在本文中，我们构建了考虑恢复操作数量的软件可用性模型。我们将软件系统的故障和恢复特征与已纠正故障的累积数量相关联。此外，我们考虑了一个不完善的调试环境，其中检测到的故障并不总是被纠正并从系统中删除。系统在上升和下降状态之间交替的时间相关行为由马尔可夫过程描述。从这个模型中，我们可以考虑恢复操作的数量来得出软件可用性评估的定量度量。最后，我们展示了软件可用性分析的数值示例。关键词: 软件可用性, 不完善调试, 软件
In this paper, we construct a software availability model considering the number of restoration actions. We correlate the failure and restoration characteristics of the software system with the cumulative number of corrected faults. Furthermore, we consider an imperfect debugging environment where the detected faults are not always corrected and removed from the system. The time-dependent behavior of the system alternating between up and down states is described by a Markov process. From this model, we can derive quantitative measures for software availability assessment considering the number of restoration actions. Finally, we show numerical examples of software availability analysis. key words: software availability, imperfect debugging, software
