Abstract(s)
As pequenas e médias empresas no setor da indústria transformativa representam uma quota de 5,6% do número total de empresas em Portugal. É neste grupo que se insere a FUTE SA – Fábrica de Utilidade e Tubo S.A., que como as restantes empresas deste conjunto tem de ter uma orientação para o mercado, na medida em que este último define as suas exigências e a empresa tem de dar resposta eficazmente e com rapidez. Para tal é necessária uma elevada flexibilidade do produto e da produção, o que levanta vários problemas na sua implementação e aplicação.
Este projeto tem como objetivo analisar as dificuldades práticas no fabrico de uma elevada gama de produtos diferentes e combatê-las, tornando o processo mais lean e sistemático. Os objetivos passam por uma melhoria do aproveitamento do espaço produtivo na secção da montagem da empresa, diminuição dos tempos improdutivos com uma sistematização da informação produtiva chave.
Neste trabalho foi utilizada a metodologia DMAIC para a melhoria dos aspetos mencionados. Para o primeiro objetivo foi definido o estado inicial e calculada a ocupação atual assim como uma análise da contribuição para o sucesso da empresa de cada linha de montagem. Seguidamente, através da metodologia PDCA, foi desenvolvido um plano de melhoria que passava pelo redesenho do layout fabril da secção. No segundo objetivo foi seguida a mesma metodologia de melhoria, concluindo-se que a empresa era débil na sua componente técnica. A melhoria passou pela definição e caracterização das linhas e do processo de montagem assim como ma sistematização da especificação de cada cliente.
Os resultados alcançados traduziram-se num aumento de produção em 18% através da diminuição do tempo improdutivo e um aumento significativo da ocupação das linhas de montagem.
Small and medium-sized enterprises in the manufacturing sector account for 5.6% of the total number of companies in Portugal. It is in this group that FUTE SA is included, which like the other companies in this group has to have a orientation towards the arket, since the latter defines its requirements and the company has to respond effectively and quickly. This requires high product and production flexibility, which causes a number of problems in its implementation and application. This project aims to analyze the practical difficulties in manufacturing a wide range of different products and to combat them, making the process more lean and systematic. The objectives are to improve the utilization of productive space in the assembly ection of the company, reduce unproductive times and systematize key production information. In this work the DMAIC methodology was used to improve the mentioned aspects. For the first objective it was defined the initial state and calculated the current occupation as well as an analysis of the contribution to the success of the company of each assembly line. Then, through the PDCA methodology, an improvement plan was developed that went through the redesign of the manufacturing layout of the section. In the second objective, the same improvement methodology was followed, concluding that the company was weak in its technical component. The improvement went through the definition and characterization of the lines and the assembly process as well as a systematization of the specification of each customer. The results achieved resulted in a 18% increase in production through the reduction of unproductive time and a significant increase in occupation of the assembly lines.
