초록
Planned maintenance reduces the occurrence of excessive lead times during production or transportation, and prevents large-scale accidents during equipment operation. The probability of failure(Failure-Function) during total life cycle should be considered to establish a maintenance schedule. In this study, we propose an Interval-Optimization- Maintenance. This divides the total life cycle according to the failure probability based on the Failure-Function, and performs an optimized Period-Based-Maintenance in the divided interval. The proposed model has both the convenience of scheduling and prevention of failure. And, the proposed model is a realistic model that can be applied to reality. Failure-Function was derived using the data of the Naval ship and the hierarchical Bayesian estimation method. The results of this study can be used in all industries operating equipment. It is possible to optimize the planned maintenance interval by estimating the Failure-Function of the industrial group and constructing a maintenance model.
Abstract
Planned maintenance reduces the occurrence of excessive lead times during production or transportation, and prevents large-scale accidents during equipment operation. The probability of failure(Failure-Function) during total life cycle should be considered to establish a maintenance schedule. In this study, we propose an Interval-Optimization- Maintenance. This divides the total life cycle according to the failure probability based on the Failure-Function, and performs an optimized Period-Based-Maintenance in the divided interval. The proposed model has both the convenience of scheduling and prevention of failure. And, the proposed model is a realistic model that can be applied to reality. Failure-Function was derived using the data of the Naval ship and the hierarchical Bayesian estimation method. The results of this study can be used in all industries operating equipment. It is possible to optimize the planned maintenance interval by estimating the Failure-Function of the industrial group and constructing a maintenance model.
