Abstract

PURPOSE:To reduce the burden of maintenance work to a maintenance man and to improve the reliability by storing an allowable failure occurrence limit of each part where failure occurs and each article and reporting the occurrence of failure at the time of arrival of the failure occurrence state of the part at this limit. CONSTITUTION:A computer system 1 is diagnosed by the instruction or the like of a self-diagnosis part 4; and if abnormality information is analyzed and arranged by an abnormality information management control part 5 with respect to each function block and each degree of importance, and results are sent to a reliability information storage part 6. Since the number of times of abnormality occurrence allowed for each function block is stored as reliability information in the reliability information storage part 6, this abnormality information and reliability information are compared with each other to output results instructing whether detailed diagnosis is necessary or not or the instructing of a need of parts replacement or the like. Thus, the maintenance man refers to this instruction to take a required countermeasure, and the maintenance work is reduced and automatized to improve the reliability.
