The analytic approach appears to be useful in providing approximate stretching factors for storage contention. However, if the desired results must be much more accurate than 10 to 15 percent, it is usually necessary to resort to simulation; the advantages gained through the speed of the analytic technique ordinarily are balanced by its inability to mirror changes in model complexity as readily as simulation.
Skinner et al. (Wed,) studied this question.
