Abstract

The performance of many if not most real-life systems which are simulated depends on two or more factors which can be set at various “levels.” In order to understand the behavior of such a system the experimenter must conduct a factorial experiment in which the behavior of the system is studied at selected factor-level combinations. It is often of interest to select the “best” factor-level combination, i.e., the one associated with the highest average response. The purpose of this paper is to discuss some of the more commonly used statistical selection procedures. Selection procedures appropriate for use with single-factor experiments are considered first. The ideas associated with the use of these procedures are then generalized to two-factor experiments (and implicitly to multi-factor experiments) and new selection procedures for use with such multi-factor experiments are described.
