Selecting a Selection Procedure
Management Science, 2007Selection procedures are used in a variety of applications to select the best of a finite set of alternatives. “Best” is defined with respect to the largest mean, but the mean is inferred with statistical sampling, as in simulation optimization. There are a wide variety of procedures, which begs the question of which selection procedure to select. The

Abstract The libraries of OhioLINK-a large Midwest consortium of all Ohio academic libraries-began an experiment in the purchase and use of e-journals in 1998. Discovering that individual libraries were providing on average only around 25% of the available journal literature from major publishers, the OhioLINK consortium began purchasing all publisher ...
