Common random numbers (CRN) is a widely-used technique for reducing variance in comparing stochastic systems through simulation. Its popularity derives from its intuitive appeal and ease of implementation. However, though CRN has been observed to work well with a broad range of models, the class...

We consider tandem queueing networks with no waiting spaces and address the issue of ordering the stations so that the throughput (i.e., the departure rate) is maximized. Based on some theoretical and extensive empirical results, we propose two rules for ordering the stations. The first rule...

Consider a job shop that is modelled as an open queueing network of the Jackson (Jackson, J. R. 1957. Networks of waiting lines. Oper. Res. 5 518--521.) type. All work stations in the shop have the same number of parallel servers. Two problems are studied: the loading of stations and the...
