Avaliação nos indicadores de manutenção após reestruturação organizacional nas equipes de manutenção e de produção em uma indústria no Paraná

Abstract

With a current and global competitive market, companies must strive for excellence in their processes and products. The concepts of WCM (World Class Manufacturing) and TPM (Total Productive Maintenance) are currently used by multinationals for the purpose of continuous improvement. Topics were addressed in this work of both concepts as forms of organizational structures and tools of measurement and control. In this case study, a change in organizational structure in the production and maintenance teams was correlated with the short-term impacts generated in the maintenance indicators. The company under study made the change in its structure from the matrix form to the functional or departmental structure. Such changes occurred after profile studies of each post and objectives of each line. The maintenance indicators (reliability) compared before and after the change were: MTTR (mean time to repair) and MTBF (mean time between failures). The initial objectives of a 10% reduction in MTTR and a 20% increase in MTBF were not achieved in the short term. External factors, such as new products and end-of-line projects, and internal factors, such as inexperience of labor and poor management of indicators, contributed to the undesirable results with a 3% increase in MTTR and a 167% reduction in MTBF.
