Modeling and Simulation Techniques for Large-Scale Communications Modeling

Abstract

Because modeling and simulation are so widely used throughout the Army, vast amounts of computer time are used. Of more concern, however, is the quantity of analyst time involved in setting up and analyzing the results of these runs. Increased confidence in the models may be expected to lead to more efficient use of the analyst's time. To this end, an ongoing validation effort for a CECOM model was supported by providing computer routines that measure the degree to which simulation data match test data. Tests of random number generators were also developed and applied to CECOM models. It was found that synchronization of random number strings in simulations is easy to implement and can provide significant savings for making comparative studies. If synchronization is in place, then statistical experiment design can be used to provide information on the sensitivity of the output to input parameters. The report concludes with recommendations and an implementation plan.
