In the assembly line balance problems (MHDP), the number of stations, the economic limitations, such as the time of circulation, should also take into account the risk of difficulties that may arise due to transactions. Because the repeated work at the assembly stations and the static body positions during these work have a negative impact on the efficiency and effectiveness of the assembly lines of the workers and therefore the disorders of the muscle and skeletal system. In this study, a two-purpose mathematical model has been developed that reflects the time of circulation of the station and the sum of positive deviations from the ergonomic risk score of the stations. In the solution of the multi-purpose model, weight sum, conic scalation, epsilon limitation and melez methods have been applied. Comparing these methods, pareto points obtained in each method have been studied. The real life application of the model developed was carried out in a white item factory. In a single-model simple assembly line consisting of 32 stations, 78 business members, a REBA (Rapid Entire Body Assessment) analysis has determined the ergonomic risk scores for working positions. According to the amount of output required to be obtained daily from the assembly line, the rotation time is determined as 41 seconds. The model and solution methods have been coded in the GAMS (The General Algebraic Modelling System) program and resulted. For the first time in the ergonomic MHDP, different pareto solutions have been obtained in the fields of solutions where the classical solutions methods cannot scan. There has been a reduction in the number of high-risk stations in solutions achieved taking into account ergonomic risks.
