Abstract(s)
Modern industry demands techniques that ensure
the operability of its processes, and even though the exponential
technological advance in the last two decades in the manufacturing
field, failures, waste, and unexpected interruptions are still
present in this sector’s daily routine. Within the Industry 4.0
context, fault-tolerant (FT) production systems remain a complex
issue and sometimes represent a vulnerable aspect. Faulttolerance
techniques dedicated to autonomous and distributed
systems, in a cyber-physical system (CPS) perspective, need to be
investigated to follow the evolutionary pace of the manufacturing
scenarios. This paper overviews these concepts and analyses the
current situation in developing FT for CPS systems through a
systematic literature review. The paper also discusses the research
challenges in this new kind of FT systems due to new distributed
architectures and emerging technologies, matching the several
fault-tolerance phases.
