Abstract
Abstract An information processing system comprises a plurality of systems (1, 3, 4, 6) communicating through a transmission path (2) and performing a processing base on their own function. One of the plurality of systems acts as as an supervising system having a supervising function. The supervising system (1, 4) sets a goal for each of the plurality of systems, collects the processing result on each system and evaluates the processing result; and on the basis of the processing result, the supervising system sets a new goal for each system considering a goal of the entire system comprising said plurality of systems.
