Group decision making problems aim to manage situations in which two or more experts need to achieve a common solution to a decision problem. Different rules and processes can be applied to solve such problems (e.g. majority rule, consensus reaching, and so on), and several models have been proposed to deal with them. Some difficulties may arise in group decisions, being most of them caused by ...

In group decision making (GDM) processes, prior to the selection of the best alternative(s), it would be desirable that experts achieve a high degree of consensus or agreement between them. Due to the complexity of most decision making problems, individuals’ preferences may not satisfy formal properties. ‘Consistency’ is one of such properties, and it is associated with the transitivity propert...

While considering processes of decision making we often encounter the problem of incomplete information. In group decision making (GDM) problems each decision maker is supposed to provide a matrix that describes his/her preferences over the set of given options. However, we have to take into account that an expert can not be able to define his/her preferences about all the options. Usually the ...

In Multiagent Systems (MAS), various activities are related to decisions involving a group of agents such as negotiation, auctions and social choice. Group Decision Making (GDM) specializes in situations where a group of agents need to pick one of possibly many options from a set and commit to it. We intend to provide a new GDM framework in which the agents are able to employ abductive reasonin...

[Context and motivation]: Goal-Oriented Requirements Engineering (GORE) and Multi Criteria Decision Analysis (MCDA) are two fields that naturally complement each other for providing decision support. Particularly, GORE techniques complement MCDA in terms of problem structuration and visualization of alternative evaluation, and MCDA techniques complement GORE in terms of alternative elimination ...

All decision-making units (DMUs) in the private or public sector are provided with a set of inputs of different values by their governing decisionmaker (GDM), and are required to generate a set of outputs. The GDM is able to reallocate the inputs/outputs among the DMUs to estimate the maximum absolute decision making efficiency of the sector. Serial models are presented to manage the interactio...
