document: Optimal allocation of runs in a simulation metamodel with several independent variables Cheng and Kleijnen -LRB- 1999 -RRB- 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
