Hit-rate, the percentage of on-time completion, is a very important performance measure in a make-to-order semiconductor fab. This paper presents a dispatching algorithm for such a fab with machine-dedication feature. This feature imposes a constraint on the production route due to the advance of manufacturing technology, and has been rarely addressed in previous literature. A dispatching algorithm, called LBSA, was recently developed for a fab with machine-dedication feature. The LBSA algorithm outperformed many other dispatching methods in terms of hit-rate for short-routing products but not so well for long-routing products. This paper develops a dispatching method that shows a high hit-rate performance for both short-routing and long-routing products.Downloads
