Revista de Ingeniería en Mantenimiento, Confiabilidad y Excelencia Operacional

It is with great pleasure that we present the second issue of RIMCEO, the Journal of Maintenance Engineering, Reliability, and Operational Excellence of the Department of Mechanical Engineering at the Federico Santa María Technical University. This issue features seven articles on applications of reliability, maintenance, and risk analysis in various industrial sectors.

In the natural gas processing sector, two papers examine normalized maintenance cost as a management indicator and the reliability of a compression fleet using the Crow-AMSAA model. A third article presents an FMECA methodology that incorporates climate risk into electrical distribution assets.

This issue also includes experimental research on the first critical speed of a centrifuge, a qualitative analysis of criticality in subsystems of an astronomical observatory, and an application of root cause analysis to a vertical impact crusher in the aggregates sector. The seventh paper addresses criticality and risk in comprehensive reliability using advanced analytics.

These articles show how engineering methods can provide evidence to improve decisions regarding maintenance, investment, and asset management. We thank the authors, reviewers, and contributors who made this issue possible, and we invite the academic and professional community to explore these findings.
