Research ArticleOpen accessIn the abstractDetermining the Optimal Software Rejuvenation Schedule via Semi-Markov Decision ProcessHiroyuki Eto, Tadashi DohiSoftware rejuvenation is a preventive and proactive maintenance policy that is particularly useful for counteracting the phenomenon of software aging. In this study we consider an operational software system with multiple degradations and derive the optimal software rejuvenation policy minimizing the expected operation cost per unit time in the steady state, via the dynamic programming approach. Especially, we show analytically … …Journal of Computer Science, Vol. 2, Issue 6 · 30 Jun 2006 · 6,976 accessesView PDFCite
