Selling simulation and simulation results [PDF]

open access: yesProceedings of the 24th conference on Winter simulation - WSC '92, 1992
Selling simulation as a valid analysis tool is the first, and maybe the most important, step in the simulation process. Once the decision has been made to use simulation, the analyst must then be concerned with selling the ultimate results produced by the simulation.
