The objective of condition based maintenance (CBM) is typically to determine an optimal maintenance policy to minimize the overall maintenance cost based on condition monitoring information. The existing work reported in the literature only focuses on determining the optimal CBM policy for a single unit. In this paper, we investigate CBM of multi-component systems, where economic dependency exi...

This paper surveys the literature related to maintenance policies for single and multi -unit systems. The emphasis is on work appearing in different periods. The literature is divided into two main categories Single and multiunit system. The single unit system is divided into six sub-categories like: Age-dependent, Periodic, Failure limit policy, Sequential, Repair limit, Repair number counting...

Many industries identify condition monitoring as a major opportunity to reduce maintenance costs and increase equipment availability. This is also the case for the fast emerging offshore wind turbine technology. However, when considering offshore wind turbine farms, implementation of condition monitoring also introduces a significant capital investment cost. Moreover, condition monitoring syste...

Working memory is a limited-capacity form of human memory that actively holds information in mind. Which memories ought to be maintained? We approach this question by showing an equivalence between active maintenance in working memory and a Markov decision process in which, at each moment, a cognitive control mechanism selects a memory as the target of maintenance. The challenge of remembering ...
