In the recent issue of Management Science Fox (Fox, B. 1978. Estimation and simulation. Management Sci. 24 (8, April) 860-861.) expressed doubts about the relevance of steady-state behavior. In a reply Schruben (Schruben, L. W. 1978. Reply to Fox. Management Sci. 24 (8, April) 862.) disagreed on...

Vector computers provide a new tool for management scientists. The application of that tool requires thinking in vector mode. This mode is examined in the context of Monte Carlo experiments with regression models; these regression models may serve as metamodels in simulation experiments. The...

Two simple variance reduction techniques are discussed, viz. antithetic variates and common random numbers. Their joint application creates undesirable negative correlations between the responses of two simulated systems. Therefore three alternatives are considered: antithetics only, common...
