Reducing warranty servicing costs are of great interest to product manufacturers or, sellers who are contractually bound to provide post-sales support, up to a specified warranty period, usually in the form of some remedial action that restores a failed item to a functioning condition. Here, in the spirit of Jack, Iskandar and Murthy (2009) strategy based on partitioning the effective warranty ...

In this study, we deal with a model to study the effect of PM carried out by both parties on a repairable product sold under a non-renewing, free-repaired warranty policy. During the warranty period, the seller will repair the deteriorated but repairable product and charges no fee to the buyer. After the warranty period, the deteriorated product is also repaired by the seller but the buyer will...

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...

Abstract Background Normal coronary computed tomography angiography (CTA) and positron emission (PET) are associated with an excellent prognosis. Hitherto, data on the warranty period of normal CTA myocardial blood flow (MBF) by PET scarce. Purpose To determine event-free after results. In addition, to whether MBF imaging confers additional prognostic value beyond anatomy in symptomatic patient...

In this paper a stochastic model for a single unit repairable system with Preventive Maintenance (PM) under warranty is analyzed in details by using supplementary variable technique. The cost of repair during warranty is born by the manufacturers, but warranty does not apply to product failure due to user-induced damage such as cracked screen or cracked casing, accident, misuse, physical damage...

Many systems might have a long time dormant period, during which the systems are not operated. For example, most building services products are installed while a building is constructed, but they are not operated until the building is commissioned. Warranty terms for such products may cover the time starting from their installation times to the end of their warranty periods. Prior to the commis...

This paper presents an approach to determine a two-dimensional warranty period for the components, materials and products derived from End-of-Life products to meet components, materials and products demands while minimizing the cost associated with warranty and maximizing the manufacturer’s profits.

This paper addresses the effect of twodimensional warranty policies on the procedure for forecasting the cost of unreliability. Automotive warranties are characterized by age or time in service and vehicle usage mileage. This paper presents a model where the usage time is a primary variable and the mileage accumulation is estimated from field return data. At each time interval the probability o...

In this study, by integrating preventive maintenance (PM) into a two-dimensional warranty region, with customized PM (2D PM) is proposed from the manufacturer’s perspective to reduce cost. The cost of 2D derived. tradeoff between and minimal repair saving obtained choosing proper reliability threshold number PMs, advantage illustrated. Second, post-warranty period, bivariate (BPWM) policy consu...
