Although control principles are not customarily associated with international relations, there may be some significant advantages in seeing how international relations may benefit by suitable use of control concepts and methods. Over the years, control engineers and scientists have learned how to use information processing and equipment, along with energy and materials to improve the performance of various systems.

As is used in connection with systems engineering, a model is a qualitative or quantitative representation of a process or endeavor that shows the effects of those factors which are significant for the purposes being considered. Modeling is the process of making a model. Although the model may not represent the actual phenomenon in all respects, it does describe the essential inputs, outputs, and internal characteristics, as well as provide an indication of environmental conditions similar to those of actual equipment.
