Abstract(s)
Na presente dissertação estudou-se o desenvolvimento e aplicação de um sistema de planeamento e controlo das atividades de manutenção preventivas e corretivas de ativos. O caso de estudo foi desenvolvido na empresa STEP Consolidated, Lda onde a grande maioria das manutenções efetuadas são realizadas após a ocorrência de uma falha.
Para o efeito, utilizou-se a metodologia de avaliação da criticidade de equipamento proposto por Fernando D’Alessio Ipinza para identificar os ativos mais críticos, isto é, os que sustentam os processos produtivos da organização. Neste sentido, e de acordo com a sua função e importância, são desenvolvidos e implementados planos de manutenção, bem como procedimentos de manutenção e listas de verificação de periodicidade semanal, mensal e anual.
De forma a viabilizar a implementação destas práticas foi desenvolvida uma aplicação informática com recurso ao Microsoft® Excel®. Esta aplicação permitiu, além de outras funcionalidades, criar ordens de trabalho, analisar o histórico de avarias dos ativos e de acompanhar os indicadores de desempenho de manutenção ao nível organizacional, técnico e económico.
Com a implementação de intervenções planeadas e realizadas de forma periódica em cada ativo, o controlo de todas as atividades de manutenção e a consulta imediata de indicadores de manutenção atualizados em tempo real, espera-se contribuir de forma significativa para a tomada de decisões eficazes e tornar a gestão de manutenção mais eficiente, permitindo não só evitar avarias inesperadas e diminuir custos, mas também prolongar a vida útil dos ativos.
In this dissertation, the development and application of a system for planning and controlling preventive and corrective asset maintenance activities was studied. The case study was developed at the company STEP Consolidated, Lda where most of the maintenance carried out is done after the occurrence of a failure. For this purpose, the equipment criticality assessment methodology proposed by Fernando D'Alessio Ipinza was used to identify the most critical assets, that is, those that support the organization's production processes. In this sense, and according to their function and importance, maintenance plans are developed and implemented, as well as maintenance procedures and weekly, monthly, and annual periodicity checklists. To make the implementation of these practices feasible, a computer application was developed using Microsoft® Excel®. This application made it possible, in addition to other functionalities, to create work orders, analyze the history of assets breakdowns and to monitor maintenance performance indicators at the organizational, technical, and economic level. With the implementation of interventions planned and carried out periodically on each asset, the control of all maintenance activities and the immediate consultation of maintenance indicators updated in real time, it is expected to contribute significantly to more assertive decision making and effective and make maintenance management more efficient, allowing not only to avoid unexpected breakdowns and reduce costs, but also to extend the useful life of assets.
