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...

Nowadays, offering extended warranty is considered as a lucrative source of income from the perspective of the after-sale service providers. Meanwhile, the main concern is presence or absence of base warranty and strategies adopted by the manufacturer during this period. Moreover, extended warranty structure must be responsive and customer oriented, which not only control the services cost but ...

In this paper a redundancy allocation problem is studied where for the first time the supplier selection is taken into consideration and redundant components are provided from appropriate suppliers with the most suitable offers such as discount on buying price of components, warranty length for components, things like that, so that the system reliability, profit and the warranty length proposed...

The Proxel method is a state space-based approach to the simulation of discrete stochastic models. It implements the method of supplementary variables in an algorithmic, rather than mathematical way, without using partial differential equations and is able to solve a wide class of stochastic models. The approach has proven to be very competitive with discrete-event simulation for a class of mod...

This paper proposes a general mixture model framework for automobile warranty data that includes parameters for product field performance, the manufacturing and assembly process, and dealer preparation process. The model fits warranty claims as a mixture of manufacturing or assembly defects (quality problems) and usage related failures (reliability problems). The model also estimates the fracti...

4 Sales delay is the time interval from the date of manufacture to the date of sale. In analysing 5 warranty claims data, the existing research relating to the sales delay has mainly focused 6 on estimating the probability distribution of the sales delay. Longer sales delay may lead 7 to more warranty claims as it can have an impact on the post-sale reliability of products. 8 However, research ...
