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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
141 words
A power distribution route control system comprising a plurality of control devices dispersed in the power distribution route, each control device collections and processing information in the power distribution route and providing a control command for said power distribution route to the other control devices, wherein when a first state in the power distribution route changes, the control device having first detected the first state change offers said control command to the other control devices and when a second state change occurs, after said first state change has occurred and at a point other than a point of the power distribution route where the first state change has occurred, the control device which first detects the second state change among the control devices in a neighborhood where the second state change occurs offers the control command to the other control devices.
Claim 2
Dependent Claim
141 words
A power distribution route control system comprising a plurality of control devices dispersed in the power distribution route, each control device collections and processing information in the power distribution route and providing a control command for said power distribution route to the other control devices, wherein when a first state in the power distribution route changes, the control device having first detected the first state change offers said control command to the other control devices and when a second state change occurs, after said first state change has occurred and at a point other than a point of the power distribution route where the first state change has occurred, the control device which first detects the second state change among the control devices in a neighborhood where the second state change occurs offers the control command to the other control devices.
Claim 3
Dependent Claim
40 words
A power distribution route control system according to claim 1, wherein at least one of a voltage, a current, a phase, a switching state in a switch, and information of a failure point is transferred via said power distribution route.
