Specifying and Reasoning about CPS through the Lens of the NIST CPS Framework
This provides a formal methodology for CPS developers to address system concerns, though it appears incremental as it applies existing ASP techniques to a new domain.
The paper tackles the problem of formally specifying and reasoning about Cyber-Physical Systems (CPS) by introducing a formal definition based on the NIST CPS Framework, and shows that Answer Set Programming (ASP) can precisely formalize and implement solutions for dependency/conflict analysis, issue mitigation, and strategy selection.
This paper introduces a formal definition of a Cyber-Physical System (CPS) in the spirit of the CPS Framework proposed by the National Institute of Standards and Technology (NIST). It shows that using this definition, various problems related to concerns in a CPS can be precisely formalized and implemented using Answer Set Programming (ASP). These include problems related to the dependency or conflicts between concerns, how to mitigate an issue, and what the most suitable mitigation strategy for a given issue would be. It then shows how ASP can be used to develop an implementation that addresses the aforementioned problems. The paper concludes with a discussion of the potentials of the proposed methodologies.
