Abstract(s)
Atualmente, o background de um mercado competitivo ilustra a procura contínua por uma maior qualidade de produto, que é essencial para qualquer empresa. Para vingar num mercado assim, existem cada vez mais esforços no sentido de satisfazer as necessidades dos clientes assim como manter a rentabilidade e tentar reduzir os custos de operações. Face a estas necessidades, cada vez mais as empresas implementam metodologias definidas como Lean Manufacturing, tendo como base uma filosofia de gestão focalizada em identificar e eliminar desperdícios (atividades que não agregam valor) através da melhoria contínua, que têm apresentado excelentes resultados.
O projeto abordado neste relatório tem como principal objetivo a elaboração de instruções de trabalho, de limpeza, especificações técnicas para as várias etapas do processo produtivo, planeamento e implementação de soluções para melhorias do processo, com base em ferramentas Lean Manufacturing e Kaizen.
Foi ainda realizado para implementação na empresa acolhedora um breve estudo do estado da arte da tecnologia solar fotovoltaica, seguido do seu funcionamento, do dimensionamento e do estudo da viabilidade económica de um sistema fotovoltaico para rodução de energia.
Com a finalidade de melhorar resultados, foram realizadas 26 instruções de trabalho, 13 instruções de limpeza, 4 instruções de qualidade e 9 especificações técnicas, com o intuito de uniformização dos procedimentos em cada operação e também como auxilio para novos membros integrantes na equipa.
De modo a reduzir a faturação energética da empresa, foi efetuado um dimensionamento de uma instalação fotovoltaica para produção de energia. Com a sua elaboração verificou-se que não se reuniam as condições para que a empresa conseguisse ser 100% autossuficiente, uma vez que não possui uma área disponível para aplicação do sistema que suportasse os consumos atuais.
Portanto foi realizado um dimensionamento com a finalidade de reduzir a faturação energética. A instalação é então composta por 505 painéis policristalinos compostos por 60 élulas, com uma potência de 136,4 kWp. O investimento para a instalação tem como valor 125 000 €, estimando-se um período de retorno ao fim de dez anos.
Nowadays, the background of a competitive marketplace demonstrates the ongoing demand for greater product quality, which is essential for any business. To avenge this market, more and more efforts are made to meet customer needs, as well as maintain profitability and reducing operations costs. Faced with these needs, companies are increasingly implementing methodologies defined as Lean Manufacturing, based on a management philosophy focused on identifying and eliminating waste (activities that do not add value) through continuous improvement, which have presented excellent results. The main objective of this project is the elaboration of work instructions, cleaning instructions, technical specifications for the various stages of the production process, planning and implementation of solutions for improvements, using Kaizen and Lean Manufacturing tool. A brief study of the solar photovoltaic technology state-of-the-art was also carried out for the company, followed by its operation, the design and the study of the economic viability of a hotovoltaic system for energy production. In order to improve results, 26 work instructions, 13 cleaning instructions, 4 quality instructions and 9 technical specifications were carried out with the aim of standardizing the procedures in each operation and also as an aid to new members in the team. In order to reduce the energy billing of the company, was designed a photovoltaic system or energy production. With its elaboration it was verified that the conditions were not met so that the company could be 100% self-sufficient, since the available area for application of the system is not enough to support the current consumption. Therefore a sizing was carried out in order to reduce energy billing. The resulting facility is composed of 505 polycrystalline panels composed of 60 cells, with a power of 136,4 kWp. The investment for the installation has a value of € 125 000, with an estimated return period of tem years.
