SIMULATION ERRORS OF HIGH-LOADED SYSTEMS IN GPSS WORLD

Abstract

The article presents research results of random number generators (RNG) influence on simulation accuracy of high-loaded queuing systems in the GPSS World simulation system. It is shown that for certain combinations of RNGs, called problem generators, the inaccuracy of the simulation results of highly loaded systems may reach tens of percent. The analysis of problem combinations revealed factors causing high level of inaccuracy in simulation results.
