摘要

软件能耗分析是定量形式化方法的一个重要目标。目前的方法使用加权过渡系统或能量博弈,将能源建模为理想资源,其状态由一个数字表征,即剩余能量的数量。然而,真正的电池表现出的行为可能与理想的能源有很大的差异。基于标准连续电池模型的离散化,我们引入了{\em电池过渡系统}。在这个模型中,电池被看作是由两部分组成的——可用充电槽和束缚充电槽。任何充电或放电都适用于可用充电槽。随着时间的推移,每个水箱的能量扩散到另一个水箱。电池转换系统是无限状态系统,由于结构不佳,不属于我们所知的可确定类别。尽管如此,我们能够证明$\omega$-规则模型检查问题对于电池转换系统是可决定的。我们还提出了一个关于能量受限半自主机器人控制程序验证的案例研究。

Battery transition systems
The analysis of the energy consumption of software is an important goal for quantitative formal methods. Current methods, using weighted transition systems or energy games, model the energy source as an ideal resource whose status is characterized by one number, namely the amount of remaining energy. Real batteries, however, exhibit behaviors that can deviate substantially from an ideal energy resource. Based on a discretization of a standard continuous battery model, we introduce {\em battery transition systems}. In this model, a battery is viewed as consisting of two parts -- the available-charge tank and the bound-charge tank. Any charge or discharge is applied to the available-charge tank. Over time, the energy from each tank diffuses to the other tank. Battery transition systems are infinite state systems that, being not well-structured, fall into no decidable class that is known to us. Nonetheless, we are able to prove that the $\omega$-regular model-checking problem is decidable for battery transition systems. We also present a case study on the verification of control programs for energy-constrained semi-autonomous robots.
