specific Embodiment approach 1

[0020] A safety behavior analysis method based on structural equations in this embodiment analyzes the influencing factors of personnel safety behavior through the structural equation model, and determines the safety management work objectives, and quantifies the safety behavior status by calculating the interaction between various influencing factors Analysis and quantitative management, using the logical relationship between the influencing factors to analyze the advantages and disadvantages of the automated production method, evaluating the optimized man-machine system, conducting Jack simulation analysis, and confirming the results.

specific Embodiment approach 2

[0021] The difference from the first embodiment is that a structural equation-based safety behavior analysis method in this embodiment includes the following steps:

[0022] The first step is to analyze the influencing factors of safe behavior in the production and processing process of the tobacco industry, and determine that individual incorrect attitude, lack of skills, and poor physical condition are the predictors of unsafe behavior;

[0023] The second step is to put forward the evaluation set of safety behavior influencing factors scale; collect enterprise data in the form of questionnaire; select enterprises with traditional production process and automatic production process respectively, and compare the analysis results of the two models with mathematical analysis means;

[0024] Likert's 5-level scale was adopted, and the questionnaire was used after prediction and verification of reliability and validity index values;

[0025] The third step is to quantitatively an...

specific Embodiment approach 3

[0029] The difference from the second embodiment is that in this embodiment, a structural equation-based safety behavior analysis method, step 1 analyzes the factors affecting safety behavior in the production and processing of the tobacco industry, and determines the individual's incorrect attitude and lack of skills. , and the process by which poor physical condition is a predictor of unsafe behavior is,

[0030] It is determined that the individual's incorrect attitude, lack of skills, and poor physical condition are the predictors of unsafe behavior, and the measurement questionnaire is designed through field investigation and consultation, and the reliability and validity of the questionnaire are analyzed.

Abstract

The invention discloses a safety behavior analysis method based on a structural equation, and belongs to the field of optimization and evaluation systems. An existing optimization evaluation system isnot perfect enough. The invention discloses a safety behavior analysis method based on a structural equation, personnel safety behavior influence factors are analyzed through a structural equation model. The method comprises the following steps: acquiring influence factors, determining a safety management work target, calculating interaction among the influence factors, carrying out quantitativeanalysis and quantitative management on safety behavior conditions, analyzing advantages and defects brought by an automatic production mode by utilizing a logic relation among the influence factors,carrying out optimized man-machine system evaluation, carrying out Jack simulation analysis, and confirming a result. According to the invention, the WSR law theory is applied to the optimization of the man-machine system; optimization suggestions are provided for management work from the three levels of an organization layer, a physical layer and a human organization layer, the designed content is analyzed through JACK simulation software, manpower and material resources are saved, a factory can be online as soon as possible, the manual process is optimized, the safety of workers is enhanced,the shutdown time is shortened, and the retraining cost is reduced.

Description

technical field [0001] The invention relates to a safety behavior analysis method based on structural equations. Background technique [0002] The unsafe behavior of people and the unsafe state of things are the direct causes of accidents, and the unsafe state of things needs to be identified and managed by people, so the unsafe behavior of people is an important cause of accidents. Unsafe behavior refers to direct mistakes that can cause accidents, and the formation of human unsafe behavior is caused by many reasons and is extremely complicated. Whether analyzing unsafe behaviors from the three dimensions of individual, environment, and management, or constructing a hierarchical structure model of factors affecting employee unsafe behaviors from the four dimensions of organization, individual, leadership, and environment, or analyzing unsafe behaviors from managers, team leaders, and front-line employees The three subjects construct the influencing factor system of employe...
