Abstract
Recently, manufacturing systems have become large scale and complex. Social scientific approach is one of the promising methods to facilitate effective operation for the resource allocation problems in manufacturing systems, since the approach takes an analogy of social systems with optimality and robustness in nature. In this paper, we firstly propose a modelling methodology of oligopolistic virtual market, and develop an oligopolistic virtual market as an experimental model. Then we clarify the several important characteristics of the oligopolistic virtual market by computer simulation experiments, and try to apply the proposed method into a utility computing operational problem to validate its effectiveness into resource allocation problems.
