ABSTRACT
In system dynamics, especially analyses of physical phenomena, an analytical approach that investigates an interaction mechanism or mechanical structure of a system, which is composed of an enormous number of homogeneous elements such as atoms or molecules, is usually based on statistical analysis methods. On the other hand, in systems engineering, a method of deterministic description of the interaction of a small number of degrees of freedom has been adopted to investigate system performance. However, such analysis is difficult for both a system with a large number of degrees of freedom that can be analyzed with statistics and a system with a small number of degrees of freedom that can be deterministically treated; a class of medium-sized systems in terms of degrees of freedom has great difficulty analyzing the interaction mechanism among elements and the total system performance.
