Abstract :Work-related musculoskeletal disorders (MSDs) are among the most common occupational diseases encountered in today\\\'s working conditions. In order to prevent MSD, the strains occurring in employees must be identified. Ergonomic risk assessment methods have been developed in this context examine the physical and environmental factors affecting the employee and ensure that any discomfort that may occur is minimized with corrective suggestions. Therefore, it can be said that ergonomic risk assessment methods can play a major role in preventing MSDs. In traditional ergonomic risk assessment methods, angular deviations of the limbs from the normal posture are taken into consideration. Such methods are not sensitive enough to measure the effect of input variables on the result value, as they give the same risk score for different input variables. This study aims to develop Fuzzy-REBA (F-REBA) to a new scoring system for traditional REBA by using fuzzy sets approach to eliminate the disadvantages of traditional REBA. When the obtained results are taken into consideration, it has been determined that the fuzzy REBA method gives more sensitive results to possible changes in input variables such as the changes of flexion or extension degrees.
