Comprehensive Evaluation on Occupational Hazards for Steel Rolling Workshops with the Interactive Effects of Multiple Hazards

In view of the interactive effects of multiple hazards in steel rolling workshops, a comprehensive evaluation model of occupational hazards is set up, which is based on Analytic Hierarchy Process (AHP) and two-tuple linguistic information. Firstly, in order to characterize interactive effects, correction factors of the interactive effects are introduced, and the scoring method is provided. Secondly, construction steps of the model are presented, including the establishment of the index system of comprehensive evaluation on occupational hazards for steel rolling workshops; the determination of indexes by AHP; the fixing of the assessment set of two-tuple linguistic information; processing method for raw data standardization of heat, noise and dust. Finally, an application example is presented and it shows that the evaluation method not only considers the interactive effect of multiple hazards, but also is simple to be operated and easy to be implemented.
