Many services products are installed in a complex system that is operated only when the entire system is completed. The time from their installation to commissioning, called a dormant state in this paper, may take several years for systems such as complete buildings or aircraft. Warranties for the products may cover the time starting from their installation to a certain time. Warranty cost on r...

This paper analyses life cycle cost for equipment protected by both base and extended warranty policies from a consumer’s perspective. We assume that the equipment have two types of failures: minor and catastrophic. A minor failure can be corrected by a minimal repair whereas a catastrophic failure can only be removed by a replacement. The equipment is assumed to be maintained at no charge to t...

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...

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...

Employing remanufactured and refurbished products are among the new strategies that companies used to raise their profits as well as protects environment. Although used product equipment gives an opportunity to purchase latest technology, customers are doubtful about quality and reliability of these products. Because of limitation that developing countries faces in buying new products, some cou...

In the present academic and engineering fields, every measure function of product reliability is modeled estimated from statistical perspective. These indicate that there universally exist differences in reliabilities new identical products survive burn-in test. On basis products, designing through-life maintenance models for managing different a very practical topic fields. this study, random ...

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...

The environmental sustainability and business benefits of end-of-life products have led to worldwide growth in the remanufacturing market. However, customers are often sceptical about quality durability remanufactured products. To ensure a risk-free customer experience, dealers carry out some upgrading actions on most critical components offer reasonable warranty period at time resale. It is cr...

Due to the imperfection of processes, quality some products may be unsatisfactory. Moreover, equipment failure can stop production for a while. Therefore, integrating triple concepts quality, maintenance, and inventory control has attracted attention. Triple are constituents pre-sale costs. Selling price warranty generally considered maintain market share maximize producer's profit. Quality mai...
