currently, a large number of products are being sold with warranty policies. pro-rata warranties are relatively a complex concept. this paper focuses on developing a new pro-rata warranty policy. in this model components of the product are grouped into two disjointed sets, failures of components belonging to set one are covered by prw warranty and those components that belonging to set two are ...

Warranty is a powerful implement for marketing strategy that is used by manufacturersand creates satisfaction for consumers by ensuring to compensate for incorrect operation of the product. Warranty serviceresults ina cost named warranty cost for a manufacturer.This cost is a function of warranty policy, regions, and product failures pattern. Since this service coversthe cost of uncertain failu...

In this paper we describe ongoing research in the areas of maintenance and warranty decision-making for gas turbines used in power plants. We first frame the problem within a larger context of equipment monitoring, diagnostics and maintenance. We then focus on describing and modeling economic issues related to warranty maintenance service from the perspectives of both the consumer (power plant ...

We first frame the problem within a larger context of equipment monitoring, diagnostics and maintenance.

When a repairable product is sold with a free replacement warranty, the manufacturer has the option of rectifying a failure by either repairing the failed item or replacing it with a new one. In this paper, repairs are assumed to be minimal in the sense that they leave the product in exactly the same condition it was in prior to failure. We discuss the form of the optimal repair}replace strateg...

This paper makes a link between opportunistic maintenance literature and warranty analysis of a power plant. A new plant warranty maintenance tasks are observed over a two year period. The main aim is to see how opportunistic maintenance could be incorporated when the warranty period has elapsed. The paper examine the warranty period maintenance task list and propose adequate methods for assess...

Manufacturers supplying products under warranty need a strategy to deal with failures during the warranty period: repair the product or replace it by a new one, depending on e.g. age and/or usage of the failed product. An (implicit) assumption in virtually all models is that new products to replace the failed ones are immediately available at given replacement costs. Because of the short life c...

The paper studies the optimal production run length for a deteriorating production system. The optimal warranty cost is determined by a balance between the warranty cost of the manufacturer and the buyer during its warranty period. It is assumed that the elapsed time until the production process shift is age dependent and arbitrarily distributed. The objective is to minimize the total cost per ...
