- Robust design and statistical process control in a collaborative environmentPublication . Navas, Helena V. G.; Requeijo, José; Abreu, AntónioNowadays, enterprises in global markets have to achieve high levels of performance and competitiveness to stay “alive". In order to be competitive enterprises must develop capabilities that will enable them to respond quickly to market needs. According to several authors and as frequently mentioned by reports from practical case studies, one of the most relevant sources of competitive advantage is the involvement of enterprises in collaborative networks. However, in spite of this assumption, it is also frequently mentioned that the lack of operational tools tailored to collaborative networks is not available yet and might be an obstacle for a wider acceptance of this paradigm. In this context, the collaborative networks need new statistical tools, new approaches and concepts of quality improvement. Starting with a brief discussion about the nature and the role of some tools in order to support the development of robust design, this paper introduces some discussion about the application advantages of product design in a collaborative environment as a contribution to a future identification of methodologies, approaches that are suitable for collaborative contexts.
- 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.
- Seis sigma business scorecard no desenvolvimento de projetos de manutenção num contexto colaborativoPublication . Requeijo, José; Abreu, António; Calado, João Manuel Ferreira; Dias, A. S. M. E.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 utilizam como estratégia de manutenção há já vários anos, a subcontratação dos serviços de manutenção a empresas especializadas. No entanto, 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. 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. 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.
