Resumo

Nos últimos anos, é notória a evolução das empresas brasileiras no que tange a busca por otimizar os seus resultados industriais. Estudos do Lean Institute Brasil (2012) indicam que as indústrias do Brasil são, em média, as que necessitam o maior número de horas extras para o cumprimento das operações de manufatura, fato diretamente vinculado à elevada quantidade de estoques entre processos, desperdícios na movimentação e armazenagem de materiais. Logo, o artigo objetiva desenvolver uma metodologia que viabilize o estudo da maneira na qual funciona a cadeia de suprimentos interna de empresas fabricantes de ônibus do Brasil, em específico para os seus componentes comprados, com base no método denominado Making Materials Flow, para a correção das situações elencadas, havendo, ao final, uma redução em 40% do total de itens em falta para a linha de montagem e colaborando para o aumento de 37% na produção por dia.

Abstract

Recently, Brazilian companies have searched for ways to optimize the results of industrial processes. Studies by the Lean Institute Brasil (2012) indicate that the industries of Brazil, on average, require the most overtime for compliance with manufacturing operations. This is directly linked to the high amount of stocks between processes, waste handling and the storage of materials. Thus, this article aims to study the way in which the internal supply chain operates in a bus manufacturing company in Brazil. Specifically, purchased components are studied to find ways to obtain industrial gains, and a methodology called Making Materials Flow is used to correction the problems that are identified. In the end, missing items in the Assembly Line were reduced by 40%, the number of buses produced per day increased by approximately 37%.
