A Heuristic Model of Network-Based Group Decision Making for E-Services

Decision making in groups can ease personal biases which enables the participants discuss, argue and coordinate the ideas of coalitions. The final outcome of a group decision making process reaches a consensus decision. However, using one particular model should not preclude the consideration of other models or other means of assessing group decision making. This study aims to provide a Delphi-based group decision model of collective intelligence. Many research mainly focus on how to attain the consensus; however, rarely further investigate the expert selection process. Hence, this work (1) furnishes a group decision process that takes into account the people from social network, (2) empowers the collective intelligence from social network, and (3) leverages the decision effort of experts.
