1.1 Introduction

Cyber Physical Systems (CPS), according to a definition provided by National Science Foundation (NSF) are hybrid networked cyber and engineered physical elements co‐designed to create adaptive and predictive systems for enhanced performance. These systems are built from, and depend upon, the seamless integration of computation and physical components. Advances in CPS are expected to enable capability, adaptability, scalability, resiliency, safety, security, and usability that will expand the horizons of these critical systems.

CPS engineering is an activity that brings these elements together in an operational scenario. Sometimes, an operational scenario may span multiple domains, for example, Smart Grid incorporating Power critical infrastructure and Water infrastructure. Intelligent home devices such as a smart washing machine utilize both the infrastructures. Another example would be Smart Transportation system wherein intelligent transportation devices interact with numerous smart vehicles to coordinate large scale traffic behaviors. Numerous such examples exist within the Internet of Things (IoT) perspective. These complex systems involve components at varying level of specifications. The constituent elements are supplied by multiple vendors ...
