    Abstract

    We propose a periodic preventive maintenance policy for a repairable equipment considering required interval availability. Here the required interval availability is fraction of total operating time over a certain time interval, which is required to accomplish some task by the equipment. The proposed policy gives an optimal preventive maintenance interval that minimizes total expected cost per unit time assuring the required interval availability with a predetermined confidence probability. We derive its mathematical model and apply the policy to a vapor-reflow equipment in a PCB assembly line where minimal repair is performed upon failure. The results show its usefulness compared to conventional periodic preventive maintenance policy.
