Proposta de melhorias em uma linha de montagem de uma indústria automotiva através do mapeamento do fluxo de valor

Abstract

To become more competitive, industries are using varied process optimization tools. When it comes to the automotive industry, the competitive edge is even stronger, with customers requiring products with availability, quality and low cost. In this context, the lean manufacturing tools are the best option for these industries to improve its processes. However, is still a challenge for the companies to organize and implement these tools. Therefore, to support strategic management of the improvements and to base decisions, the value stream mapping shows itself very effective. This paper aims to apply the value stream mapping on a bus assembly line in a heavy duty vehicles industry, located in Curitiba-PR. The methodology was used to identify improvement ideas, through current state mapping, and for a future state proposal, based on lean manufacturing tools. The results were the improvement of 1% in global aggregated value and reduction of 10 minutes on lead-time, which represents a gain of productivity of approximately R$ 330.000,00 per week. Also, with the adequation of the assembly line and the redistribution of operations, was obtained a reduction of approximately R$ 120.000,00 annually.
