Embodiment Construction

[0031] The present invention will be further described below.

[0032] The inventive method is specifically:

[0033] Step 1: Identify the indicator factors that affect the target.

[0034] The safety of chemical plants should not only consider the safety of personnel themselves, but also consider the impact of production, systems, equipment, and the environment on people. Seven influencing factors (including organization, information, job design, human-machine system interface, task environment, workplace design, and operator characteristics) and 30 subfactors were identified.

[0035] Step 2: Establish a hierarchical structure system based on indicators.

[0036] According to the 7 factors and 30 sub-factors determined by human factors affecting the safety of chemical plants, a hierarchical structure is established. See the hierarchical structure diagram figure 1 .

[0037] Step 3: Determine the comment set and standard cloud model of the indicator.

[0038] Step 3.1 Es...

Abstract

The invention relates to a chemical production safety assessment method based on an improved fuzzy analytic hierarchy process. The chemical production safety assessment method based on an improved fuzzy analytic hierarchy process is provided for solving some problems in chemical plant safety assessment. The chemical production safety assessment method comprehensively considers main safety factorsinfluenced by human errors in seven aspects of organization, information, work design, a man-machine system interface, a task environment, work place design and operator characteristics, and establishes a hierarchical structure system by adopting an analytic hierarchy process, quantifying indexes by adopting a triangular fuzzy function, calculating index weights by adopting a logarithm fuzzy priority planning method, and finally obtaining the safety level of chemical plant production by applying a cloud model. Meanwhile, simulation checking calculation is carried out on the chemical productionsafety assessment method, and a simulation result shows that the improved fuzzy analytic hierarchy process serving as a chemical production safety evaluation method has reliability, practicability and scientificity.

Description

technical field [0001] The invention belongs to the field of chemical safety, relates to the application of analytic hierarchy process, in particular to a chemical production safety evaluation method based on improved fuzzy analytic hierarchy process. Background technique [0002] At present, the production technology of the chemical industry has been updated day by day, and many major accidents are mainly caused by human errors. Statistics show that in the process of chemical production and storage, industrial accidents are at least partially caused by human beings in the range of more than 60%, which is a terrifying proportion. Therefore, it is clear that the relative number of accidents due to human error is increasing, while the relative number of accidents due to technical failure is decreasing. At present, there are few studies on the direction of human error in the production safety evaluation methods of chemical enterprises. Contents of the invention [0003] Aim...
