Abstract(s)
A presente dissertação enquadra-se no mestrado em engenharia mecânica, ramo de gestão industrial, e foi realizada em contexto industrial na ENERGIE EST, Lda.
O principal objetivo desta dissertação de mestrado, foi identificar melhorias que pudessem traduzir-se num aumento de eficiência de uma das linhas de produção da empresa, com recurso ao estudo de métodos e tempos.
Desta forma, fez-se uma revisão bibliográfica acerca dos conceitos estudo dos métodos, estudo dos tempos e lean manufacturing, por estar ligado ao método. Devido à não existência de documentação acerca de tempos das operações, foi feita, inicialmente, uma recolha de dados acerca de tempos e das operações de dois produtos, escolhidos em função da dificuldade do processo e das vendas. Após a recolha de dados foi feita uma análise crítica para identificar oportunidades de melhoria e implementadas algumas melhorias. Por fim, foi feito o estudo dos tempos para determinar o tempo padrão e propor melhorias com base nesses tempos.
Durante o estágio, foi possível acompanhar a simplificação ou eliminação de algumas operações que fizeram com que fosse reduzido algum trabalho. No mesmo sentido, foram realizadas propostas de melhoria que se focam em eliminar operações, principalmente nas atividades pré-produtivas. Assim sendo, é esperado reduzir o tempo e preparação dos capacetes para o MB 300EX em 26,6%, 35,5% na preparação dos capacetes para o MB 100esm e 52,5% na preparação das bases para o MB 100esm.
Num ponto de vista de organização do trabalho, foi proposta a padronização do trabalho, a organização dos postos de trabalho com a ajuda do 5S, a adoção do sistema one-piece-flow e o balanceamento da linha. Com a implementação das melhorias propostas para a organização do trabalho, é esperado, essencialmente, reduzir o trabalho em processamento, eliminar movimentações desnecessárias para procurar e transportar ferramenta/matéria prima e reduzir transportes durante o processo produtivo.
The present dissertation fits in the master degree of mechanical engineering at the specialization of industrial management, and it was developed in industrial context at ENERGIE EST, Lda. The main goal of this master dissertation was identifying improvements, that can lead to an efficiency increase of one of the production lines of the company, with methods and time study as resources. Thus, was made a literature review about the concepts method study, time study and lean manufacturing. This last one was made because de direct relation with the methods. Due to the non-existence of documentation about the operations times, initially, was made a data gathering about the times and the operations, of two products that were picked in function of the process difficulty and the sells quantities. After the data gathering it was made a critical analysis to identify improvement opportunities and implemented some improvements. Lastly, it was done a time study to define the standard time and to propose improvements with that times. During the internship, it was possible to go along with the simplification or the full elimination of some operations that reduce the work. With the same proposition, it was made improvement proposals that focus in eliminate operations, mainly in preproductive activities. Therefore, it’s expected to reduce the preparation time of helmets for the MB 300EX by 26,6%, 35,5% at helmets preparation for the MB 100esm and 52,5% at basis preparation for the MB 100esm. In the point of view of work organization, it was proposed standardize the work, organize the work stations applying 5S, adopt the system one-piece-flow and work balancing. With the implementation of the improvements proposals for the work organization, it is expected, essentially, reduce the work in process, eliminate the unnecessary movements for searching and transport tools/feedstock and reduce the transportation during the productive process.
