6.8.1 Model, Equations, and Problems

To simplify the problem, a model introduced in [29–31] is adopted. It assumes that only the bottleneck workcenter (BNWC) is of importance, while all other can be viewed as time delays. Since the buffers are infinite, BNWC is easy to identify—this is the WC with the smallest capacity. This leads to the system shown in Fig. 6.28, where each re-entrant path P i , , as well as the input and output paths P 0 and P N , respectively, are delays of duration τ i , (in units of machine cycle time).
