Abstract(s)
Diante da necessidade crescente em se obter produtos e serviços cada vez mais aprimorados, processos produtivos otimizados e ativos disponíveis, as empresas têm procurado implementar, melhorias significativas que permitam uma entrega final mais competitiva. É essencial para as Organizações terem os seus ativos disponíveis e funcionais em tempo útil para garantir estes resultados, o que só se obtém através do aumento da disponibilidade operacional. A disponibilidade operacional de um ativo é afetada pelos aspetos inerentes a aplicação, manutenção e uso deste, e pelas particularidades da sua conceção e fabrico, sendo largamente condicionada por fatores com interferência direta como a operação e planeamento de produção, as ações de manutenção, a gestão dos recursos, o tipo de manutenção aplicada, pelo que a Manutenção desempenha um papel fundamental no estudo desta e no processo produtivo do ativo. É através da Manutenção que é possível melhorar as condições de funcionamento dos ativos, e acrescentar valor aos seus serviços e produtos. Desta forma, é foco desta presente dissertação, quantificar a influência dos fatores considerados na disponibilidade operacional de uma linha de produção da indústria cimenteira, através da aplicação de metodologias e ferramentas de análise de falha, especificamente a análise de Root Cause Analysis, que permitam aumentar a disponibilidade operacional dos ativos físicos na Indústria Cimenteira através da identificação dos modos de falha recorrentes para os ativos físicos em análise. Através desta análise, será proposto um plano de manutenção que previna os modos de falha considerados recorrentes e mitigue aqueles que não podem ser evitados na sua totalidade. A implementação desta metodologia fornecerá à manutenção informação essencial para a otimização da sua gestão e para a melhoria da qualidade das suas atividades.
Abstract Faced with the growing need to obtain increasingly refined products and services, optimized production processes, and available assets, companies have been seeking to implement significant improvements in their production chain that enable a more competitive final delivery. It is essential for organizations to have their assets available and functional in a timely manner to achieve these results, which can only be obtained by increasing operational availability. The operational availability of an asset is affected by aspects inherent to its application, maintenance, and use, as well as by the particularities of its design and manufacturing, and is largely influenced by factors such as operation and production planning, maintenance actions, resource management, and the type of maintenance applied. Maintenance, therefore, plays a fundamental role in the study of operational availability and in the production process of the asset. Through maintenance, it is possible to improve the operating conditions of assets and add value to their services and products. The focus of this dissertation is to quantify the influence of the factors considered on the operational availability of a production line in the cement industry, by applying failure analysis methodologies and tools, specifically Root Cause Analysis (RCA). This approach aims to increase the operational availability of physical assets in the cement industry by identifying recurrent failure modes for the physical assets under analysis. Based on this analysis, a maintenance plan will be proposed to prevent recurrent failure modes and mitigate those that cannot be entirely avoided. The implementation of this methodology will provide essential information to maintenance teams for optimizing their management and improving the quality of their activities.
