现在部署了各种混合的数字-物理(网络-物理)系统，这些系统具有复杂且通常定义松散的组件，其行为对我们的日常生活产生了重大影响，有时甚至是至关重要的。与人工控制和松散耦合的系统相比，计算机物理系统(CP)可以提供更丰富的功能、效率、自主性和可靠性。但是，它们也会造成与底层组件和整个系统的隐私、安全性、健壮性和可靠性相关的固有漏洞。这种系统的数字-物理混合方面为混合设计、建模和分析打开了新的机会，但迄今为止，还没有多少探索的机会。必须设计和部署强大而安全的系统，以应对运营和安全挑战。此外，这些系统的物理组件的连续时间特性意味着适合某些高性能、低功耗的模拟计算解决方案。在这里，我们概述了与此类风险和机会相关的现有努力。我们还将这些主题联系在一起，并为其他对探索混合数字-物理系统的混合方面感兴趣的研究人员提供指导。
A wide variety of mixed digital-physical (cyber-physical) systems with complex and often loosely defined components are now deployed, whose behavior affect our daily lives in significant and sometimes critical ways. Cyber-physical systems (CPS) can provide much richer functionality, efficiency, autonomy, and reliability than manually controlled and loosely coupled systems. However, they also create inherent vulnerability related to privacy, security, robustness, and reliability of the underlying components and as a whole system. The mixed digital-physical aspect of such systems opens new and, as-of-yet, lightly explored opportunities for hybrid design, modeling, and analysis. Robust and safe systems must be designed and deployed to meet operational and security challenges. Additionally, the continuous-time nature of the physical components of these systems implies a fit for certain high-performance, low-power analog computing solutions. Here we survey existing efforts related to such risks and opportunities. We also tie the topics together and provide guidance to other researchers interested in exploring the hybrid aspects of mixed digital-physical systems.
