Shipboard Power System Reconfiguration - A Self-Adaptation Exemplar

The Shipboard Power System (SPS) is the component responsible for granting energy to navigation, communication, and operational systems. The SPS Recon guration is the ability to react to electrical failure and to restore critical operations for granting vessel sur- vivability. This work illustrate why SPS Recon guration software system may be implemented as a self-adaptive system. To illustrate this relation we exploit a systematic classi cation of SPS recon guration methods, by highlighting terms and attributes related to self-adaptive systems. In particular, the research method considers four types of self-adaptation systems with di erent de- grees of autonomy and proactivity. The corresponding data analysis highlights a strong correlation between SPS Recon guration and Self-Adaptive systems, revealing most of the SPS recon guration techniques found in literature often belong to three of the four types of adaptation. The outcome of the paper is proposing SPS as an interesting benchmark for comparing self-adaptive approaches, also highlight- ing scenarios, tasks, norms goals and quality aspects with the sup- port of the IEEE speci cations.
