摘要

本文讨论了一种使运行软件系统稳态可用性最大化的基于时间的非周期恢复策略。在固定的周期检查点调度下，提出了一种基于动态规划的最优非周期再生时间求解算法。通过数值算例，给出了系统失效服从威布尔分布时的最优恢复时间及其最大可用性。

Availability optimization in operational software system with aperiodic time-based software rejuvenation scheme

This paper discusses an aperiodic time-based rejuvenation policy maximizing the steady-state system availability in operational software system. Under a fixed periodic checkpoint schedule, we develop an algorithm to derive the optimal aperiodic rejuvenation times based on dynamic programming. In numerical examples, the optimal rejuvenation time and its maximum availability are illustrated in the case where the system failure obeys the Weibull distribution.
