Abstract(s)
Se por um lado a filosofia japonesa Lean Manufacturing, foca a sua atuação na
eliminação dos desperdícios, por outro, os americanos desenvolveram o Six Sigma que
almeja a redução na variabilidade dos processos. Ao observar as vantagens dos dois
métodos, alguns estudiosos e profissionais do setor industrial perceberam a
oportunidade de combiná-los para obter ganhos competitivos para as empresas,
especialmente tendo em vista um mercado cada vez mais disputado. A união destas
duas ferramentas é chamada de Lean Six Sigma.
O presente trabalho tem como objetivo implementar as ferramentas do Lean
Manufacturing numa organização do ramo automóvel, que possui um controlo dos
defeitos por milhão de oportunidades, ou seja, que tem no Six Sigma uma ferramenta
de garantia da qualidade dos seus produtos.
Neste sentido, o presente trabalho buscou aumentar o volume produtivo de uma linha
específica da empresa sob estudo tendo por base o uso das ferramentas Lean.
Para atingir tal objectivo foi feita uma revisão bibliográfica inicial, onde o autor expõe
as origens e desenvolvimento tanto do Lean Manufacturing quanto do Six Sigma, a
discussão sobre a abordagem híbrida dos dois, o Lean Six Sigma, e após isso apresenta
um estudo de caso onde o volume de produção serviu como parâmetro para medir a
eficácia das ações de melhoria implementadas.
Após a implementação das ferramentas Lean, foi verificou-se um aumento no volume
produtivo de 126,47%. Desta forma, este trabalho demonstrou a eficácia da utilização
de Ferramentas Lean para simplificação de um processo produtivo complexo,
aumentando o seu volume de produção. Para estudos futuros recomenda-se a
implementação de Ferramentas Lean mais complexas e a utilização de outros KPI (Key
Performance Indicators) para a avaliação dos resultados.
If, on the one hand, the Japanese Lean Manufacturing philosophy focuses on eliminating waste, on the other, the Americans developed Six Sigma, which aims to reduce the variability of processes. When observing the advantages of the two methods, some scholars and professionals in the industrial sector noticed the opportunity to combine them to obtain competitive gains for companies, especially in view of an increasingly competitive market. The union of these two tools is called Lean Six Sigma. This work aims to implement Lean Manufacturing tools in an organization in the automotive industry, which has a control of defects per million opportunities, that is, which has in Six Sigma a quality assurance tool for its products. In this sense, this work sought to increase the production volume of a specific line of the company under study based on the use of Lean tools. To achieve this goal, an initial literature review was carried out, where the author exposes the origins and development of both Lean Manufacturing and Six Sigma, the discussion on the hybrid approach of the two, Lean Six Sigma, and after that presents a case study where the production volume served as a parameter to measure the effectiveness of the implemented improvement actions. After the implementation of Lean tools, there was an increase in the production volume of 126.47%. Thus, this work demonstrated the effectiveness of using Lean Tools to simplify a complex production process, increasing its production volume. For future studies, is recommended the implementation of more complex Lean Tools and the use of other KPI (Key Performance Indicators) to evaluate the results.
