In this paper we study the distributional properties (mean, variance, characteristic function) of the discounted warranty cost (DWC) for general warranty programs including free replacement (FRW) pro rata (PRW) and FRW/PRW in the context of perfect repair. Since only failure times and types are needed in the derivation of these properties, the reliability of the systems is modeled according to ...

During extended warranty (EW) period, maintenance events play a key role in controlling the product systems within normal operations. However, modelling of failure process and optimization is complicated owing to complex features system, namely, components multi-component system are interdependent with each other some form. For purpose optimizing EW pricing decision scientifically rationally, t...

A new maintenance policy which minimizes the total expected servicing cost for an item with two–dimensional warranty is proposed. An iterative procedure to estimate the item’s failure rate function from historical observations and an optimization algorithm based on Monte Carlo simulation are applied to obtain the best maintenance policy. Numerical examples and sensitivity analysis are presented.

It is known that machinery in agriculture used to perform work optimal agricultural terms under difficult conditions, which requires constant improvement of approaches determining the technical condition. Technical service main and most effective measure ensures maintenance machines working condition during life cycle. At same time, order objectively determine machine, it necessary obtain an ap...

Abstract Standard life cycle techniques such as warranty cost (LCWC) analysis and (LCA) are used to respectively quantify the relative economical environmental advantages of remanufactured goods while simultaneously identifying avenues for improvement. In this paper, we contribute literature on studies by incorporating reliability into LCWC LCA with goal improving long-term/multiple decision ma...

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...

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...

In this study, a new warranty service strategy is proposed and analyzed. This strategy adds the renewing free-replacement warranty to a non-repairable product sold under the rebate warranty policy. According to the renewing free-replacement warranty, the seller (manufacturer) is responsible for replacing all failed product during the warranty period, and the warranty begins anew with each repla...
