1.3 Maintenance Plan
In production systems, the recovery time can be long, and improvements in system availability cannot
be expected if repairs are considered only after a malfunction occurs.
Therefore, a maintenance plan is developed from when a production system is implemented, and
efficient maintenance is conducted.
In order to quickly restore the system after a malfunction occurs, it is necessary to systematically
execute the contents of the following table.
