Análise de intervalos ótimos de manutenção preventiva da tesoura de pontas da cadeira de laminação de bobinas da Arcelormittal Tubarão

Abstract

Given the need for companies to increasingly embrace continuous improvement as a premise for their survival in the marketplace, asset management tools are consolidating their space within the corporate world. An important phase of the asset's life cycle is its maintenance, and the more assertive the decisions in this period, the greater competitiveness and results will be achieved. This work aims to present a methodology for defining optimal intervals for preventive maintenance, based on probabilistic models of reliability and maintainability and the interaction between the costs of corrective and preventive activities, as well as presenting their results applied to the ArcelorMittal Tubarão Hot Strip Mill.
