This book provides a detailed introduction to maintenance policies and the current and future
research in these fields highlighting mathematical formulation and optimization techniques. It
comprehensively describes the state of art in maintenance modelling and optimization for
single- and multi-unit technical systems and also investigates the problem of the estimation
process of delay-time parameters and how this affects system performance. The book discusses
delay-time modelling for multi-unit technical systems in various reliability structures
examining the optimum maintenance policies both analytically and practically focusing on a
delay-time modelling technique that has been employed by researchers in the field of
maintenance engineering to model inspection intervals. It organizes the existing work into
several fields based mainly on the classification of single- and multi-unit models and
assesses the applicability of the reviewed works and maintenance models. Lastly it identifies
potential future research directions and suggests research agendas. This book is a valuable
resource for maintenance engineers reliability specialists and researchers as it
demonstrates the latest developments in maintenance inspection and delay-time-based
maintenance modelling issues. It is also of interest to graduate and senior undergraduate
students as it introduces current theory and practice in maintenance modelling issues
especially in the field of delay-time modelling.
