Group decision making and quality-of-information in e-Health systems
Lima, Luís; Novais, Paulo; Costa, Ricardo André Fernandes; Cruz, José Bulas; Neves, JoséKnowledge is central to the modern economy and society. Indeed, the knowledge society has transformed the concept of knowledge and is more and more aware of the need to overcome the lack of knowledge when has to make options or address its problems and dilemmas. One`s knowledge is less based on exact facts and more on hypotheses, perceptions or indications. Even when we use new computational artefacts and novel...
Decision making based on quality-of-information a clinical guideline for chroni...
Lima, Luís; Novais, Paulo; Costa, Ricardo; Cruz, José Bulas; Neves, JoséIn this work we intend to advance towards a computational model to hold up a Group Decision Support System for VirtualECare, a system aimed at sustaining online healthcare services, where Extended Logic Programs (ELP) will be used for knowledge re-presentation and reasoning. Under this scenario it is possible to evaluate the ELPs making in terms of the Quality-of-Information (QoI) that is assigned to them, alon...
Quality Management: Concepts and Approaches for Software Projects
Gonçalves, Dulce; Varajão, João; Martinho, Ricardo; Cruz, José BulasIn a world of growing competitiveness, “quality” is a main subject. On recent years, there has been a trend towards the improvement of software projects’ quality. This means improving not only the final software products, but especially the quality of leadership and of project management. It is now recognized that the quality of software products and services can be improved if quality management is accomplishe...
Elder care architecture - A physical and social approach
Marcelino, Isabel; Barroso, João; Cruz, José Bulas; Pereira, AntónioAs we observe society in our days, we can see that people live longer; this means that we have an older population, more likely to have health issues. The special needs presented by the elderly are becoming a major concern for all of us, along with the lack of time demonstrated by society as a whole and, as a consequence, the lack of time is seen when families are not able to take care of their own elders. Many...
A process model for group decision making with quality evaluation
Lima, Luís; Novais, Paulo; Cruz, José BulasIn this work it is addressed the problem of information evaluation and decision making process in Group Decision Support Systems (GDSS). A Multi-valued Extended Logic Programming language is used for imperfect information representation and reasoning. A model embodying the quality evaluation of the information, along the several stages of the decision making process, is presented. This way we give the decision ...
Quality of knowledge in group decision support systems
Lima, Luís; Costa, Ricardo; Novais, Paulo; Analide, César; Neves, José; Cruz, José BulasIn this work it is addressed the problem of knowledge evaluation in a VirtualECare Group Decision Supporting System (GDSS), in terms of an Multi-valued Extended Logic Programming language, which is aimed at sustaining online healthcare services. Indeed, reasoning with incomplete and uncertain knowledge have to be dealt with, due to the particular nature of the healthcare services, where the awful consequences o...
Quality of information in the context of ambient assisted living
Lima, Luís; Costa, Ricardo; Novais, Paulo; Analide, César; Cruz, José Bulas; Neves, JoséWith the use of new computational technologies and novel methodologies for problem solving, recurring to the use of Group Decision Support Systems, normally the problem of incomplete information is marginalized as if we were living in an ideal world. Common sense tells us that in the precise time a decision is make it is impossible to know all the information regarding to it, however decisions must be made. Wha...
VirtualECare: group support in collaborative networks organizations for digital...
Costa, Ricardo André Fernandes; Novais, Paulo; Lima, Luís; Cruz, José Bulas; Neves, JoséCollaborative Work plays an important role in today’s organizations and normally in areas where decisions must be made. However, any decision that involves a collective or group of decision makers is, by itself, complex but is becoming normal in recent years. In this work we present the VirtualECare project (Figure 10), intelligent multi‐agent system able to monitor, interact and serve its customers, which are,...
Ambient intelligence in emotion based ubiquitous decision making
Marreiros, Goreti; Santos, Ricardo; Ramos, Carlos; Neves, José; Novais, Paulo; Machado, José Manuel; Cruz, José BulasAs the time goes on, it is a question of common sense to involve in the process of decision making people scattered around the globe. Groups are cre- ated in a formal or informal way, exchange ideas or engage in a process of argumentation and counter- argumentation, negotiate, cooperate, collaborate or even discuss techniques and/or methodologies for problem solving. In this work it is proposed an agent-based a...
Argumentation-based decision making in ambient intelligence environments
Marreiros, Goreti; Santos, Ricardo; Novais, Paulo; Machado, José Manuel; Ramos, Carlos; Neves, José; Cruz, José BulasIn Group Decision Making argumentation has a crucial role; we have a set of participants, with different points of view that exchange ideas or engage in a process of argumentation and counter-argumentation, negotiate, cooperate, collaborate or even discuss techniques and/or methodologies for problem solving. In this paper we propose an argumentation-based system, where intelligent agents simulates the behaviour...
