Cyber-physical systems (CPS) are smart systems that include engineered interacting networks of physical and computational components. CPS and related systems (including the Internet of Things (IoT) and the Industrial Internet) are widely recognized as having great potential to enable innovative applications and impact multiple economic sectors in the worldwide economy.
In mid-2014, NIST established the CPS Public Working Group (CPS PWG) to bring together a broad range of CPS experts in an open public forum to help define and shape key characteristics of CPS, so as to better manage development and implementation within and across multiple “smart” application domains, including smart manufacturing, transportation, energy, and healthcare. The objective of the CPS PWG is to develop a shared understanding of CPS and its foundational concepts and unique dimensions (as described in this “CPS Framework”) to promote progress through exchanging ideas and integrating research across sectors and to support development of CPS with new functionalities. While in principle there are multiple audiences for this work, a key audience is the group of CPS experts, architects, and practitioners who would benefit from an organized presentation of a CPS analysis methodology based on the CPS Framework presented as facets and aspects in this document. The identified key concepts and issues are informed by the perspective of the five expert subgroups in the CPS PWG: Vocabulary and Reference Architecture, Cybersecurity and Privacy, Timing and Synchronization, Data Interoperability, and Use Cases. The CPS analysis methodology is designed as a framework to support the understanding and development of new and existing CPS, including those designed to interact with other CPS and function in multiple interconnected infrastructure environments. This foundation also enables further use of these principles to develop a comprehensive standards and metrics base for CPS to support commerce and innovation. As an example, the CPS Framework could support identification of the commonalities and opportunities for interoperability in complex CPS at scale. The broader audience for this work includes all CPS stakeholders, who may be interested in broadening individual domain perspectives to consider CPS in a holistic, multi-domain context. The first stage in the three-stage work plan of the CPS PWG was to develop initial “Framework Element” documents in each of the five expert subgroups. In the second stage, these documents were combined into an initial draft CPS Framework and then revised and improved to create this draft document. The documented discussions of the subgroups have been included here as Appendices A through C. After public review and finalization of the CPS Framework Release 1, the applicability of this approach will be assessed in selected CPS domains, leading to a planned future road mapping activity to both improve the CPS Framework and develop understanding and action plans to support its use in multiple CPS domains.
