Abstract

We develop two sequential procedures to compare a finite number of designs with respect to a single standard. The goal is to identify a good design, and ensure that the standard is chosen when other alternatives are not better than the standard. We give preference to the standard since there are costs and time involved when replacing the standard. These procedures can be used when the expected performance of the standard is known or unknown, when variances across designs are unequal, and with the variance reduction technique of common random numbers. An experimental performance evaluation demonstrates the validity and efficiency of these sequential procedures.
