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...

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...

A warranty policy for a product should balance the interests of both producer and consumer. Consumer protection is typically provided by a guarantee of replacement or some form of repair of the product failing within a promised warranty period, while an approach to provide a corresponding protection for the manufacturer is to limit the maximum usage allowed under warranty. Such warranty policie...

Problem definition : We examine a dynamic assignment problem faced by large wireless service provider (WSP) that is Fortune 100 company. This company manages two warranties: (i) customer warranty the WSP offers its customers and (ii) an original equipment manufacturer (OEM) OEMs offer WSP. The uses devices refurbished OEM as replacement devices, hence their operation closed-loop supply chain. D...

With the help of advanced digital technologies, product managers can use monitored mission cycles to sustain reliability. In this study, a random warranty model and replacement next (RRN) are designed through-life reliability with cycles. The warranty, called two-stage two-dimensional free repair (2DFRW), be carried out during stage. ‘whichever occurs first last’ is used distinguish coverage ra...

In this study, from the user’s perspective, a spare ordering policy for replacement of a non-repairable product/one-unit system, which with finite useful lifetime limit under a rebate warranty, is developed. The spare unit for replacement is available only by an order and the lead-time for delivering that spare is random. By introducing the gain due to rebate warranty, and the costs due to orde...

Abstract: In recent decades, high profits of extended warranty have caused that third-party firms consider it as a lucrative after-sales service. However, customers division in terms of risk aversion and effect of offering extended warranty on manufacturers’ basic warranty should be investigated through adjusting such services. Since risk-averse customers welcome extended warranty, while the cu...

The purpose of this study is to analyze the behavior some industrial systems in light cost-free warranty policy. According policy, we assume that repairman not always present system. When active unit fails, will be called visit system; however, administrative procedures may delay for time. Once on system, first inspects whether fault caused by user or and it repairable not. product laws, carrie...

In this paper, we present an optimal burn-in model for repairable assembly products (RAP) sold under warranty. The general repairable products, sold under warranty and optimal burn-in model by Sheu (2004) are further extended to the case in which the probability of type II failure is independent for a parent item. This paper investigates a parent item (product or system) made up of two items (s...
