Abstract(s)
Ao longo do tempo, o constante desenvolvimento da humanidade apresenta uma panóplia de
desafios sem precedentes. O crescente aumento da população mundial, aliado aos padrões de
vida cada vez mais elevados, tem forçosamente implicado uma escassez de recursos e
contribuído para as alterações climáticas que vivemos nos dias de hoje. Como resposta a este
problema, nas últimas décadas, surgiu um novo conceito: a sustentabilidade. Este assenta nos
pilares económico, social e ambiental, almejando a consciencialização generalizada da
sociedade para o enorme desafio apresentado e para a aplicação de medidas mitigadoras do
problema. Adicionalmente, é importante realçar que a filosofia lean desempenha um papel
preponderante nos processos das organizações, visando, essencialmente, a maximização do
valor final entregue ao cliente e a redução dos seus desperdícios. Assim, a presente dissertação
de mestrado, pretende dar resposta à questão de investigação: De que forma a implementação
da filosofia lean numa empresa produtora de antenas, pode contribuir para a promoção e
desenvolvimento da sustentabilidade organizacional? Para o seu desenvolvimento, utilizou-se
como metodologia de investigação a metodologia Action-Research, caraterizada por apresentar
respostas a problemas reais, num contexto industrial, na empresa Continental Advanced
Antenna. Todo o estudo realizado incidiu sobre uma das linhas de produção de antenas. O
desenrolar desta investigação passa pela implementação de ferramentas da qualidade e
estratégias que permitam um aumento considerável da sustentabilidade da organização.
Diversas ferramentas lean foram utilizadas tais como o SMED, o A3, o 5S, o Standard Work,
entre outras, permitindo, assim, o alcance de resultados positivos para a organização
aumentando a capacidade produtiva e minimizando o seu impacto ambiental. A presente
abordagem permitiu um aumento da capacidade produtiva aproximado de 10%.
Adicionalmente, reduziu o impacto ambiental da linha de produção através da redução
expressiva de 35% do seu scrap e da redução de 10% no consumo de energia elétrica.
Finalmente, avanços significativos foram realizados no âmbito do pilar social, permitido o
alcance da participação dos colaboradores nos processos de decisão em 67% das vezes. Os
resultados de inquéritos aos colaboradores, permitiram analisar um impacto positivo da
implementação das ferramentas lean nas condições de segurança com cerca de 89% dos
colaboradores a concordar e relativamente ao aumento das condições de trabalho, obteve-se
uma aprovação de 100%. Por conseguinte, estabeleceu-se uma importante ponte os conceitos,
sustentabilidade e filosofia lean, assinalando o importante impacto do lean na sustentabilidade.
Over time, humanity's constant development presents an unprecedented range of challenges. The growing increase in the world's population, combined with increasingly higher living standards, has necessarily resulted in a scarcity of resources, and contributed to the climate changes we are experiencing today. In response to this problem, in recent decades, a new concept has emerged: sustainability. This is based on the economic, social, and environmental pillars, which aims to raise widespread awareness among society of the enormous challenge presented and the application of measures to mitigate the problem. Additionally, it is important to highlight that the lean philosophy plays a preponderant role in organizations' processes, aiming to maximize the final value delivered to the customer and reduce waste. Thus, this master's thesis aims to answer the research question: How can the implementation of lean philosophy in an antenna producing company contribute to the promotion and development of organizational sustainability? For its development, the Action-Research methodology was used as a research methodology, characterized by presenting answers to real problems, in an industrial context, at the company Continental Advanced Antenna. The entire study carried out focused on one of the antenna production lines. The development of this research involves the implementation of measures that allow for a reduction in downtime and, consequently, the maximization of line availability. Several lean tools were used such as SMED, A3, 5S, Standard Work, among others, thus allowing the organization to achieve positive results for the organization by increasing production capacity and minimizing its environmental impact. This approach allowed an increase in production capacity of approximately 10%. In addition, it has reduced the environmental impact of the production line through a significant 35% reduction in scrap and a 10% reduction in electricity consumption. Finally, significant advances have been made in the social pillar, allowing employees to participate in decision-making processes 67% of the time. The results of employee surveys made it possible to analyse the positive impact of the implementation of lean tools on safety conditions, with around 89% of employees agreeing, and in relation to the increase in working conditions, 100% approval was obtained. Therefore, an important bridge between these two concepts, sustainability, and lean philosophy, was established, marking the important impact of lean on sustainability.
