Gestão da manutenção preventiva da infraestrutura predial: uma pesquisa-ação em uma empresa de minério de ferro

Abstract

The international business scenario is becoming increasingly competitive. Companies want to improve processes, which highlights the need to reduce waste and enhance results. Mining follows this context and has brought high competitiveness. The production of iron ore is obtained through drilling, blasting, loading, transport and infrastructure, the latter being fundamental, since infrastructure failures lead to inefficiency in production management. Therefore, improving building infrastructure production management processes in the Brazilian mining sector implies increasing the productivity of organizations. Thus, the issue of this work was reached: What results can the implementation of preventive maintenance in building infrastructure bring to the production management processes in iron ore processing? The general objective was to use production management tools to implement preventive maintenance in the area of building infrastructure in an iron ore processing company. To conduct the work, 3 complete cycles of research-action method were used as methodology. As a result of this dissertation, it was noticed that there is a lack of theoretical production within the theme, and the existing studies are recent. For the company under study, the project provided intelligent resource management, achievement of the company's strategic initiatives with effective management of indicators automatically and online, and greater employee and customer satisfaction, also notable is the Adherence to Call Answering Indicator, which surpassed the target set for 2020, reaching 93.51%. And although it was not raised as a project objective, the implementation also brought benefits related to the reduction of maintenance material costs, with a reduction of 60.40% in the first quarter of 2021.
