APLICAÇÃO PRÁTICA DA ANÁLISE DO CUSTO DE CICLO DE VIDA DE ATIVOS EM SETOR DE MANUTENÇÃO DE UMA MINERADORA

Abstract

Among the many challenges that companies face today, that of staying competitive is the biggest one. They need the ability to manage the costs of their assets. Decision making regarding the replacement of equipment still has a technical bias and, in many cases, occurs late, without a long-term vision, as it does not consider the total costs of its assets. In this sense, this work intends to explore Asset Management, which is still a subject little discussed in the academic environment. As a problem, we ask how the Life Cycle Cost Analysis method of a fleet of assets of a mining company can define the ideal moment for their replacement? The scientific methodology used in the present study is characterized by quantitative, exploratory and field research. And the method of application of the study consisted of the application of the steps of the analysis of the cost of the life cycle supported by the methods of economic analysis of the ERV and CAUE. Despite the lack of a practical structure, difficulty in acquiring reliable historical data and more reliable operational life projections, it was possible to succeed by providing a broad understanding of the assets and helping the company to understand that if an asset management system was already implemented, with monitoring of the life cycle of assets, replacement and disposal actions would be carried out at the correct time, bringing a gain of more than 40% in corrective costs, in addition to offering more safety for people and less environmental impacts due to incidents caused by failures . In this way, it was possible to compare maintenance strategies and alternatives to support the management decisions of this asset with a long-term view, defining restrictive criteria, guidelines and requirements of common technical processes to manage the assets and deal with the inherent risks of the activities and processes.
