Decision processes for solving group decision making problems are composed of two phases: (i) aggregation and, (ii) exploitation. When experts that participate in the group decision making process are not able to express their opinions using a same expression domain, then the use of information assessed in different domains, i.e., heterogeneous information, is necessary. In these cases, the inf...

Two studies investigated the impact of group norms for maintaining consensus versus norms for critical thought on group decisions in a modification of the biased sampling paradigm (G. Stasser & W. Titus, 1985). Both studies showed that critical norms improved the quality of decisions, whereas consensus norms did not. This effect appeared to be mediated by the perceived value of shared and unsha...

Affinity diagramming is a commonly used contextual design practice for which many tools have been developed. However, experts and novices alike eschew tool use, instead using traditional paper and whiteboard methods. This paper presents observations of traditional affinity diagramming sessions, focusing on three areas of consideration—shared awareness, cognitive offloading, and understanding, o...

Conflict resolution in decision-making groups is studied using a System Dynamics model. The model is developed using a grounded-theory approach. Some preliminary results are shown. The results seem to be in line with much empirical research done in the management literature about conflict and conflict resolution at the group level of analysis. Ideas for further research are discussed. Introduct...

Multiple attribute decision analysis (MADA) problems in the situation of belief group decision making (BGDM) are a special class of decision problems, where the attribute evaluations of each decision maker (DM) are represented by belief functions. In order to solve these special problems, in this paper, TOPSIS (technique for order preference by similarity to ideal solution) model is extended by...

The need for negotiation and decision making among collaborative modelers stems from their desire to reconcile their different positions, priorities and preferences. This requires them to engage in an argumentative negotiation process so as to achieve consensus. A number of methods can be used to aggregate their judgements and priorities thus helping them to reach consensus. In this paper we sh...

Previous research shows that groupware increases the exchange of information for groups, but that the additional comments do not necessarily lead to better decisions. Lack of individual information processing and information overload have been noted as probable causes. Poor attention to information and poor integration of information may cause lack of information processing. Therefore, this stu...

A trace monitor observes an execution trace at runtime; when it recognises a specified sequence of events, the monitor runs extra code. In the aspect-oriented programming community, the idea originated as a generalisation of the advice-trigger mechanism: instead of matching on single events (joinpoints), one matches on a sequence of events. The runtime verification community has been investigat...
