SYSTEM OPERATION MANAGEMENT SUPPORT SYSTEM, METHOD AND APPARATUS

摘要

Failure occurrence probability varying with time after prediction occurrence is calculated from a past prediction occurrence situation and a failure occurrence situation. A short-term failure handling cost required for coping with the failure associated with the prediction which has occurred in the system is also calculated from maintenance cost information of a system to be managed in operation. In addition, a first short-term preventive maintenance cost required for preventive maintenance against a failure associated with the prediction is calculated from the past prediction occurrence situation, the failure occurrence situation, maintenance cost information and the failure occurrence probability, and a second short-term preventive maintenance cost is calculated from the failure occurrence probability if preventive maintenance is postponed until the next prediction occurrence. Options in which the first short-term preventive maintenance cost, the second preventive maintenance cost, the failure handling cost and the failure occurrence probability are associated are created and proposed via an output device.
