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 problem of determining the optimal warranty period, assumed to coincide with the manufacturer’s lower specification limit for the lifetime of the product, is addressed. It is assumed that the quantity sold depends via a Cobb–Douglas-type demand function on the sale price and on the warranty period, and that both the cost incurred for a non-conforming item and the sale price increase with th...

Using monitored job cycles to design and model random maintenance strategies for ensuring life-cycle reliability has been extensively researched. The heterogeneity over the life cycle ignored universally in this type of strategy. In paper, using two different areas regions that can screen reliability, were customized reliabilities warrantied products with be ensured based on heterogeneity. case...

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...

This paper considers a general repairable product sold under a failure-free renewing warranty agreement. In the case of a general repairable model, there can be two types of failure: type I failure (a minor failure), which can be rectified by minimal repairs; and type II failure (a catastrophic failure), which can be removed only by replacement. After a minimal repair, the product is operationa...

The high cost of lenient return policies force consumer electronics OEMs to look for ways to recover value from lightly used consumer returns, which constitute a substantial fraction of sales and cannot be re-sold as new products. Refurbishing to remarket or to fulfill warranty claims are the two common disposition options considered to unlock the value in consumer returns, which present the OE...

abstract: the profound effect of mgovernment on the future of businesses and communities has been proven in numerous studies. the aim of the present study is provide a model for user requirements and validate the proposed model is based on a literature review of research. the findings suggest that effective and efficient transactions including time, security, privacy, reliability and cost of th...

Warranty service providers usually provide homogeneous warranty to improve consumer satisfaction and market share. Considering the difference of consumers, some scholars have carried out studies on maintenance strategies, pricing, payment method, claim behaviour cost analysis in recent years. However, few focused differentiated coverage that considers usage rate option consumers. On basis previ...
