Description

{SYSTEM AND FOR THE ESTABLISHMENT AND MANAGEMENT OF FAILURE CLASS TABLE (DEFENDING ON EQUIPMENT CLASS USING FAILURE INFORMATION MASTER TREE (FIMT)}}

The present invention relates to a fault classification table generation system for each facility type using a fault information master tree. More particularly, the present invention relates to a system for generating a fault classification table (FCT) for each facility type by constructing a fault information master tree (FIMT) The present invention relates to a technique for providing a change in systematic FCT using a FIMT when a failure classification table (FCT) is changed.

Nuclear power plants use the Preventive Maintenance Template to perform preventive maintenance. Preventive maintenance standards are categorized by facility type, so the period of forecast / preventive maintenance activity is also determined by the type of equipment and the importance of equipment.

An important feedback element in the operation of PMT is the reflection of the failure maintenance result. In other words, according to the information of the cause of the failure in a certain part of the device as a result of the failure maintenance, the maintenance to prevent such repetitive failure is reflected in the PMT and the appropriate period is determined.

However, the conventional fault classification table of nuclear power plants was limited to general causes for mechanical, electrical, and instrumentation, and detailed information on the fault site could not be confirmed and information on the cause of the fault that occurred in a specific fault site was not provided . Also, there was no fault classification table according to the type of facility.

For this reason, there was a difficulty in inputting faults for each type of facility, and therefore, the reliability of the collected equipment was also raised as a problem.
