Optimal Work-In-Process control for a closed multistage production system with machine preference

Abstract : In this work, we expose a closed loop production system which have great similarity with the Kanban system as the Work In-Process (WIP) is constant (CONWIP). This system is a multistage single-product and it support more than one machine in every stage. These machines can have different characteristics and they have limited capacity of buffering. We consider also that there is a preference for a machine usage in each stage. We use a Closed Queueing Network (CQN) with a repetitive blocking mechanism to model this system. The used resolution approach is the Maximum Entropy Method (MEM). In a first place, we look for the optimal WIP to keep in this system with respecting a production rate. In a second place, the routings to machines in the same stage are evaluated regarding the buffering capacity and the machine characteristic. We present some numerical results on a simple two stage production system which holds the same number of batches looping. Interesting perspectives for the development of the presented model are looked over.
