Replicative Use Of An External Model In Simulation Variance Reduction, Thomas H. Irish
Replicative Use Of An External Model In Simulation Variance Reduction, Thomas H. Irish
Theses and Dissertations
The use of control variates is a well-known variance reduction technique for discrete event simulation experiments. Currently, internal control variates are used almost exclusively by practitioners and researchers when using control variates. The primary objective of this study is to explore the variance reduction achieved by the replicative use of an external, analytical model to generate control variates. Performance for the analytical control variates is compared to the performance of typical internal and external control variates for both an open and a closed queueing network. Performance measures used are confidence interval width reduction, realized coverage, and estimated Mean Square Error. …
