대여 장비에 대한 예방 유지보수 정책의 최적안 결정

Abstract

For leased equipments the lessor incurs penalty costs for failures occurring over the lease period and for not rectifying such failures within a specified time limit. Preventive maintenance action may reduce failures but increase preventive maintenance costs. This paper determines a periodic preventive maintenance policy for minimizing costs when repair time is proportional to the failure intensity function.
