This research was developed with the main objective of implementing the MCC methodology to increase the operational availability of escalators in a shopping center, Lima Metropolitana, 2020; For the calculation of availability, the indicators of mean time between failures (MTBF) and mean time to repairs (MTTR) were used. The research developed a methodology of applied type, quantitative approach, explanatory level and experimental design; likewise, the population and sample correspond to 30 escalators in the shopping center. In the development of the experience, functional failures were evidenced that influence the operational availability of the escalators, through the priority risk analysis where problems such as noise in the curve of the handrail, overheating of the brake coil, and contact were identified. chain of steps and the presence of faulty SIF1 fuses, among the most important. From the implementation of the MCC methodology, the comparison of scenarios showed that the MTBF went from 62.98 to 126.5 and the MTTR fell from 5.66 to 4.55 hours, in a complementary way, the economic analysis determines a profitability through the NPV of S / 15,342 soles and the internal rate of return (IRR) of 65.17%. Therefore, availability increased from 91.7% in the average of the period prior to 96.1% in the average of the scenario after the changes. Finally, it is concluded that the MCC methodology increases the operational availability of escalators in the shopping center.
