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 ...

Automobile warranties and thus lifetimes are characterized in the two-dimensional space of time and mileage. This paper presents a non-homogenous Poisson Process (NHPP) predictive model for automobile warranty claims consisting of two components: a population size function and a failure or warranty claim rate. The population size function tracks the population in the time domain and accounts fo...

Glass relaxation occurs in a range of temperature during transition from equilibrium to super-cooled liquid. Viscoelastic material model can be applied to simulate glass behavior in the glass transition regime. COMSOL Multiphysics software 4.3b can simulate the stress relaxation with the WLF (WilliamsLandel-Ferry) shift function, but no structural relaxation. In this study we developed a framew...

5.1 INTRODUCTION Up to now, warranty cost models for new products have been analyzed. In view of the present day market, customers are more attracted towards the secondhand products. Thus the present and the succeeding chapters of this thesis focus on analyzing the secondhand products by providing two-dimensional warranty for such products. A two-dimensional warranty policy is characterized by ...

The cost of servicing a warranty depends, amongst other factors, on the type of repair performed under warranty. Although ‘‘all minimal repair’’ and ‘‘all replacement’’ policies are easy to implement and analyze, they are not always feasible and/or practical. Having a combination of different types of repair often leads to lower warranty servicing costs. In this article, to reduce the warranty ...

Most companies seek efficient rectification strategies to keep their warranty related costs under control. This study develops and investigates different repair strategies for oneand two-dimensional warranties with the objective of minimizing manufacturer’s expected warranty cost. Static, improved and dynamic repair strategies are proposed and analyzed under different warranty structures. Numer...

Lifetime warranties is becoming popular as they provide assurance to buyer for longer reliable service and greater customer peace of mind for the whole life of the product. By offering a lifetime warranty, both the manufacturer and the buyer are exposed to uncertainties and risks of warranty pricing and product performance during the lifetime of the product. This paper analyses the sensitivity ...
