The article explores how giving priority to certain "hot lots" in semiconductor manufacturing can impact overall performance. By using a simulation model of a wafer fabrication facility, the researchers found that expediting hot lots can increase costs for the fab. They suggest decision makers consider the additional profit needed per hot lot to offset these costs and determine the maximum allowable expediting cost per period.
