Simulation is an important tool for comparing the performance of several alternative systems. There is therefore significant interest in procedures that efficiently select the best system, where best is defined by the maximum or minimum expected simulation output. In this paper, we examine both two-stage and sequential procedures that represent three(More)
An important problem in discrete-event stochastic simulation is the selection of the best system from a finite set of alternatives. There are many techniques for ranking and selection and multiple comparisons discussed literature. Most procedures employ classical frequentist approaches , although there has been recent attention to Bayesian methods. In this(More)
One use of simulation is to inform decision makers that seek to select the best of several alternative systems. The system with the highest (or lowest) mean value for simulation output is often selected as best, and simulation output is used to infer the value of the unknown mean of each system. Statistical procedures that help to identify the best system(More)
We consider how to efficiently allocate computing resources in order to infer the best of a finite set of simulated systems, where best means that the system has the maximal expected performance measure. Commonly-used frequentist procedures that are based on the indifference zone and 'worst possible configuration' tend to suggest an inefficiently large(More)
This article describes some recently-proposed procedures that identify the best simulated system when common random numbers are used. The procedures are based on a Bayesian average-case analysis, rather than a worst-case indifference zone formulation. The procedures allow decision-makers to focus on reducing either the expected opportunity-cost loss(More)
We aimed to illustrate support leg dynamics during instep kicking to evaluate the role of the support leg action in performance. Twelve male soccer players performed maximal instep kicks. Their motions and ground reaction forces were recorded by a motion capture system and a force platform. Moments and angular velocities of the support leg and pelvis were(More)
