The accurate estimation of lead times and the use of factory-wide information can improve the performance of dynamic shop floor control. This paper presents a dispatching policy that is based on the concept of bottleneck starvation avoidance and relies on frequently updated queue predictions for all workstations. The queue predictions are used to dynamically estimate the lead times required for lots to reach workstations on their routes, particularly the bottleneck workstation. Object-oriented simulation experiments were run for several wafer fab configurations with results showing a consistantly good behavior of the computationally intensive control mechanism presented here.
