Research on construction of work safety early-warning index model for enterprises
To solve the difficult problem in the construction of risk early-warning index during the work safety process of en-terprises,a double-weight work safety early-warning index model based on multi-index coupling was put forward. Firstly,the risk factors causing work safety accidents were analyzed,then the questionnaire concerning the work safety early-warning in-dex (SPI) was designed,and through the network data platform,the enterprise employees were organized to take part in the questionnaire survey. Secondly,the effective questionnaires were selected through data analysis,and the optimal SPI system was determined by the Pearson correlation coefficient method and Delphi method. Finally,the improved analytic hierarchy process (AHP) method was employed to adjust the contribution degree of the questionnaire scores of different age groups,and the CRITIC method was utilized to determine the "double-weight method" weighting of index weights. The SPI model was es-tablished,and taking a certain enterprise as an example,the application research was carried out. The results show that the SPI model is precise and reliable,and has been recognized and promoted by enterprises. The research results can provide ref-erence for the work safety early-warning management of enterprises.
