Abstract

Software rejuvenation is a proactive maintenance technique adopted in diverse and wide applications for mitigating performance deterioration effects of software aging and further preventing the system crash from happening. As the software rejuvenation procedure incurs system overhead and downtime, it is relevant and crucial to optimize the software rejuvenation policy to maximize its benefit and effectiveness. This work considers the optimal rejuvenation policy problem for systems subject to multiple performance degradation levels and performing real-time tasks. The solution encompasses a new iterative method for time-dependent evaluation of the task successful completion probability for the considered real-time systems, enriching and expanding the existing evaluation methodologies for software aging and rejuvenation systems. Based on event transitions, the proposed evaluation method is efficient and applicable to arbitrary types of state transition time distributions. The state-based rejuvenation policy is further optimized to maximize the probability of the task completion by the predetermined deadline. Examples are provided to illustrate applications of the proposed methodology as well as effects of different system parameters on the optimization solution.
