In this article, we consider the mixed model assembly line sequencing problem with work overload minimization (MMSP-W). We consider an assembly line having operators with different characteristics. We propose a formulation based on a linear programming approach. The model is implemented using the CPLEX solver. Numerical tests are carried out on generated data and on an industrial case study from a truck assembly line. Computational results demonstrate the considerable improvements obtained in comparison to the traditional car sequencing approach.
