Yes / Diagnostics and prognostics have significant roles in the reliability enhancement of systems and
are focused topics of active research. Engineered systems are becoming more complex and are
subjected to miscellaneous failure modes that impact adversely their performability. This everincreasing
complexity makes fault diagnostics and prognostics challenging for the system-level
functions. A significant number of successes have been achieved and acknowledged in some
review papers; however, these reviews rarely focused on the application of complex engineered
systems nor provided a systematic review of diverse techniques and approaches to address the
related challenges. To bridge the gap, this paper firstly presents a review to systematically cover
the general concepts and recent development of various diagnostics and prognostics approaches,
along with their strengths and shortcomings for the application of diverse engineered systems.
Afterward, given the characteristics of complex systems, the applicability of different techniques
and methods that are capable to address the features of complex systems are reviewed and
discussed, and some of the recent achievements in the literature are introduced. Finally, the
unaddressed challenges are discussed by taking into account the characteristics of automotive
systems as an example of complex systems. In addition, future development and potential research
trends are offered to address those challenges. Consequently, this review provides a systematic
view of the state of the art and case studies with a reference value for scholars and practitioners.
