Abstract

Information overload is a key issue in group decision. A heuristics, called ''take-the-best'', has been shown useful to face multicriteria decisions while reducing information overload: when making decisions people often take criteria in a predefined order, the first criterion which discriminates the alternatives at stake is used to make the decision. In order to rationalize group work, Briggs and de Vreede have proposed collaboration design patterns, called thinkLets. This article presents the LogicalMulticriteriaSort which can be seen as a generalization of the take-the-best heuristics. It also proposes to consider criteria one at the time but once a criterion has been found discriminating it is kept in a record, and the process is iterated. The thinkLet is supported by a GDSS, based on Logical Information Systems, which gives an instantaneous feedback of each micro decision and keeps tracks of all of the decisions taken so far. The LogicalMulticriteriaSort ThinkLet guarantees more fairness and speed than the ChauffeurSort thinkLet. It also avoids the need to give artificial values and weights to the criteria as opposed to the Multicriteria thinkLet. A successful test case is reported.
