A comprehensive edited volume exploring the latest in the interactions between cyber-physical systems and humans
In Cyber-Physical-Human Systems: Fundamentals and Applications, a team of distinguished researchers delivers a robust and up-to-date volume of contributions from leading researchers on Cyber-Physical-Human Systems, an emerging class of systems with increased interactions between cyber-physical, and human systems communicating with each other at various levels across space and time, so as to achieve desired performance related to human welfare, efficiency, and sustainability.
The editors have focused on papers that address the power of emerging CPHS disciplines, all of which feature humans as an active component during cyber and physical interactions. Articles that span fundamental concepts and methods to various applications in engineering sectors of transportation, robotics, and healthcare and general socio-technical systems such as smart cities are featured. Together, these articles address challenges and opportunities that arise due to the emerging interactions between cyber-physical systems and humans, allowing readers to appreciate the intersection of cyber-physical system research and human behavior in large-scale systems.
In the book, readers will also find: - A thorough introduction to the fundamentals of cyber-physical-human systems - In-depth discussions of cyber-physical-human systems with applications in transportation, robotics, and healthcare - A comprehensive treatment of socio-technical systems, including social networks and smart cities
Perfect for cyber-physical systems researchers, academics, and graduate students, Cyber-Physical-Human Systems: Fundamentals and Applications will also earn a place in the libraries of research and development professionals working in industry and government agencies.
