To automatically achieve restoration from the occurrence of a failure.

A failure monitoring and reporting device 130 detects a failure occurring in a computer system, reports it to a maintenance status monitoring device 140, collects all logs, and sends them. An analysis device specifies a cause of the failure and suspicious parts based on the logs for output. A physical distribution device searches for the stock of the parts and sends a replacement procedure manual to the terminal of a maintenance person. Also, the maintenance person arranges for the parts so that the parts arrive on the determined date of treatment. Once these operations complete, the maintenance status monitoring device 140 registers the completion of the operation and the analysis device 100 updates an example database 104 if necessary.
