Modeling in performance-enhancing processes

The original concept for this paper comes from my 1994 Omega Rho lecture in which I described the concept of a Factory-in-the Computers(C) as a set of models, primarily simulation-based, that could be embedded in a manufacturing system and be a part of an executive decision support system. In attempting to write a paper based on this Omega Rho presentation, it became evident that it was necessary to include information on basic processes related to the use of modeling and simulation. The end result was the writing of a paper which addresses the process for enhancing performance and issues related to the use of modeling in such processes.
