Abstract(s)
O presente trabalho incide sobre a realização de um estudo quanto à aplicação e implementação
de um sistema de informação capaz de efetuar a monitorização e análise de dados de produção
numa empresa da indústria metalomecânica.
Atualmente, não é efetuada a monitorização dos dados, sendo apenas registada manualmente
alguma informação, numa frequência reduzida. Quanto às ordens e registos de produção, estes são
efetuados através do ERP utilizado na empresa. No entanto as operações de produção não são
controladas. Neste sentido, acresce o problema dos dados serem adicionados no ERP de modo
manual, não sendo possível garantir a sua fiabilidade, e podendo decorrer um considerável
intervalo de tempo entre um acontecimento e o seu registo.
Procedeu-se à avaliação da situação atual, de modo a compreender os problemas e as necessidades
da gestão de informação no chão de fábrica. Tendo em conta esta análise, definiu-se a visão para o
sistema de gestão da informação, tendo-se decidido que a solução indicada era um Manufacturing
Execution System (MES). Assim, foram definidos os requisitos e as funcionalidades que o sistema
deve cumprir. Posto isto, efetuou-se o redesenho dos processos analisados, para que refletissem a
visão e os requisitos estipulados.
Estas ideias foram depois aplicadas na avaliação de soluções MES disponíveis no mercado. Para
cada uma das soluções avaliaram-se o cumprimento de requisitos e o desempenho face a critérios
de avaliação. Através da atribuição de ponderações aos critérios, obteve-se uma pontuação para
cada uma das opções, resultando na seleção da solução com melhor pontuação.
Este resultado permitiu concluir que o cumprimento de requisitos do sistema é o critério de
avaliação com mais preponderância. Dessa forma, globalmente, as características e funcionalidades
particulares da solução são mais importantes para a tomada de decisão que outras variáveis mais
associadas à empresa desenvolvedora
The present report focuses on conducting a study on the application and implementation of an information system capable of monitoring and analysing production data in an enterprise of the metal-mechanical industry. Currently, the monitoring of data is not carried out, with only some information being recorded manually, in a reduced frequency. As for the production orders and records, these are made through the ERP used in the enterprise. However, the production operations are not controlled. In this regard, there is also the problem of data being added manually in the ERP, not being possible to guarantee its reliability, and a considerable time gap may occur between an event and its record. The current status was evaluated, in order to understand the problems and needs of information management on the shop floor. Taking into account this analysis, the vision for the information management system was defined, and it was decided that the indicated solution was a Manufacturing Execution System (MES). Thus, the requirements and features that the system should fulfil were defined. That being said, the processes analysed were redesigned, so that they reflected the vision and the stipulated requirements. These ideas were then applied to the evaluation of MES solutions available on the market. For each of the solutions, compliance with requirements and performance against evaluation criteria were evaluated. By assigning weightings to the criteria, a score was obtained for each of the options, resulting in the selection of the solution with the best score. This result made it possible to conclude that compliance with system requirements is the most significant evaluation criterion. Therefore, overall, the particular features and characteristics of the solution are more important for the decision making than other variables more associated with the developer company
