TI  - EVALUATION OF PHYSICAL AND MENTAL FATIGUE IN AN ASSEMBLY LINE
AB  - Employees in production industries are exposed to different physical and mental loads due to  individual differences or job requirements. Because of the fatigue caused by these loads varies, there  is a need to evaluate the resting shares given to employees at various workstations accordingly.  Giving the employees the same resting allowance for the types of work that vary depending on the  workstations does not ensure the ergonomic adaptation of the work to the person. In this study, the  impact of the activities carried out in the automotive production industry's seat assembly line on the  rest allowances given to the employees has been handled with an integrated system and the fatigue  values due to the changes in the job type are reflected in the rest shares. In the evaluation of the  physical fatigue of the employees, working posture was examined by REBA (Rapid Entire Body  Assessment) and movements were analysed by MURI. Mental demand, physical demand, effort,  performance, temporal demand and frustration were studied with NASA-TLX (NASA Task Load  Index) to assess mental fatigue. The data obtained from these 3 methods were combined with the  multi-criteria decision making method AHP (Analytic Hierarchy Process), and weights related to  physical and mental fatigue were formed. The general fatigue score developed based on these  weights was used in the calculation of variable rest allowances. Thus, the effect of fatigue values  obtained as a result of ergonomic analysis methods on rest shares for different workstations was  calculated instead of the standard rest allowances given to employees equally for each station and it  was ensured that employees are given rest breaks that vary according to different loads at the  workstation.
