PURPOSE:To effectively perform the self-recovery to a failure by use of a case in which recovering work is described. CONSTITUTION:Cases CS1-CS5 are hierarchically classified according to failure symptoms, failures and classes A-B, and a case suitable to a caused failure is selected to conduct recovering work. When the failure can not be recovered by the case application, the work is inferred by qualitative inference to recover the failure. When it is successful, the inferred work is registered as the case of a new class. When the case application results in a failure, application of the cases of the same class is avoided to raise the success ratio of case application. |
