Abstract(s)
Num mercado tão competitivo como a indústria automóvel, torna-se cada vez mais importante para as organizações a implementação de uma cultura de melhoria contínua, transversal a todas as partes interessadas da organização. A melhoria contínua dos processos, o aumento da eficiência, e a eliminação dos desperdícios, leva a um aumento considerável da competitividade face ao mercado, não só económica, mas também tecnologicamente. A dissertação apresentada, retrata um trabalho realizado num estágio curricular, em contexto industrial, na área da melhoria contínua de processos produtivos. O estágio foi realizado numa empresa pertencente à indústria de componentes para automóvel, e decorreu entre os meses de Janeiro e Julho de 2018. Neste estágio, surgiu a oportunidade de integrar a equipa de melhoria contínua e QRQC (Quick Response to Quality Control) num novo projeto da empresa, designado por VS30. Neste projeto existem três linhas de produção, e uma zona de preparação que abastece a montagem final. O foco deste trabalho passou pela otimização de uma linha de produção, designada por AA20, tendo como objetivo principal aumentar a capacidade produtiva da linha, de forma a que esta seja capaz de cumprir com os pedidos do cliente. Assim, foram definidos como objetivos deste trabalho: aumentar a capacidade produtiva de 1200 peças/dia para 1800 peças/dia, e a redução do tempo médio de setup em pelo menos 20%, de forma a possibilitar o aumento da disponibilidade da linha. As metodologias utilizadas baseiam-se em várias técnicas e metodologias lean e de melhoria contínua, tais como balanceamento de linhas, SMED, standard work, gestão visual e 5 S. O trabalho desenvolvido permitiu aumentar em 37% a capacidade produtiva da linha, e uma redução de 34% no tempo médio de setup. Através de todas as melhorias implementadas, e do trabalho desenvolvido por toda a equipa envolvida no projeto, foi possível aumentar o OEE da linha de 53% para 74%.
In a market as competitive as the automotive industry, it becomes increasingly important for the organizations to adopt a culture of continuous improvement, which should cross-over all stakeholders in the organization. The continuous improvement of the processes, the increase in efficiency, and the elimination of waste, leads to a considerable increase in market competitiveness, not only economically, but also technologically. The dissertation presented, portrays the work carried out in an internship, in industrial context, in the field of continuous improvement of the productive processes. The internship was carried out in a company belonging to the automotive component industry and took place between January and July of 2018. There was the opportunity to integrate the continuous improvement and QRQC (Quick Response to Quality Control) team in a new project of the company, designated by VS30. In this project there are three production lines, and a preparation area that supplies the final assembly. The focus of this work was the optimization of a production line, designated by AA20, with the main goal being the increase of the productive capacity of the line, so that it can comply with the customer's requests. Thus, they were defined as goals of this project: to increase the productive capacity to 1800 parts/day, and the reduction of the average setup by at least 20%, to increase the availability of the production line. The methodologies used are based on several continuous improvement and lean techniques, such as line balancing, SMED, standard work, visual management and 5 S. The work developed allowed an increase of 37% of the production line capacity, and a reduction of 34% in the average setup time. Through all the improvements implemented, and the work developed by the entire team involved in the project, it was possible to increase the OEE of the production line from 53% to 74%
