Abstract
Clariant Ltda. es una empresa multinacional dedicada a la elaboración de materias primas químicas específicas para las grandes industrias del mundo. La empresa busca mejorar y estandarizar la calidad de sus procesos productivos y de gestión de la unidad de negocios Masterbatches de Clariant Chile, la cual produce pellets de distintos tipos de polímeros para que otras empresas logren fabricar sus productos finales. Ésta presenta gran cantidad de detenciones no programadas, por lo cual requiere un análisis y mejora de la gestión del mantenimiento en sus equipos.Para esto, se hace una introducción de las estrategias de mantenimiento existentes, conceptos de confiabilidad, disponibilidad, estudio de las principales técnicas de jerarquización de activos y herramientas analíticas para optimizar la gestión del mantenimiento. Se estudian en detalle las técnicas de jerarquización de activos para conocer las alternativas de determinación de los equipos críticos. Se analiza el proceso productivo de la planta, con el fin de conocer el funcionamiento e importancia de cada máquina.Se recopilan datos históricos de las fallas de cada equipo y se investigan los requerimientos corporativos de la compañía para selección de equipos críticos. Ya conocido el contexto operacional, se analizan las ventajas y desventajas de cada método de selección. Se establece que el método de mejor aplicación es el analytic hierarchy process (AHP), con lo cual se identifican los equipos críticos del proceso. Los resultados son comparados con los obtenidos mediante la técnica Jack Knife, lo cual muestra similitud de resultados.Finalmente se desarrollan planes de mantenimiento a cada equipo crítico, integrando la herramienta de análisis FMEA y las restricciones de recursos técnicos y humanos del departamento, los cuales incorporan criterios de mantenibilidad en su diseño.
Clariant Ltda. it´s a multinational company dedicated to the elaborate a chemical raw for the major industries of the world. The company seeks to improve and standardize the quality of their production processes and management of business of Clariant Masterbatches Chile, which produces pellets of different types of polymers so that other companies can manufacture the final products. This company presents a big number of detentions not scheduled, so it requires an analysis and improvement of the management of the maintenance on their equipment. For this intervention is necessary an introduction of the existing maintenance strategies, concepts of reliability, availability, study of the main techniques of hierarchy of assets and analytical tools is done to optimize the management of the maintenance. Assets ranking techniques are discussed in detail to learn about alternatives to determination of critical equipment. The production process of the plant is analyzed in order to know the functioning and importance of each machine. Historical data of each equipment failures are collected and investigated the corporate requirements of the company for selection of critical equipment. Already known the operational context, the advantages and disadvantages of each method of selection are analyzed. Establishes that the best application method is the analytic hierarchy process (AHP), which identified critical process equipment. The results are compared with those obtained using the Jack Knife technique, which shows similarity of results. Finally develop maintenance plans at each critical equipment, integrating analysis FMEA tool and the restrictions of technical and human resources of the department, which incorporate judgement for maintainability in your design.
