate the root cause hazard degree f 1 (i, j) is the structural damage degree of the root cause of the jth type in the ith major accident. The safety management level evaluation index assignment method of the present invention increases the scientificity of the evaluation index weight quantification, and can also solve the problem of unstable demand through an iterative process, and can better scientifically evaluate the safety management of refining and chemical enterprises.

Description

technical field [0001] The invention relates to the technical field of safety evaluation of oil refining and chemical enterprises, in particular to a method for assigning values ​​of safety management level evaluation indicators. Background technique [0002] Refining and chemical enterprises are an important pillar of the national economy, and process safety accidents often have serious consequences. For major process safety accidents, the government and the public pay the most attention. Find out the cause of the major process accident safety accident, and also find the way to prevent the major accident. [0003] Through the analysis and statistics of the root causes of chemical accidents in recent years, it can reflect the inadequacy of the safety management level of enterprises to a certain extent, and can effectively guide the safety production of enterprises in our country. The existing safety inspection and evaluation index system has certain authority, but whether ...
