Objectives and problems in simulating computers

Abstract

Because the effort required to simulate a computer system is often very great, analysts should consider carefully the probable value of the results prior to embarking on it. Special languages have been created to aid the programmer in reducing the time required to code a simulation, and analysis techniques are available to reduce time requirements in the later phases of a study. Still, unexpected problems usually arise: An effort concludes with a study only partly completed because budgeted resources have been exhausted, or the results may be of less value than anticipated. If the analyst can foresee problems prior to commencing the detailed coding phase of a study, he can avoid many of the problems, mitigate many of the remainder, and allow for the rest in anticipating the payoffs of the effort.
