Abstract(s)
Atualmente, as empresas de manufatura têm de lidar com a globalização, constantes mudanças tecnológicas e a evolução dos seus competidores diretos. Estes aspetos forçamnas a estar constantemente à procura de soluções que melhor se adaptem ao mercado onde se inserem, e permitam avaliar e melhorar os seus níveis de eficácia, eficiência e produtividade. O trabalho realizado incide na aplicação do indicador Overall Equipment Effectiveness (OEE) na melhoria de processos produtivos numa indústria de tintas e vernizes. O indicador OEE permitiu, por um lado, avaliar a eficácia operacional de processos produtivos e uma análise sistemática dos mesmos. Adicionalmente, foi utilizado para identificar e eliminar causas específicas e recorrentes que impactam negativamente o sistema produtivo, contribuindo, assim, para a sua melhoria. A implementação da medição do indicador OEE permitiu identificar Processos Bottleneck inerentes aos Processos Produtivos avaliados. Em acréscimo, foi desenvolvida uma ferramenta criada especificamente para a monitorização e avaliação dos dados obtidos, com o intuito de permitir o registo e cálculo deste indicador. A avaliação dos resultados iniciais permitiu identificar uma série de Propostas de Melhoria, com um impacto bastante positivo a nível de lucro potencial estimado de 490.450 €/ano. Finalmente, foi implementada no chão de fábrica, uma adaptação do conceito do comboio logístico que permitiu, em média, um aumento na eficácia operacional de 10%.
Nowadays, manufacturing companies must deal with globalization, constant technological changes and the evolution of their direct competitors. These aspects force the companies to be constantly searching for new solutions to better adapt to the market in which they operate and to evaluate and improve their levels of effectiveness, efficiency and productivity. The work carried out focused on the application of the Overall Equipment Effectiveness (OEE) indicator to improve production processes in a paint and varnish industry. The OEE indicator allowed us to evaluate the operational effectiveness of productive processes and perform a systematic analysis of them. Additionally, it was utilized to identify and eliminate specific and recurrent causes which impacted negatively the production system, thus contributing to its improvement. The implementation of the measurement of the OEE indicator made possible the identification of Bottleneck Processes inherent to the Productive Processes evaluated. Moreover, a tool was developed specifically for the monitoring and evaluation of the obtained data, with the purpose of registration and calculation of this indicator. The evaluation of the initial results allowed the identification of a series of Improvement Proposals, with a very positive impact and an estimated potential profit of 490.000€/annually. Finally, an adaptation of Milk Run concept was implemented on the factory floor, which allowed, on average, an increase of 10% in operating efficiency.
