In this paper, we suggest the k0-renewing replacement warranty (k0-RRW) of a repairable system. Under k0-RRW, the failure of the system up to k0 times is replaced by a new system by the manufacturer and the warranty period will be renewed again. This paper considers the warranty analysis from the manufacturer’s point of view for k0-RRW of a repairable system. To do so, we obtain the expected total warranty cost and the expected total warranty length which are very important information for the manufacturer. The numerical examples are presented for illustrative purpose.
Keywords : k0-renewing replacement warranty, minimal repair warranty, renewing replacement warranty, warranty cost, warranty length.
