Cheng and Kleijnen (Oper. Res. 47(5) (1999) 762) propose a very general regression metamodel for modelling the output of a queuing system. Its main limitations are that the regression function is based on a polynomial and that it can use only one independent variable. These limitations are removed here. We derive an explicit formula for the optimal way of assigning simulation runs to the different design points. (C) 2002 Elsevier Science B.V. All rights reserved.
