Abstract(s)
A produção Lean já provou ser uma filosofia de gestão eficaz para eliminar a perda de tempo nos processos de produção. Contudo, atualmente não basta apenas obter resultados económicos. Para o âmbito deste estudo ser realizado, foi desenvolvida uma pesquisa na plataforma Web of Science tendo como foco as Lean tools e Lean manufacturing, onde contém inúmeras publicações científicas feitas em instituições internacionais de renome. As publicações obtidas dessa pesquisa, foram submetidas a uma análise quantitativa. Com esta dissertação identificaram-se as ferramentas Lean mais utilizadas na indústria de processos e os benefícios associados. Fez-se a distribuição das ferramentas mais adotadas nos diferentes países e setores de atividade, bem como foram identificados os jornais científicos ou conferências internacionais que apresentaram mais trabalhos realizados na área da melhoria contínua através da adoção das ferramentas Lean. Após a análise quantitativa dos resultados, realizou-se uma análise qualitativa das publicações classificadas como sendo caso de estudo com a ferramenta Lean mais utilizada. Os resultados deste estudo demonstram que a ferramenta mais utilizada nas publicações analisadas foi o VSM- Value Stream Mapping com uma percentagem de 65%, o que corresponde a 62 em 95 publicações. De seguida surgem os 5S’s com uma percentagem de utilização de 48%, representando 46 em 95 publicações. Estes dados indicam que os autores dão bastante importância à análise do mapeamento do fluxo de valor nas organizações e que é quase sempre este o primeiro passo a dar para serem identificados os problemas ao longo da linha de produção. Dão também bastante importância à arrumação e limpeza dos postos de trabalho para que o desperdício seja reduzido e as operações sejam mais produtivas. Um outro objetivo deste estudo, passava por avaliar de alguma forma o grau de implementação geral da produção Lean nas organizações industriais. Nesse sentido, foi criada uma auditoria que abrange um vasto leque de ferramentas. Posteriormente, esta auditoria foi posta em prática numa empresa portuguesa do setor da metalomecânica, nomeadamente a Metalogalva - Irmãos Silvas, S.A.
Lean production has already proven to be an effective management philosophy to eliminate wasted time in production processes. However, currently it is not enough to just obtain economic results. For this study to be carried out, a survey was carried out on the platform which contains numerous scientific publications made in renowned international institutions, the Web of Science. The publications obtained from this research were subjected to a quantitative analysis. With this dissertation, the lean tools most used in the process industry and the associated benefits were identified. The most widely adopted tools were distributed in different countries and sectors of activity, as well as scientific journals or international conferences that presented more work in continuous improvement through the adoption of lean tools were identified. After the quantitative analysis of the results, a qualitative analysis of the publications classified as being a case study with the most used lean tool was carried out. The results of this study demonstrate that the most used tool in the analysed publications was the VSM with a percentage of 65%, which corresponds to 62 in 95 publications. Then 5S’s come up with a 48% utilization percentage, representing 46 in 95 publications. These data indicate that the authors place great importance on analysing the value flow mapping in organizations and that this is almost always the first step to be taken to identify problems along the production line. They also place a lot of emphasis on tidying and cleaning jobs so that waste is reduced, and operations are more productive. Another objective of this study was that it was possible to somehow assess the degree of general implementation of lean production in industrial organizations. That said, an audit was created that covers a wide range of tools. Subsequently, this audit was carried out in a Portuguese company in the metalworking sector, namely Metalogalva - Irmãos Silvas, S.A.
