## Abstract

There is provided a maintenance management system including a plurality of operation components that transmit and receive a message and autonomously operate and a message control device that controls the message transmitted and received among the operation components, the maintenance management system maintaining and managing a service. Each of the operation components executes a predetermined action when receiving a message addressed to the operation component and, when the execution of the action is successful, transmits, to a transmission source, a message to which a label allocated to the operation component is given. The message control device receives the message transmitted by the operation component, determines the operation component at the transmission destination from a label given to the transmission source of the message, and transmits the message to the operation component at the transmission destination.

## Claims

### Claim 1

A maintenance management system comprising: a plurality of operation component devices that transmit and receive one or more messages and autonomously operate; and a message control device that controls the one or more messages transmitted and received among the operation component devices, the maintenance management system maintaining and managing a service, wherein
each of the operation component devices executes a predetermined action when receiving a message addressed to the operation component device and, when the predetermined action is successfully executed, transmits, to a transmission source, a message to which a label allocated to the operation component device is given, and
the message control device:
receives the message transmitted by the operation component device;
determines the operation component device at the transmission destination from a label given to the transmission source of the message; and
transmits the message to the operation component device at the transmission destination.

### Claim 2 (depends on 1)

The maintenance management system according to claim 1, further comprising a label management device that allocates labels for each of function types to the operation component devices and manages a relation of labels of transmission destinations with labels of transmission sources, wherein the message control device:
acquires, from the label management device, a label of a transmission destination corresponding to the label given to the transmission source of the message; and
transmits the message to all the operation component devices to which the label of the transmission destination is allocated.

### Claim 3

A message control device that controls a message transmitted and received among a plurality of operation component devices that autonomously operate, the message control device being configured to perform operations comprising:
receiving the message;
determining an operation component device at a transmission destination from a label given to a transmission source of the message; and
transmitting the message to the operation component device at the transmission destination.

### Claim 4 (depends on 3)

The message control device according to claim 3, wherein the message control device:
acquires, from a label management device that manages a relation of labels of transmission destinations with labels of transmission sources, a label of a transmission destination corresponding to the label given to the transmission source of the message; and
transmits the message to all the operation component devices to which the label of the transmission destination is allocated.

### Claim 5

A message control method executed by a message control device that controls a message transmitted and received among a plurality of operation component devices that autonomously operate, the message control method comprising:
receiving the message;
determining an operation component device at a transmission destination from a label given to a transmission source of the message; and
transmitting the message to the operation component device at the transmission destination.

### Claim 6
