Facilitated by advanced digital technologies, reliability managers can monitor system working cycles during the whole life cycle. Such a technological realization help ensure in real time monitoring cycles. In this paper, incorporating limited random cycle, rebate and charge into warranty theory, free repair with (RFRW-RC) is devised to stage. Under RFRW-RC, removes manufacturers’ responsibilit...

This article studies a performance-based warranty for products subject to competing hard and soft failures. The two failure modes are in the sense that either one, on “whichever-comes-first” basis, can cause product fail. A not only covers repair or replacement of any defect, but also guarantees minimum performance level throughout period. In this article, we propose three compensation policies...

In general, a newly purchased item or system is warranted for a specific period. When the system fails during the warranty period, it is repaired free of charge. Even if the system is repairable, there exists some warranty services under which the manufacturer replaces the failed system during the warranty period. This study considers a case where a manufacturer offers an additional warranty se...

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...

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 ...

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...

In this article, by considering both a limited number of failure replacements and random working cycles as warranty terms, hybrid (HW) is designed from the manufacturer’s point view to warrant product that does successive projects at cycles. The cost produced HW derived analyzed. By defining warrants product, two types post-warranty replacement models are investigated consumer’s ensure reliabil...

This paper considers four options of warranty and preventive maintenance policy. The product is repairable and sold with a non-renewing free warranty policy. For products sold with warranty, preventive maintenance (PM) actions by manufacturers and/or buyers have an impact on the total costs for both parties. In this study, we deal with a model to study the effect of PM that carried out by the m...
