Usually the warranty data response used to make predictions of future failures is the number of weeks (or another unit of real time) in service. Use-rate information usually is not available (automobile warranty data are an exception, where both weeks in service and number of miles driven are available for units returned for warranty repair). With new technology, however, sensors and smart chip...

Prognostics and Health Management (PHM) is a methodology that permits the assessment of product reliability and the prediction of remaining useful life (RUL) under life-cycle conditions through continuous monitoring. This paper addressed a unique use of PHM for business warranties. PHM is able to help understand what went wrong quickly and exactly in a product. PHM will assist companies to make...
