Abstract
Hoy en día el mantenimiento no se limita a intervenir los equipos cuando éstos fallan, sino que forma parte de la estrategia dentro de la cadena de suministro, influyendo en aspectos como el nivel de servicios a producción, costos de producción, tiempo de respuestas a clientes, eficiencia de planta entre otros, aumentando así las ventajas competitivas, por lo que su análisis es de gran importancia.
En esta memoria se estudia el caso de la empresa Comercializadora Nutreco Chile limitada, Skretting Chile, la cual no dispone de un adecuado sistema de mantención, provocando detenciones correctivas, las cuales presentan costos de no producir, pérdidas de tiempo, falta de control, disminución de la vida útil de los equipos y no garantiza seguridad de los trabajos, lo que motivó el análisis y mejora de este sistema de mantenimiento por medio de la planificación del mantenimiento a través de la implementación de un Master Plan.
Para la elaboración del Master Plan, primero se evaluaron los aspectos fundamentales del mantenimiento preventivo bajo la situación actual del área de mantención, determinando así que hay requerimientos de información necesarios para mejorar el tipo de mantenimiento. Luego se diseñaron las etapas del Master Plan, estableciendo: la criticidad de los equipos, codificación física y virtual de equipos, estrategias de mantenimiento, se determinaron los servicios preventivos, frecuencias de ejecución, plan de mantenimiento, planes de trabajo, se equilibraron los planes de trabajo, se creó el calendario de mano de obra, se dió a conocer la plataforma y funcionamiento del software, los nuevos procedimientos y se implementaron indicadores de fiabilidad de sistemas a partir de criterios destacados en el Master Plan.
Con esta propuesta se disminuyó en 24,82 horas las detenciones mensuales por motivos eléctricos y mecánicos. Lo que llevó a disminuir las pérdidas en toneladas de producto terminado en un 64,64%, lo cual fue demostrado a través de un modelo matemático enfocado en los indicadores de fiabilidad de sistemas MTBF, Tiempo Medio Entre Falla, y MTTR, Tiempo Medio de Reparación, mejorando así la incidencia de Mantención en un 2,44% de la improductividad en la planta de Pargua.
Today maintenance is not limited to intervene when equipment or machinery fail, but is considered part of the strategy within the supply chain, influencing aspects such as the level of services to production, costs of production, response time to customers, plant efficiency among others, thus increasing the competitive advantages. In this report the case of a company limited Comercializadora Nutreco Chile, Skretting Chile, was studied; this company did not have a proper maintenance system , causing corrective arrests, increasing production costs, loss of time, lack of control, decreased the useful life of the equipment and safety not guaranteed jobs. This situation motivated the study, aimed to analyze and improve the current maintenance system through maintenance planning and the implementation of a Master Plan. To prepare the Master Plan, first the fundamentals of preventive maintenance were evaluated with the current situation, determining the information requirements necessary to improve maintenance. The phases of the Master Plan were then designed, including: criticality of equipment, physical and virtual equipment coding, maintenance strategies, preventive services, frequency of execution, maintenance plan, work plans, labor balance, and labor calendar. The platform and operating software were presented to the involved people, together with the new procedures and systems reliability. With this proposal the monthly arrests for electrical and mechanical reasons was decreased by 24.82 horas Leading to lower losses in tons of finished product in a 64.64%, which was demonstrated through a mathematical model focused on indicators of reliability of the systems such as MTBF (Mean Time Between Failure) and MTTR (Mean Time repair), decrease the incidence of Maintenance by 2,44% the unproductive in a plant Pargua.
