  • A Fuzzy Logic model to enhance quality management on R&D units
    Publication . Abreu, António; Santos, Ricardo; Calado, João Manuel Ferreira; Requeijo, José
    Nowadays, Higher Education Institutions (HEIs), are becoming even more competitive, with the public ones, facing at the same time a greater restriction on public funding. Therefore, HEIs, have to be more effective and more efficient as well, on pursuing their own goals, which includes Research and Development (R&D) units as well. Such demands can be achieved, by enhancing R&D`s global performance. Therefore, the use of a framework such as European Foundation for Quality Management (EFQM), can bring value to an organization with the characteristics of a R&D unit. This work presents a new integrated method based on EFQM model, by using Fuzzy Logic, to enhance the organizations overall performance. The applicability of the proposed approach is demonstrated by a case study in a R&D unit, where an initial performance evaluation takes place, by using RADAR`s Logic approach. The proposed method, based on Fuzzy Logic, is then applied, followed by the identification of the strength points as well as the improvement areas, according to the EFQM framework. Then, the improvement actions with high priority are determined, followed by the correspondent action measures.

    Publication . Abreu, António; Martins, José Moleiro; Calado, João Manuel Ferreira
    Currently, companies to be competitive must achieve high rates of innovation and respond quickly to market needs. According to a number of managers and researches innovation is crucial for companies to stay “alive." Taking into account several reports, the development of co-innovation networks based on a collaborative environment is the best strategy to support innovation projects. However, the absence of mechanisms to detect and even anticipate potential risks of innovation based on a collaborative approach is an obstacle to the proliferation of this way of working. To address this issue, this paper discusses an approach based on fuzzy reasoning for analyzing the level of risk in co-innovation projects. It is discussed how this approach can be applied to co-innovation projects within the contexto of a collaborative ecosystem. At last, it is discussed the benefits, and challenges found on experimental results from a Portuguese co-innovation network.

  • Vantagens da aplicação da filosofia six sigma business scorecard em projectos de manutenção
    Publication . Requeijo, José; Abreu, António; Calado, João Manuel Ferreira
    De acordo com a perspectiva tradicional a função manutenção é conotada como uma atividade secundária consumidora de recursos humanos e financeiros, razão pela qual muitas empresas utilização como estratégia de manutenção há já vários anos, a subcontratação dos serviços de manutenção a empresas especializadas. No entanto, as estratégias de gestão da manutenção herdadas do passado estão cada vez menos adaptadas às necessidades e exigências dos processos modernos de produção. A necessidade em efetuar operações de manutenção em sistemas cada vez mais complexos requer acesso a vários tipos distintos de competências que as pequenas e médias empresas especializadas em serviços de manutenção geralmente não possuem. Como resultado, as empresas prestadoras de serviços de manutenção são confrontadas com o seguinte dilema: desenvolver as competências em falta, por meio de seus próprios ativos, fazendo investimentos por vezes elevados, ou em alternativa capitalizar as competências que podem ser disponibilizadas por outras empresas de manutenção no contexto de um ecossistema colaborativo. Entende-se por ecossistema colaborativo uma qualquer coligação entre um conjunto de várias entidades (especialistas e empresas) autónomas, geograficamente distribuídas e heterogéneas do ponto de vista operacional, que decidem estabelecer relações de colaboração entre si, como processo, para atingir objetivos comuns ou compatíveis de forma mais eficiente. Este artigo tem como objetivo ilustrar o papel da abordagem Six Sigma Scorecard como instrumento de gestão para a melhoria da qualidade no serviço prestado num contexto colaborativo. O artigo começa por discutir os princípios da filosofia Six Sigma e do Balanced Scorecard. Em seguida, é discutido de que modo se pode fazer a associação das duas metodologias como instrumento de gestão. Por último, é discutido como é que esta abordagem pode ser aplicada na avaliação das atividades de manutenção no contexto de um ecossistema colaborativo.
  • A fuzzy logic model to evaluate the lean level of an organization
    Publication . Abreu, António; Calado, João Manuel Ferreira
    This paper is concerned with the development of a holistic fuzzy logic model to evaluate the lean thinking environment in an organization. The development of such a model was based on a qualitative assessment approach, including quantitative basis, whose development has been based on fuzzy logic reasoning. Recourse to the use of fuzzy logic is justified by its ability to cope with uncertainty and imprecision on the input data, as well as, could be applied to the analysis of qualitative variables of a system, turning them into quantitative values. The proposed approach was structured with the aim of to achieve a model able to cope with the specificities ofany kind of organization regardless of their nature, size, strategy and market positioning. Furthermore, the proposed methodology allows the systematically identification of constraint factors existing in an organization and, thus, provide the necessary information to the manager to develop a holistic plan for continuous improvement. To evaluate the robustness of the proposed approach, the methodology was applied to a maintenance and manufacturing aeronautical organization.
  • Aplicação da lógica difusa para avaliar o nível lean de uma organização
    Publication . Abreu, António; Calado, João Manuel Ferreira; Vargas, João
    Neste artigo apresenta-se um modelo baseado em lógica difusa com o objectivo determinar o nível lean de uma organização. O modelo desenvolvido assenta numa abordagem de avaliação qualitativa, incluindo bases quantitativas, cujo desenvolvimento foi suportado pela utilização de lógica difusa. O recurso à utilização da lógica difusa justifica-se pela sua capacidade de conseguir lidar com a incerteza e a imprecisão dos dados de entrada, bem como, ser igualmente aplicável na análise de variáveis qualitativas de um sistema, transformando-as em valores quantitativos. Uma grande vantagem do modelo desenvolvido é que este poderá ser reajustado a qualquer tipo de organização independentemente da sua natureza, dimensão, estratégia e posicionamento no mercado. Além disso, o modelo proposto possibilita a identificação de forma sistemática dos factores de constrangimento existentes na organização e fornecer assim a informação necessária para que a gestão desenvolva um plano holístico de melhoria contínua. Visando a avaliação da robustez da abordagem proposta neste artigo, o modelo foi aplicado a uma organização de manutenção e fabricação aeronáutica, sendo apresentados os resultados obtidos e efectuada a correspondente análise crítica dos mesmos. In this paper in order to determine the level of a lean organization a model based on fuzzy logic has been developed.

Recourse to the use of fuzzy logic is justified by its ability to cope with uncertainty and imprecision of the input data, as well as, could be applied to the analysis of qualitative variables of a system, turning them into quantitative values. A major advantage of the developed model is that it can be adjusted to any organization regardless of their nature, size, strategy and market positioning. Furthermore, the proposed model allows the identification systematically of constraint factors existing in the organization and thus provide the necessary information for the management to develop a holistic plan for continuous improvement. To assess the robustness of the approach proposed in this paper, the model was applied to a maintenance and manufacturing aeronautical organization, being presented the corresponding results and made a critical analysis of them.
  • A new approach for agile teams' allocation in open innovation projects
    Publication . Anes, Vitor; Abreu, António; Dias, Ana; Calado, João Manuel Ferreira
    Due to constant change in the marketplace, it can be difficult for companies to secure the material, human, and technological resources necessary for competitive innovation activities. In this sense, and to overcome these constraints, the open innovation model is a quite successful approach, where the sharing of resources among companies allows the formation of an innovation ecosystem. However, the execution time of these projects can be negatively affected if the performance of each work team is not taken into account. In this work, the application of the agile approach in open innovation projects is proposed as a way to reduce the uncertainty both in the execution time of the projects and in the respective implementation costs. In this sense, a methodology for optimal team assignment for agile teams in open innovation projects according to their performance on each project task is developed to determine the optimal team assignment that leads to the shortest project execution time. This methodology will support decision making in the project management of open innovation projects, especially in the selection of the internal and external work teams that will participate in a given innovation project. The application of the proposed methodology is illustrated with an example describing and analyzing the different steps of its application. The results show that with the proposed methodology it is possible to take into account the performance of each team when calculating the project execution time and that the project execution time varies depending on the assignment of the agile teams to the project tasks. It is also shown that it is possible to determine the optimal assignment with the shortest project execution time.
