A biobjective model for production planning in a cement factory

This paper is an illustration of the application of biobjective linear programming to determining the optimal allocation of production materials to the major production facilities. The system under consideration is a cement factory. However, the approach and methodology are sufficiently general that the method can be applied to similar problems in other firms.Two objectives of the factory are distinguished: minimization of manufacturing cost and maximization of capacity utilization. Addressed to the needs of the biobjective case, a technique, which is referred to as ‘compromise constraint’ technique, is introduced.
