In this study we propose an approach of quantifying the risks of misinforming and malfunctioning aiming to assess the quality of a warranty policy. We identify the “quality” of a warranty policy as an integral measure, based on the balance between two types of warranty – the warranty of malfunctioning and warranty of misinforming. This measure is represented in terms of the length of the warran...

Wei Huang: Managing Warranty Services: Pricing, Inventory and Outsourcing (Under the direction of Jayashankar Swaminathan, Vidyadhar Kulkarni) Managing warranty services plays a very important role in today’s business environment. This thesis concentrates on three specific areas related to warranty: joint control of new and warranty parts inventory, outsourcing of repair services, coordinated p...

We consider the problem of outsourcing warranty repairs to outside vendors when items have priorities in service. The manufacturer has a contract with a fixed number of repair vendors. The manufacturer pays a fixed fee for each repair done by a vendor which is independent of the repair type and priority class but depends on the vendor. There are a fixed number of items under warranty, and each ...

Purpose: In this paper, the minimal repair-replacement warranty policy is used to carry out a warranty cost analysis with warranty servicing times and failure times that are statistically correlated to bivariate distributions. Methods: Based on the developed approach by Park and Pham (2012a), we investigate the property of the Freund’s bivariate exponential distribution and obtain the number of...

For repairable items sold with free replacement warranty, the actions available to the manufacturer to rectify failures under warranty are to (1) repair the failed item or (2) replace it with a new one. A proper repair-replace strategy can reduce the expected cost of servicing the warranty. In this paper, we study repair-replace strategies for items sold with a two-dimensional free replacement ...

Amongst the many approaches in modelling deteriorating systems with product warranty, renewing warranty has found favor in designing such systems. In this chapter our attention is focused on renewing warranty policy modelled using quasi-renewal inter repair times. With the basic classification of warranty policies viewed in the previous chapters, the warranties are further categorized as renewi...

Facilitated by advanced digital technologies, reliability managers can monitor system working cycles during the whole life cycle. Such a technological realization help ensure in real time monitoring cycles. In this paper, incorporating limited random cycle, rebate and charge into warranty theory, free repair with (RFRW-RC) is devised to stage. Under RFRW-RC, removes manufacturers’ responsibilit...
