Análise comparativa do custo do ciclo de vida de rodas ferroviárias do fabricante A e do fabricante B em vagões de minério

Abstract

Faced with the scenario where the industries are where the focus on cost reduction becomes a matter of survival in the market. This research presents a life cycle cost analysis between two types of wheel manufacturers (Manufacturer A and Manufacturer B). In the paper we present an overview on wheels, LCC, distribution of probabilities for analysis of the average life of the wheels. For the analysis of the average life of the wheels, the WEIBULL ++ software degradation analysis tool was used and for the life cycle cost analysis a simple analysis was performed comparing the relation between the wheel purchase cost and average life between the two types of manufacturer. Another life cycle cost assessment was performed using the acquisition costs and costs between the machining times of each wheel type. Manufacturer A had an average life of over 38,89% over manufacturer B.
