Determining the Optimal Software Rejuvenation Schedule via Semi-Markov Decision Process
Software 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...
متن کاملSoftware Vulnerability Patch Management with Semi-Markov Decision Process
Information security incidents frequency has been increasing dramatically, the aim of this study is to analyze the state-space reachability problems through the transition of vulnerable status after the informative system vulnerability exposure. In this research we took into consideration the time factor to analyze the arrival time to reachable states problem discussed in stochastic Petri nets....
متن کاملConstrained Markov Decision Process and Optimal Policies
In the course lectures, we have discussed a lot regarding unconstrained Markov Decision Process (MDP). The dynamic programming decomposition and optimal policies with MDP are also given. However, in this report we are going to discuss a different MDP model, which is constrained MDP. There are many realistic demand of studying constrained MDP. For instance, in the wireless sensors networks, each...
متن کاملStatistical non-parametric algorithms to estimate the optimal software rejuvenation schedule
In this paper, we extend the classical result by Huang, Kintala, Kolettis and Fulton (1995), and in addition propose a modified stochastic model to determine the software rejuvenation schedule. More precisely, the software rejuvenation models are formulated via the semi-Markov processes, and the optimal software rejuvenation schedules which maximize the system availabilities are derived analyti...
متن کاملOptimal Software Rejuvenation for Tolerating Soft Failures Optimal Software Rejuvenation for Tolerating Soft Failures
In recent studies, the phenomenon of software \aging" has come into light which causes the performance of a software to degrade with time. Software rejuvenation is a technique for fault tolerance which counteracts aging. In this paper, we address the problem of determining the optimal time to rejuvenate a server type software which experiences \soft failures" (witnessed in telecommunication sys...
