Abstract(s)
A presente dissertação foi realizada numa empresa do setor do mobiliário, em contexto
industrial no âmbito do Mestrado em Engenharia Eletrotécnica de Computadores
- Ramo de Sistemas e Planeamento Industrial, e teve como finalidade melhorar
o planeamento e controlo da produção, primeiramente com a implementação
de um Enterprise Resource Planning (ERP) na produção e seguidamente, o desenvolvimento
de uma ferramenta para apoiar o Planeamento e Controlo da Produção
(PCP) e potenciar o ERP.
Assim sendo, após uma análise da situação atual e perceção do funcionamento da
empresa, foram identificados alguns problemas e pontos de melhoria que negligenciam
os tempos de produção de cada artigo, nomeadamente: o facto de se realizar
um planeamento manual, que tem falhas devido à falta de informação e onde existem
semanas com excesso de carga produtiva; o facto de não haver dados concretos onde
se possa dar datas de entregas precisas (previsão incorreta dos prazos de entrega),
assim como orçamentação; mau acompanhamento/controlo da produção e a gestão
de stocks ineficiente.
Para solucionar os problemas encontrados, seria necessário, numa primeira fase,
implementar o ERP GPAC na produção, software que já existe para a gestão de
encomendas, de stocks, de Ordem de Fabrico (OF) e de Plano de Entregas (PE).
Essa fase partiria pela criação de artigos, componentes e árvores de produto, e após
isso a entrada no chão de fábrica para obtenção do tempo de produção de cada
artigo.
Posto isto, a fase seguinte seria o desenvolvimento de uma ferramenta excel que
realize o planeamento da produção, orçamentação e obtenção de datas de entregas
para as encomendas de forma mais automática e precisa, com base nos preços
tabelados de matéria-prima e subcontratados e em dados retirados do ERP, como
tempos de produção, consumos e nível de stock (artigos e matéria prima).
Inicialmente estas melhorias serão aplicados e aperfeiçoados na secção de produção,
sendo depois expandidos para a secção de montagem, acabamento e estofos,
consoante o avanço da implementação do ERP e na obtenção de dados.
This dissertation was carried out in a company in the furniture sector, within an industrial context, as part of the Master’s Degree in Computer Electrotechnical Engineering - Systems and Industrial Planning. Its purpose was to improve production planning and control, primarily through the implementation of an ERP system in production and then, the development of a tool to support production planning and control PCP and enhance the ERP system. After analyzing the current situation and understanding the company’s operations, several problems and areas for improvement were identified. These included neglecting the production times of each item, manual planning with flaws due to a lack of information, weeks with excessive production load, no concrete data for precise delivery dates (leading to incorrect delivery time predictions) and budgeting, poor control of production, and inefficient stock management. To address these issues, the first phase involved implementing the ERP GPAC system in production. This software is already in use, it manages orders, stocks, manufacturing orders OF, and delivery planning PE. This phase began with the creation of articles, components, and product trees, followed by implementing into the factory floor to obtain production times for each article. The next phase involved developing an Excel tool for more automatic and precise production planning, budgeting, and obtaining delivery dates for orders. This tool would be based on listed prices of raw materials and subcontractors and data from the ERP system, such as production times, consumption, and stock levels (articles and raw materials). Initially, these improvements will be applied and refined in the production section, and then expanded to the assembly, finishing, and upholstery sections, depending on the progress of ERP implementation and data collection.
