Sistema de manutenção e gerenciamento de frotas: um modelo para empresas mineradoras

Abstract

Effectively managing the resources and flow of information in a productive system is essential when competitiveness is sought, that is, quality products at the lowest cost, thus favoring permanence in the market. The variety and quantity of products are increasing in order to please consumers, but this condition also influences the growth of the equipment needed to reach production. In this universe, is the Maintenance System with responsibility to maintain and repair items that participate in the production process. In companies that use vehicles as means of production, the challenges faced by Maintenance are even more potent, due to the operational characteristics and external influences, such as: climatic condition, soil and relief, operator, etc. Of the productive sectors that make use of mobile equipment, we will approach the one of Mining. Therefore, the objective of this work is to structure a Maintenance System model and to elaborate a Management Model for mining fleets based on TPM (Total Productive Maintenance) and RCM (Reliability Centered Maintenance) management methodologies. For this, concepts of industrial maintenance along with the maintenance of urban transportation fleets contained in scientific articles, dissertations and bibliographic materials were adapted. For the elaboration of the study, it was necessary to experience in practice the day to day of a Maintenance System, thus, a field survey was carried out with the purpose of determining the needs and challenges faced by the System. It is also the goal of the study to approach Maintenance as a strategic function and to present how, through the developed Model, indicators are produced that are auxiliary to the decision-making process, which aims to lead the organization to a more competitive position.
