SYSTEM, METHOD, AND PROGRAM FOR CONTROLLING AT LEAST ONE OF ELEMENTS

摘要

There is provided a system capable of coping with an event which cannot be predicted in advance, without stopping the entire system. The system includes a plurality of elements and a holding unit for holding the value of variable Act reflecting a distance between an evaluation decided by the condition of the system including the plurality of elements and a desired value. The system further includes a decision unit for deciding the next behavior of at least one of the elements according to the variable value Act. The decision unit decides the next behavior in a format controlled by a predetermined rule rather than by a noise as the evaluation approaches the desired value, and decides the next behavior in a format controlled by a noise rather than the predetermined rule as the evaluation gets away from the desired value.
