Abstract
Aim: One of the major global occupational diseases and injuries is musculoskeletal disorders, which leads to increased costs and reduced working productivity. It is essential to assess the risk factors that influence development of these diseases. The purpose of this study was to determine the relationship between risk factors affecting work-related musculoskeletal disorders (WMSDs) in the food industry using the Fuzzy DEMATEL method.

Methods: In this study, 46 occupational risk factors related to musculoskeletal disorders in the food sector were selected from related articles and classified according to the 4m method. Fuzzy DEMATEL study is designed and delivered to experts. Finally, these risk factors were evaluated using the Fuzzy DEMATEL method.

Findings: The cause- effect relationship between 46 risk factors was determined using the Fuzzy DEMATEL method. According to results, the age factor (D-R=2.26) has a greater influence compared to other identified risk factors (is the most causal) and the job satisfaction factor compared to other identified risk factors, is the most influential factor (D-R=-2.26). According to the results, the most important risk factor is the duration of work (D+R=7.46) and the least important is related to the genetic risk factor (D+R=2.64).

Conclusion: The DEMATEL method allows us to better plan and solve problems. In this way, in order to better understand cause-effect relationships, we can divide several criteria into cause-effect groups to build a correlation map.
