Description
Summary:A stability and controllability analysis of a production control scheme based on the demand forecast, on finished product inventory level and work in progress feedback signal is presented. The controllability analysis helps to identify the causes of the production control inefficiency in recovering inventory offsets when an unpredictable event changes the work in progress or the completion rate values. A modification to the original scheme is also proposed. The modified scheme ensures the recover of inventory offset in all working conditions and it also presents reduced production fluctuations compared to the original scheme. Moreover the modified scheme is easy to implement in an operating plant.
