Many managerial decisions involve consideration of more than a single criterion. Despite the development of multicriteria decision models (MCI)M), decision support systems (DSS), and group decision support systems (GDSS), there is inadequate success in supporting multicriteria decision making. This study explores the possibility of embedding decision guidance within MCDM GDSS. We outline guidel...

Ž . Groups using group decision support systems GDSS for addressing organizational problems is an evolutionary process. An analytical model incorporating evolutionary processes exists, capturing this adaptation in the group decision-making Ž . process. This model is based on the genetic algorithm GA and can be used to estimate GA parameter values from experimental data. This research effort exa...

This paper presents a procedure that allows us to determine the preference structures (PS) associated to each of the different groups of actors that can be identified in a group decision making problem with a large number of individuals. To that end, it makes use of the Analytic Hierarchy Process (AHP) (Saaty, 1980) as the technique to solve discrete multicriteria decision making problems. This...

One facet of group decision making that has escaped close scrutinization is the effect of individual biases and group biases on group work. In this paper we present a theoretical framework for using data mining based group memory to overcome the biases in group decision making situations. By studying the patterns extracted from the group memory data, the group members can develop a better under...

There is a paucity of experimental data addressing how peers influence adolescent risk-taking. Here, we examined peer effects on risky decision-making in adults and adolescents using a virtual social context that enabled experimental control over the peer "interactions." 40 adolescents (age 11-18) and 28 adults (age 20-38) completed a risk-taking (Wheel of Fortune) task under four conditions: i...
