Sistema de gestión de mantenimiento basado en confiabilidad. Caso de estudio: Planta de tratamiento de agua empresa DIALILIFE

A maintenance management system based on operational reliability is based on the process of improving technical maintenance indicators, in which a management model is applied in stages, developed and executed according to the current conditions of the plant, in order to optimize the planning, scheduling and execution of preventive maintenance processes. The use of a methodology that allows evaluating the inherent variables and the operational characteristics of the system, allows to increase the performance of the maintenance unit, by carrying out a comprehensive treatment of asset management and organizational management for a real treatment of the maintenance plan. This evaluation process was carried out through an analysis with RAM methodology, which allows establishing the behavior of maintainability, reliability and availability as technical management indicators based on the volumetric production requirements of treated water for hospitals such as DIALILIFE. SA that, by processing the data obtained from the systematic evaluations, managed to establish a theoretical model focused on continuous improvement, and likewise, establish the incidence of the application of the management, with the improvements in the average times between failures "TPEF", the average times to repair “TPPR” and reduce the number of scheduled or unscheduled plant shutdowns, as a fundamental contribution to increasing the reliability of the water treatment plant equipment. Keywords: Operational reliability, maintenance management, maintainability, availability.Un sistema de gestión de mantenimiento basado en la confiabilidad operativa se fundamenta en el proceso de mejora de los indicadores de mantenimiento técnico, en el cual, se aplica un modelo de gestión por etapas, desarrollado y ejecutado según las condiciones actuales de la planta, con el fin de optimizar los procesos de planificación, programación y ejecución del mantenimiento a nivel preventivo. El empleo de una metodología que permita evaluar las variables inherentes y las características operacionales del sistema permite aumentar el rendimiento de la unidad de mantenimiento, al realizar un tratamiento integral de la gestión de activos y gestión organizacional para un real tratamiento del plan de mantenimiento. Este proceso de evaluación se lo realizo mediante un análisis con metodología RAM, la cual permite establecer el comportamiento la mantenibilidad, confiabilidad y disponibilidad como indicadores técnicos de gestión en función de los requerimientos de producción volumétrico de agua tratada para los centros hospitalarios como la empresa DIALILIFE S. A. que, mediante el procesamiento de los datos obtenidos de las evaluaciones sistemáticas, logró establecer un modelo teórico enfocada la mejora continua, y así mismo, establecer la incidencia de la aplicación de la gestión, con las mejoras los tiempos promedios entre fallas “TPEF”, los tiempos promedios para reparar “TPPR” y disminuir el número paradas programadas o no programadas de planta, como aporte fundamental al aumento de la confiabilidad de los equipos de la planta de tratamiento de agua. Palabras clave: Confiabilidad operativa, gestión de mantenimiento, mantenibilidad, disponibilidad.
