Specify optimal repair replacement strategy in warranty region by minimizing total expected warranty servicing cost Masoomeh Mansouri Bidkani masoomemansouri@yahoo com 1388 1 30 Department of Industrial Systems Isfahan University of Technology Isfahan 84156 83111 IranDegree M ScZeinal Hamadani A hamadani@cc iut ac irMollverdi N naserm@cc iut ac irAbstract An important problem facing manufacturers in today s competitive market is thedetermination of the warranty period of a product and its repair replacement strategy fordefective product in warranty period A warranty is an assurance given by the seller at the time of sale that the product willperform its functions satisfactorily for a specified time period which requires themanufacturer to rectify all item failures either through repair or replacement should failureoccur within the period specified in the warranty As a result offering warranty implies anadditional cost to the manufacturer and this cost depends on the servicing strategy For repairable items the manufacturer is required to rectify all item failures throughminimal repair replacement and imperfect repair should failures occur within the periodspecified in the warranty We focus on a particular warranty repair strategy related to the degree of the warranty repair for non renewing two dimensional free of charge to the consumer warranty policy Weconsider a rectangular warranty region and divide it into three disjoint subregions so thateach of these subregions has a preassigned degree of repair for a faulty item Our main goal isto determine the subregions so that the associated expected warranty servicing cost per itemsold is minimized Two dimensional problem is effectively reduced to a one dimensionalproblem by treating usage as a random function of age Key words warranty failure Non Homogeneous Poisson Process renewal process usagerate repair replacement
