Análise da fiabilidade e melhoria do processo de fabrico: estudo de caso em uma fábrica de componentes para automóveis

Abstract

The today’s business driving, considering a globalized and highly competitive economy, requires changes in the mentality and attitudes of the industrial sector. The concept that the maintenance function is just to restore the original equipment conditions is overpast. In the current view, maintenance must be organized, and must avoid the occurrence of failure events, in order to reduce industrial costs and maximize the productivity of machines and equipment.Considering that the following study intends to promptly approach in a proactive way the improvement and optimization of the process of a specific production line through the strategic management of the maintenance activities. This work aims to study and analyze the reliability behavior of an industrial system, and use this information to manage maintenance activities in a more efficient way, aiming to contain failures and increase the operational availability of the machinery.After this study, it can be concluded that failure and reliability analysis were essential to assist the proper selection of the maintenance strategy that should be adopted and to prevent failures. It can also be concluded that, instead of seeking to eliminate all of the problems found in the production line, choosing to create a program of action for the most critical problems has led to a rapid decrease in the number of failures occurrences.
