We describe a discrete event simulator that has been deployed in a 300 mm wafer fabrication plant to aid short-term, operational decision-making. Our simulator has been designed and calibrated to produce reliable predictions over simulation horizons as short as a few days to several weeks. It...

The performance in many companies is limited through bottlenecks in manufacturing and assembly processes. For this reason, bottlenecks are often the starting point of improvement initiatives. This paper presents a visual approach for identification and evaluation of bottlenecks to ease the...
