PROBLEM TO BE SOLVED: To solve such problems that if it is not determined to be in multiple occurrence state, the occurrence trend of failures cannot be known without following history information one by one in detail and that the indication of the multiple occurrence state is hardly confirmed although measures can be taken in advance if the indication of the failure multiple occurrence state is known in advance in such a case of periodical inspection. SOLUTION: In history display of the failure information, a management system calculates the difference value of occurrence time information from the previous failure information for each piece of the failure information and determines whether the value is below a preset threshold value or not. For abnormal information where the difference value is determined to be below the threshold value, the system edits to display data indicating the failure information in a list format with visually distinguishing as one above the threshold value.
