International audience; In Manufacturing Planning and Control Systems, the Master Production Schedule (MPS) makes a link between tactical and operational levels, taking into account information provided by end items, demand forecast as well as Sales and Operations Planning (S&OP) suggestions. Therefore, MPS plays an important role to maintain an adequate customers service level and an efficient production system. In a rolling planning horizon, MPS is periodically computed over whole operational horizon. The differences between scheduled quantities obtained by this process are related to MPS instability. This feature of MPS has negative effects, both, at tactical level and also at operational one. In this paper, a Mixed Integer Programming model is proposed for MPS instability. The proposed model considers instability minimization in addition to inventory costs and set up. Simulation is used to take into account stochastic demand. Computation experiments are presented in order to show the efficiency of this approach by finding stable MPS without a considerably increase in the total cost.
