Abstract
In a control system equipped with a plurality of subsystems and a supervising subsystem for supervising these subsystems, a subgoal achievement performance is calculated by the subsystem using its own knowledge and its own condition with respect to a subgoal defined by the supervising subsystem, and the supervising subsystem controls a control system by utilizing the knowledge and conditions of the respective subsystems by applying a subgoal execution instruction to the subsystem based upon the calculation result. Since not only the knowledge but also the condition of the subsystems, proper controls can be realized in not only such a case that the supervising goal is directed to a static temporal aspect, but also such a case that the supervising goal contains a temporal element.
