Transportation Cyber-Physical Systems: Reliability Modeling and Analysis Framework

AbstractRecently, computation, communication and control are deeply and pervasively embedded into physical and engineered components of transportation Cyber-Physical Systems (CPS). In such systems, the growing complexity of system structure calls for increasing system reliability. Reliability modeling and analysis need not only capture the complex dynamic of transportation systems, but also must be easy to apply, understand and compute. The objective of this paper is to develop a suitable analysis framework to study the structural reliability and connectivity reliability of transportation CPS. We adopt frequency-domain analysis to model the transportation systems reliability. We also discussed how to use our frequency-domain analysis framework to obtain the approximations of complex transportation systems’ reliabilities, which is a future research direction.
