AbstractThis study proposes an alternative approach to the machine requirements planning in a multi-product, multi-machine and multi-stage manufacturing environment. Two techniques were used, a mixed integer programming method where the factors of production such as resource and budget constraints are taken into consideration; and a multi-objective optimization goal programming model, where the conflicting goals of meeting demand and the minimization of the use of scarce resources are taken into account. The solution of the problem specifies the number of production hours necessary in each shift to meet demand, and the number of machines required in each work center. Sensitivity analysis, making changes on the right hand side parameter - demand, coefficient of the working hours for each shift, and priority restructuring of goals, were performed on the mixed integer programming and goal programming models, respectively. The models were subsequently applied to a hard disc manufacturing company and integer and continuous solutions generated from the two models were compared. Computational efficiency was also noted for each approach .
