Discussion of signature-based models of preventive maintenance

Abstract

First of all, I congratulate the authors in Reference 1 for the pleasant and pedagogical tone in which they exhaustively describe most of the maintenance strategies found in the literature. This fact is a value in itself because it allows both novel researchers and experts having a conceptual map ofmany types ofmaintenance policies which go fromthe seminal work of Reference 2 to the most recent techniques based on the notion of the signature of a coherent system. Specifically, this article is highly recommended for researchers who are interested inmaintenance management strategies for the first time because the authors sequentially list the most relevant results and approaches in the literature, as well as provide a large number of bibliographic citations.
