Cyber-physical systems challenges: a needs analysis for collaborating embedded software systems

Pieter J. Mosterman, Justyna Zander
2015 Journal of Software and Systems Modeling  
As product features came to increasingly rely on software, a network infrastructure helped factor out common hardware and offered sharing functionality for further innovation.  ...  The intent is to contribute to a model-based research agenda in terms of design methods, implementation technologies, and organization challenges necessary to bring the next generation systems online.  ...  This sharing mechanism contributes to such a tight integration that the systems become one emerging CPS as a system of systems. The result is illustrated in Fig. 1(c) .  ...
