Abstract(s)
Fruto do aumento da competitividade a um nível global, as organizações sentem a necessidade cada vez maior de se destacarem focando-se assim na melhoria dos seus produtos e serviços, assim como na rapidez das entregas. Simultaneamente, a nível interno nas organizações, verifica-se um foco no aumento da eficiência da cadeia de valor, promovendo as atividades de acrescentam valor ao produto final e tentando simultaneamente eliminar ou reduzir aquelas que não agregam valor. Este trabalho tem como objetivo principal aferir quanto à possibilidade de aplicação das metodologias Kaizen-Lean em conjunto com a Indústria 4.0, de forma a promover o aumento da eficiência da manutenção. Este tema surge uma vez que o aumento da eficiência da manutenção leva a um maior OEE, o que possibilita à produção ter os seus equipamentos a laborar nas condições devidas durante uma maior percentagem de tempo, levando assim a uma maior eficiência produtiva e consequentemente da cadeia de valor. Foi aplicado um caso prático de implementação de interligação destas metodologias num motor problemático de uma organização, onde a manutenção era realizada de uma forma corretiva e o controlo do seu funcionamento era feito de forma esporádica no tempo. Desta forma, foi aplicado um sensor no equipamento, permitindo virtualmente observar continuamente a sua condição, permitindo assim promover a adoção da manutenção baseada na condição, eliminando assim desperdícios relacionados com a paragem da máquina devido ao incorreto funcionamento, aumentando assim a eficiência quer ao nível da manutenção quer ao nível da produção.
As a result of increasing competitiveness on a global level, organizations feel the growing need to distinguish by focusing on improving their products and services, as well their delivery times. At the same time, internally within organizations, there is a focus on increasing value chain efficiency by promoting value added activities to the product, while trying to eliminate or reduce those that do not add value. This work aims to assess the possibility of applying Kaizen-Lean methodologies in conjunction with Industry 4.0, in order to promote increased maintenance efficiency. This has arisen since increased maintenance efficiency leads to a higher OEE, which enables production to have its equipment working under the proper conditions for a longer percentage of time, thus leading to greater production efficiency and hence the supply chain value. A practical case of implementation of the connection of these methodologies was applied in a problematic engine of an organization, where the maintenance was performed on corrective mode and the control of its operation was done sporadically over time. In this way, a sensor was applied to the equipment, virtually allowing to observe constantly its condition, thus promoting the adoption of condition-based maintenance, thus eliminating waste related to machine shutdown due to malfunction, thus increasing efficiency at both maintenance and production.
