摘要

在这篇文章中,我们提出了一类新的自我意识网络物理系统。通过将网络物理系统和自我意识计算这两个已建立的领域结合在一起,我们的目标是创建具有强大增强但可管理的自主性的系统,这是许多新兴和未来应用和技术的主要要求。自我意识的网络物理系统位于物理环境中,其资源受到限制,它们了解自己的状态和环境,并基于这种理解,能够在运行时以不言自明的方式自主做出决策。为了制定研究议程,我们提出并阐述了未来自我意识网络物理系统的五个关键挑战:(i)我们如何建立对资源敏感但自我意识的系统?(ii)如何认识情境性和主观性?(iii)实施自我意识过程的有效基础设施是什么?(iv)我们如何验证自我意识的网络物理系统,特别是我们可以提供哪些保证?(v) 设计具有自我意识的网络物理系统需要哪些新颖的开发过程?我们详细审查了每一项挑战,并强调,要解决所有这些挑战,就需要系统对形势进行全面评估,并不断反思自身状况,以合理地平衡各种要求、制约因素、短期和长期目标。自始至终,我们引用了三个可能受益于自我意识的网络物理系统的例子:芯片上的多处理器系统、火星车和植入的胰岛素泵。然而,这三个截然不同的系统具有相似的特点:资源有限,复杂的不可预见的环境动态,对其可靠性的期望很高,以及与故障相关的巨大风险。通过这些例子,我们讨论了自我意识在高度复杂和更简单的系统中的潜在作用,作为主要结论,我们强调了对上述主题进行研究的必要性。

Self-aware Cyber-Physical Systems
In this article, we make the case for the new class of Self-aware Cyber-physical Systems. By bringing together the two established fields of cyber-physical systems and self-aware computing, we aim at creating systems with strongly increased yet managed autonomy, which is a main requirement for many emerging and future applications and technologies. Self-aware cyber-physical systems are situated in a physical environment and constrained in their resources, and they understand their own state and environment and, based on that understanding, are able to make decisions autonomously at runtime in a self-explanatory way. In an attempt to lay out a research agenda, we bring up and elaborate on five key challenges for future self-aware cyber-physical systems: (i) How can we build resource-sensitive yet self-aware systems? (ii) How to acknowledge situatedness and subjectivity? (iii) What are effective infrastructures for implementing self-awareness processes? (iv) How can we verify self-aware cyber-physical systems and, in particular, which guarantees can we give? (v) What novel development processes will be required to engineer self-aware cyber-physical systems? We review each of these challenges in some detail and emphasize that addressing all of them requires the system to make a comprehensive assessment of the situation and a continual introspection of its own state to sensibly balance diverse requirements, constraints, short-term and long-term objectives. Throughout, we draw on three examples of cyber-physical systems that may benefit from self-awareness: a multi-processor system-on-chip, a Mars rover, and an implanted insulin pump. These three very different systems nevertheless have similar characteristics: limited resources, complex unforeseeable environmental dynamics, high expectations on their reliability, and substantial levels of risk associated with malfunctioning. Using these examples, we discuss the potential role of self-awareness in both highly complex and rather more simple systems, and as a main conclusion we highlight the need for research on above listed topics.
