Abstract(s)
Esta dissertação foi elaborada em ambiente industrial no Centro de Produção de Mangualde,
do Grupo PSA. Tem como objetivo estudar os postos de trabalho de uma linha de montagem
com o intuito de eliminar desperdícios e aumento do rendimento operacional. Com um
mercado cada vez mais competitivo, torna-se necessário que as empresas eliminem todas as
ações que em nada acrescentam valor ao produto de modo a aumentar o lucro. O ponto
abordado nesta tese foi o Standardized Work. Verificou-se que não existia um trabalho
standardizado e que antes de propor qualquer tipo de melhoria seria necessário fazer com
que os resultados fossem replicáveis para outros turnos. Foram analisados os postos de
trabalho para 2 turnos. Registaram-se tempos de ciclo para as diversidades produzidas mais
significativas, assim como as sequências/cronologias de operações. Com estes dados seria
possível afirmar qual o operador que tinha o melhor “Know How” do posto e se a sua maneira
de trabalhar devia ser aplicada aos outros turnos. Com os dados retirados também foi possível
atualizar os tempos definidos nas folhas standard, para que futuramente a equilibragem dos
postos de trabalho fosse feita de uma forma mais acertada. Os resultados obtidos e propostas
de melhoria apresentadas, permitiram que fosse possível diminuir o tempo de ciclo nos passos
de trabalho, principalmente no estrangulamento do setor analisado, fazendo com que o
rendimento operacional batesse o objetivo proposto de 97,4%.
This dissertation was prepared in an industrial environment at the Mangualde Production Center of the PSA Group. Its objective is to study the workstations of an assembly line in order to eliminate waste and increase operational efficiency. With an increasingly competitive market, it is necessary for companies to eliminate all actions that do not add value to the product in order to increase profit. The point discussed in this thesis was the Standardized Work. It was found that there was no standardized work and that before proposing any kind of improvement it would be necessary to make the results replicable for other shifts. The jobs were analyzed for 2 shifts. Cycle times were recorded for the most significant produced diversities, as well as sequences / chronologies of operations. With this data it would be possible to say which operator had the best "Know How" of the station and if its way of working had to be applied to the other shifts. With the data removed it was also possible to update the times defined in the standard sheets, so that in the future the balancing of jobs would be done in a more correct way. The results obtained and proposals for improvement showed that it was possible to reduce the cycle time in the work steps, mainly in the bottleneck of the analyzed sector, causing the operating efficiency to reach the proposed goal of 97.4%.
