Modeling and analytics for cyber-physical systems in the age of big data

In this position paper we argue that the availability of \"big\" monitoring data on Cyber-Physical Systems (CPS) is challenging the traditional CPS modeling approaches by violating their fundamental assumptions. However, big data alsobrings unique opportunities in its wake by enabling new modeling and analytics approaches as well as facilitating novel applications. We highlight a few key challenges andopportunities, and outline research directions for addressing them. To provide a proper context, we also summarize CPS modeling approaches, and discuss how modeling and analytics for CPS differs from general purpose IT systems.
