Aggregation of Preferences Based on FSAM in GDSS

Aggregation plays a central role as a means of combining all opinions that are expressed by group members in a group decision support system (GDSS). In this paper, we propose a new epsiv-ASA (Aggregation based on Situation Assessment) algorithm to reflect a decision situation in the aggregation process. Although some research findings showed the importance of cultural factors in GDSS, most of them did not present how to implement cultural factors in GDSS. To handle this problem, we present a proposal for reflecting status differentials in GDSS. It may be used to reflect cultural differences in GDSS design. It is a further step toward the integration of cultural factors into existing GDSS design.
