- A Fuzzy Logic model to enhance quality management on R&D unitsPublication . Abreu, António; Santos, Ricardo; Calado, João Manuel Ferreira; Requeijo, JoséNowadays, 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.

- Management of innovation ecosystems based on six sigma business scorecardPublication . Calado, João Manuel Ferreira; Requeijo, José; Abreu, António; Dias, AnaIn the present context, companies to be competitive must develop high-performance innovation capabilities that enable them to respond quickly to market needs. However, the lack of tools and methodologies to assess the performance of innovation projects in an integrated way remains an obstacle. The paper begins by discussing the principles of Six Sigma and the Balanced Scorecard for performance evaluation. Next, the advantages of the Six Sigma Business Scorecard are discussed as a tool to support the evaluation of performance in innovation projects. Finally, the advantages of their application in the context of a collaborative ecosystem are discussed. It is illustrated that the BSC ensures that top management pays attention at any time to the specific elements of the Six Sigma implementation that are not working as planned, providing a link between strategy and quality initiatives assuring customers satisfaction in innovation projects.
- Buildings lean maintenance implementation modelPublication . Abreu, António; Calado, João Manuel Ferreira; Requeijo, JoséNowadays, companies in global markets have to achieve high levels of performance and competitiveness to stay "alive".Within this assumption, the building maintenance cannot be done in a casual and improvised way due to the costs related. Starting with some discussion about lean management and building maintenance, this paper introduces a model to support the Lean Building Maintenance (LBM) approach. Finally based on a real case study from a Portuguese company, the benefits, challenges and difficulties are presented and discussed.
- Vantagens da aplicação da filosofia six sigma business scorecard em projectos de manutençãoPublication . Requeijo, José; Abreu, António; Calado, João Manuel FerreiraDe 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.
- Implementation of statistical process control in a bottling line in winery industryPublication . Abreu, António; Requeijo, José; Calado, João Manuel FerreiraIntroduction: The great demand of the markets has led to situations in which the production systems are characterized by the production of several batches but of small size. This new paradigm requires that adequate techniques be developed, both in terms of planning and in terms of Statistical Process Control (SPC), since there may be situations where it is not possible to collect enough data to properly estimate the parameters of the process (mean and variance). Objectives: Implementation of Statistical Process Control techniques in a wine industry in order to improve its final product. Methods: Whenever there is not enough data to properly estimate the parameters of the process, the suggested approach, is to adopt the developments proposed by Charles Quesenberry. In this case, the statistic of the sample at time i is transformed through the estimations of the process parameters using the information obtained (data) until the instant (i-1). The univariate study of process capability is performed through the capability indices QL and QU. Thus, in this paper, two situations of statistical control are addressed, one in which a univariate study is done, based on Q charts, and another in which the multivariate study is made, based on the MQ charts. Results: This study comprised the implementation of the SPC) of a wine brand that has low production volumes, in the process of bottling wine, which is considered a critical step since some care is needed, such as avoiding the occurrence of microbiological contaminations or oxidation of the wine. Conclusions: Whenever it is not possible to apply traditional control charts the use of the control Q charts (univariate analysis) and the control MQ charts (multivariate analysis) are the most appropriate choice not only for the control of one or more products but also for several sets of quality characteristics.
- Control charts to support trust monitoring in dynamic logistics networksPublication . Abreu, António; Requeijo, José; Calado, João Manuel Ferreira; Dias, AnaNowadays, companies to be competitive must develop capabilities that enable them to respond quickly to market needs. According to some managers, the strategy is the development of dynamic logistics networks based on a collaborative environment. However, the absence of mechanisms to detect and even anticipate potential opportunistic behaviour is an obstacle to the proliferation of this way of working. The article aims to understand the role of trust to sustainability of collaborative processes. The paper begins by discussing the trust properties. It is then discussed how statistical control charts can be used to support the trust monitoring of each member within a collaborative ecosystem. The control charts’ tools suggested in this paper are the Z control charts for trust level monitoring and the Zi capacity index. Finally, it is discussed how this approach can be applied to dynamic logistics networks within the context of a collaborative ecosystem.

According to the traditional perspective the maintenance function is counted as a secondary activity consuming human and financial resources, which is why many companies, use as maintenance strategy for several years, the subcontracting of maintenance services to specialized companies. However, the need to perform maintenance operations on increasingly complex systems requires access to several distinct types of skills that small and medium-sized firms specialized in maintenance services generally do not have. This paper aims to illustrate the role of the Six Sigma Scorecard approach as a management tool for improving quality in service provided in a collaborative context. The article begins by discussing the principles of the Six Sigma and the Balanced Scorecard backgrounds. It is then discussed how the two methodologies can be combined as a management tool of maintenance activities. Finally, it is discussed how this approach can be applied in the assessment of maintenance activities in the context of a collaborative ecosystem.
