Warranty cost analysis using alternating quasi-renewal processes with a warranty option

Modelling of deteriorating systems with preventive repair during warranty using geometric processes was carried out in the previous chapter. In this chapter the independent and identically distributed assumption of geometric processes is relaxed to assume only the independent successive inter arrival times. Surveying the literature, one is struck by the fact that there has been so little research focusing on the consideration of non-negligible repair times during warranty. Owing to the importance of product warranty, this chapter deals with extended warranty using non-negligible repair times based on quasi-renewal processes.
