Application of reliability-centered maintenance to reduce critical machine failures in a Peruvian metal-mechanic company

Abstract

The objective of this study was to analyze the implementation of Reliability Centered Maintenance (RCM) in a Peruvian metal-mechanical company to reduce failures in the critical machine, specifically the A10 mill.The research employed a quantitative and experimental design, using documentary analysis and personal interviews as techniques, together with instruments such as a documentary guide and a questionnaire. Tools such as the criticality matrix, Failure Mode and Effects Analysis (FMEA), Pareto diagram, decision tree and hour counter were used. The Shapiro-Wilk test confirmed the normality of the data with a significance level of 0.365: The implementation of the RCM increased the Mean Time Between Failure (MTBF) to 161.2 hours, reflecting an improvement in operational reliability. However, Student's t-test yielded a p-value of 0.690, indicating that there was no statistically significant difference between the pre- and post-implementation periods. These results suggest a positive but inconclusive impact on failure reduction and reliability.The study highlights the potential of RCM to optimize maintenance resources and improve the availability of critical equipment. However, further analysis and a longer implementation period are needed to obtain statistically significant results and fully validate its effectiveness. Translated with DeepL.com (free version)
