対象品の経歴、履歴等の管理には。Regarding defects, they were not reflected in the future operation schedule of the plant subject to preventive maintenance.In addition, design specification information specific to the equipment and parts that make up the equipment that make up the plant subject to preventive maintenance will change depending on the implementation of periodic inspections. Therefore, unless both periodic inspection performance history information and design specification information are managed at the same time, preventive maintenance activities cannot be carried out at a plant, and information about accidents and defects that have occurred in the past at other plants cannot be managed at plants that are subject to preventive maintenance. It is impossible to reflect this in the future driving pattern schedule. Plants subject to preventive maintenance consist of a huge amount of equipment and parts that make up the equipment, and it is necessary to manage the history and history of items subject to preventive maintenance.
