Design of the evaluation model for total ergonomics interventions with fuzzy approach
Journal Title: Scientific Journal of Pure and Applied Sciences - Year 2012, Vol 1, Issue 3
Abstract
The present study describes the development of a theory for the guidance of ergonomic interventions (EI) and evaluation processes with the help of fuzzy approach. The study was carried out at an educational center (EC) with the micro- and macro-ergonomic interventions. The combined results of both interventions have demonstrated the positive effects of these techniques in increasing the productivity and reducing the musculoskeletal disorders (MSDs). So, the overall annual performance of the educational center had a significant rise in terms of lower costs, increased revenue and work expansion with less human force. Analysis of questionnaire data "body mapping" with the fuzzy approach has shown that the surrounding surface and fuzzy numbers’ intervals, belonging to the degree of comfort of the qualitative dimensions, were more in the control population as compared to the treatment ones, which indicates that the index of ergonomic interventions is positive in EC.
