This paper discusses the validity of using common random numbers (CRNs) with two-stage selection procedures to improve the possibility of correct selection and discusses the intrinsic subset pre-selection of the <i>Enhanced Two-Stage Selection</i> (ETSS) procedure. We propose using CRNs with <i>Rinott's two-stage selection</i> and ETSS procedures when the(More)
Multiple independent streams of random numbers are often required in simulation studies, for instance, to facilitate synchronization for variance-reduction purposes, and for making independent replications. A portable set of software utilities is described for uniform random-number generation. It provides for multiple generators (streams) running(More)
This paper discusses implementation of a two-stage procedure to determine the simulation run length for selecting the best of <i>k</i> designs. We purpose an <i>Enhanced Two-Stage Selection</i> (ETSS) procedure. The number of additional replications at the second stage for each design is determined by both the variances of the sample means and the(More)
Two-stage selection procedures have been widely studied and applied to determine appropriate sample sizes for selecting the best of k designs. However, standard " indifference-zone " procedures are derived with a statistically conservative least-favorable-configuration assumption. The Enhanced Two-Stage Selection (ETSS) is a procedure that takes into(More)
