Replanning frequencies for a rolling horizon master production schedule under conditions of demand uncertainty and minimum batch-size production

This study extends prior research on rolling schedules and explores the problem of replanning frequency for a rolling horizon master production schedule (MPS) under conditions of minimum batch-size production restrictions and uncertain demand. The MPS model developed in this paper and the determination of the appropriate replanning frequency is based on an actual MPS operation of a paint company. Results indicate that a three-month replanning frequency was the best at this firm because of the cost savings it provided when compared to the other replanning frequencies.
