Using Operational Analysis in Simulation: A Queueing Network Example
本文展示了如何在排队网络仿真中运用操作分析,通过系统化收集输出数据并计算性能指标,验证假设并引入修正项,从而获得精确的性能度量。
The calculation of certain performance measures in queueing network simulation using operational analysis is presented. A systematic approach to the gathering of output and calculation of performance measures for quantitative system-performance analysis is demonstrated. The assumptions used in operational analysis to derive performance-measure relationships are verifiable by examining the output generated by the simulation. Any errors in assumptions revealed by the output may be measured, and these error measures used to determine correction terms. The performance-measure relations may still be used, even when the assumptions upon which they are based are in error, by adding these correction terms to the performance-measure values obtained. The results will be exact values for the performance measures over the period of the simulation. Calculations of performance measures, error measures and correction terms are illustrated with an example queueing network simulation.
