RT annotation T1 Discussion of signature-based models of preventive maintenance A1 Suárez Llorens, Alfonso A2 Estadística e Investigación Operativa AB First of all, I congratulate the authors in Reference 1 for the pleasant and pedagogical tone in which they exhaustivelydescribe most of the maintenance strategies found in the literature. This fact is a value in itself because it allows bothnovel researchers and experts having a conceptual map ofmany types ofmaintenance policies which go fromthe seminalwork 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 firsttime because the authors sequentially list the most relevant results and approaches in the literature, as well as provide alarge number of bibliographic citations.
