| Summary: | 碩士 === 東海大學 === 數學系 === 92 === This research is the continuation of studies about the flow-control technique of WIP scatteration in wafer fabrication. We hope these techniques will be understood and discussed in the future. First, except for rewriting the previous methodologies on wafer release and dispatching, this research also emphasizes on the advantage of such structure of dispatching on macro procedure management from the queuing theory point of view. In addition, the research adds several designs that can increase the bottleneck machines utilization rate. Take the second experimental procedure as an example; its yearly throughput of the related single-process operating system has increases 7.9% over the original technique. At last, other than the traditional procedure control technique in terms of its production planning and scheduling, and then instruct lower level wafer releasing and dispatching methods, our methodology goes in the opposite way: having the releasing and dispatching designs first, and then take it as a base to direct related production planning Such a methodology yielded many developmental potential. The study above is done by Miss. Chang and I. We share the same results of the study but branch out in writing up the theses. Miss. Chang puts stress on the explanation and correction for the flow-control technique of WIP scatteration. I emphasize on the literature comparison and practical explanation for the reverse releasing and dispatching productive scheme.
