PURPOSE:To effectively perform the self-recovery to a failure by use of a case in which recovering work is described. CONSTITUTION:Cases are hierarchically classified according to failure symptoms, failures and classes, and a case suitable to a caused failure is selected to perform recovering work. In the application of the case, the case is corrected at need. When the work ends in a success by the corrected case, the corrected case is registered to the same class as the original case to complete the cases. Application priorities are given to the classes, and when the applicable case is present in plural classes, the application priorities are referred to at need. When the application of the case is successful, the application priority of the related class is raised to properly cope with a failure occurring from the same cause. |
