Warranty system-cost analysis using quasi-renewal processes

Abstract

In this paper, we present two alternative quasi renewal processes based on the quasi-renewal process recently developed by Wang and Pham [17]. The first alternative process is an altered quasi-renewal process with random parameter and the other is a mixed quasi-renewal process considering replacements and repairs. These mixed and altered quasi-renewal processes are used for developing the warranty cost models, reliability and other measures for k-out-of-n systems. A numerical example is discussed to demonstrate the applicability of the proposed methodology.
