다기준 결정모형을 이용한 최적 점검주기 분석연구

초록

Purpose: We developed a multicriteria decision model to assist decision-makers in determining the optimal inspection intervals based on a set of competing criteria, such as cost, downtime, and availability. Methods: A procedure based on multiattribute utility theory is proposed for developing the model. The proposed approach can simultaneously determine the optimal inspection intervals for monitoring the failure behavior of systems trails to be inspected, maintainability features, and decision-maker preferences for cost, downtime, and availability. Results: We determined the optimal inspection intervals for periodic condition monitoring based on delay time analysis and a multicriteria framework. Conclusion: We developed a multicriteria decision model that includes cost, downtime, and availability for consequences that have multiple dimensions to be considered.
