All-Purpose Screening Procedures for Ranking and Selection

We introduce a framework for designing screening procedures for problems featuring a finite set of simulated systems, a.k.a., ranking-and-selection problems. The procedures guarantee to return either all acceptable systems, or each acceptable system, with high probability, where the definition of acceptability is flexible and can include feasibility with respect to one or more constraints and optimality with respect to one or more objectives. Specifically, the procedures construct separate confidence regions for each system’s performance and search within these regions for a configuration of performances for which a given system is acceptable. By implementing the procedures within a parallel computing environment, their running time can be reduced without compromising screening power. We demonstrate the effectiveness and efficiency of the procedures through numerical experiments.
