The general objective of this job is to implement the RCM and Lean Maintenance methodologies to increase the availability of production of the Tara Powder mills. During the year, the Average availability percentage is 67%. However, the target availability is of 90%, making the technical Gap a 23% (90%-67%). This technical Gap Generates an economic loss which can be associated with the unproductive time spend by the company reaching a total of S/ 808,141.95, which represents 7% of the annual turnover of S/ 11,245,857.00. In this context, the company is challenged to implement efficient maintenance strategies, such as Reliability Centered Maintenance (RCM) and Lean Maintenance by using Improvement tools like Poka Yoke and Andon. The reliability of the system is calculated before the implementation of the Methodologies which result in the MTBF of 13.20 hours that indicates, on average, the system as a whole can operate during that period before experiencing a failure, suggesting moderate reliability. Finally, the MTTR of 6.57 hours represents the average time required to repair this equipment after a failure, which is relatively a short time and will help minimize downtime. The root cause analysis is carried out, being the main cause of electrical failures, which represents 34.46%. Other important causes that directly related to mechanical failures, include parts or pieces of equipment breaking to a 19.72%, Clogging due to wet Tara is a 9.55%, and a 9.06% for parts or pieces Vibrating. In conclusion, after having identified the main causes of the problem, it's noted that there is a link between the cause and the solution, detailing the development of the tools and the implementation to improve the availabilty of the mills. This increased significantly, going from a 67% before implementation to a 89% after it. In addition, an impressive increase was achieved in MTBF (Mean Time Between Failures), which rose from 13.20 to 51.46, this demonstrates a greater asset reliability. MTTR (Mean Time To Repair) is also reduced to 6.55 from 6.57, suggesting an improvement in how quickly faults are addressed, further more minimizing downtime.
