Abstract
In this paper, two-factor warranty policy is investigated considering the preventive maintenance (PM) services in the warranty period using failure times and warranty servicing times from the manufacturer's perspective. Under the warranty, the replacement service is considered as well as the repair service for a failed product as warranty services and the PM service is scheduled for system's quality and reliability in the warranty period. If a failed product could not be repaired by the threshold time limit in the warranty service center, the replacement service is provided instead of continuing to provide repair service in the model and using Jung and Park's maintenance model, the maintenance policy is investigated with a preventive replacement service during the warranty period [1]. In this study, an optimal maintenance policy is proposed considering two-factor warranty to find the optimized preventive maintenance interval in terms of an expected cost rate. Free replacement/repair warranty and pro-rata warranty are also considered in the paper. The real application is implemented using the proposed approach by field data and numerical examples are discussed to exemplify the applicability of the methodologies derived in this paper.
