Resumen

This study aimed to analyze the implementation of Reliability-Centered Maintenance (RCM) in a Peruvian metalworking company to reduce failures in a critical machine, specifically the A10 mill. The research employed a quantitative and experimental design, using document analysis and personal interviews as techniques, along with instruments such as a documentary guide and a questionnaire. Tools such as the criticality matrix, Failure Modes 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 RCM increased the Mean Time Between Failures (MTBF) to 161.2 hours, reflecting an improvement in operational reliability. However, the Student’s t-test yielded a p-value of 0.690, indicating 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.
