Da Falha à Confiabilidade: O impacto do Planejamento de Manutenção nos Processos Industriais

Abstract

This study presents the importance of strategic planning in industrial maintenance, highlighting its direct influence on the reliability, efficiency, and safety of production processes. The proper operation and planned maintenance of industrial equipment are essential to ensure production continuity and reduce operational costs. The research was developed through a qualitative and descriptive approach, based on a medium to large-sized steel plant located in the state of Minas Gerais, Brazil.The theoretical framework addresses the main concepts of corrective, preventive, predictive, and proactive maintenance, as well as management tools such as SWOT Analysis, Canvas Model, 5W2H, FMEA, and performance indicators (MTBF and MTTR). The practical application of the planning process was demonstrated through case studies in critical areas of the steel plant, such as rolling and reduction, emphasizing the benefits of preventive maintenance in strategic equipment, including rolling mill block motors and blast furnace blowers. The results showed that a structured maintenance planning significantly reduces unexpected failures, increases equipment availability, optimizes resource allocation, and enhances operational safety. It is concluded that strategic maintenance planning is an essential element for industrial sustainability and competitiveness, and it should be continuously improved and aligned with the organization’s operational goals.
