[en] Facilities should be maintained in solid operational condition and the time required for correcting the malfunctions should be minimized since the operational pause due to malfunctions would be one of the most influencing factors on the accomplishments of research goals. It is well-known that we are able to obtain about a 30% reduction of the disbursement through the scheduled pre-repairing processes and to minimize the duration of the malfunctions provided that the relevant factors were administered under systematic coordination. Hence, the development of the facility integrity management system is necessary in order to minimize the duration of the operational pause due to malfunctions with the least disbursement and to minimize the repair time, and also to maximize the efficiency of the budget execution, manpower organization and maintenance management
