Resumo(s)
Na atualidade, com a crescente competitividade e concorrência, existe uma pressão
constante para que as empresas se adaptem e evoluam. Os requisitos dos clientes são cada
vez mais exigentes e novos paradigmas socioeconómicos têm contribuído para a procura
pela melhoria contínua nas organizações. No setor industrial, a filosofia
Lean, a partir da
identificação e eliminação dos desperdícios, assume um papel preponderante como meio
para atingir o objetivo de aumentar a produtividade e a eficiência dos processos.
Neste contexto, a principal finalidade da presente dissertação é conceber um modelo
que permita identificar a área fabril onde se verificam mais desperdícios (setor crítico). Para
além disso, pretende-se identificar e priorizar problemas, promovendo a sua eliminação
através da implementação do
Lean. Este modelo integra diferentes tipos de ferramentas e
considera uma nova abordagem à Casa da Qualidade. Contempla seis etapas, em que o
feedback dos colaboradores da organização e o mapeamento do estado atual, através do
Value Stream Mapping (VSM), permitem a identificação do setor crítico. Posteriormente,
realiza-se um levantamento exaustivo de problemas, seguido pela sua priorização e
identificação das causas-raiz. Através destas, as ferramentas
Lean mais adequadas são
implementadas, contribuindo para a disseminação e sustentação de uma cultura de melhoria
contínua na organização.
O estudo inerente à aplicação do modelo insere-se numa fábrica metalúrgica da
indústria automóvel, que se dedica ao fabrico e venda de molas de suspensão. É aplicado
com o intuito de reduzir os desperdícios e efetuar melhorias. Este trabalho enfatiza a
relevância da priorização de setores e problemas para ultrapassar as constantes adversidades
decorrentes da limitação de recursos. Os resultados obtidos, embora careçam de mais tempo
para validação e um acompanhamento contínuo do processo, apontam para uma diminuição
dos desperdícios e aumento da produtividade.
Nowadays, with increasing competitiveness and competition, there is constant pressure for companies to adapt and evolve. Customer requirements are increasingly demanding, and new socioeconomic paradigms have contributed to the pursuit of continuous improvement in the organizations. In the industrial sector, the Lean philosophy, through the identification and elimination of waste, have been emerging to achieve the goal of enhancing productivity and process efficiency. In this context, the main purpose of this master thesis is to design a new model that enables the identification of the manufacturing area where the most waste occurs (critical sector). Furthermore, it aims to identify and prioritize problems, facilitating their elimination through the implementation of Lean. This model integrates different tools and considers a new approach to the House of Quality. It considers six stages, in which the feedback from the organization and mapping the current state with the Value Stream Mapping (VSM) enables the identification of the critical sector. Subsequently, an exhaustive survey of issues is conducted, followed by its prioritization and identification of root causes. Through these, the most suitable Lean tools are implemented, contributing to the dissemination and sustainability of a culture of continuous improvement within the organization. The study inherent to the application of the model takes place in a metallurgical automotive industry plant, which produces and sells suspension springs. It is applied with the intention of reducing waste and carrying out improvements. This work emphasizes the importance of prioritizing sectors and problems to overcome the constant challenges resulting from limited resources. The results obtained, although require more time to verify the results and the continuous monitoring of the process, indicate a decrease in waste and an increase in productivity.
