Abstract

In the past, much of the GDSS research has focused on developing computerenvironments and their effects on group work, and has given relatively littleattention to support for group facilitation. However, recent experimental studies point out that facilitation may be a critical factor in GDSS effectiveness, and research on facilitation in GDSS is only now coming into focus. Some efforts for facilitation have been made to measure the degree ofgroup consensus, but their contribution to facilitation is limited. Fuzzy theory can quantitatively simulate the fuzziness of mankind's judgmental behavior, dispose of the problems of decision making with a more elastic way, conform to mankind's thinking. Therefore, this study plans to combine "Fuzzy Muliple Attribute Decision Making Method" and "GDSS" to establish a method which supports facilitation, in hope to supply the following information at any time in a group decision process, so that thegroup facilitator can make strategies to help the group reach a consensus :1.The degree of consensus. 2.Decision makers whose opinions have the highest consistency with other members' opinions in the group. 3.The division status of subgroups whose opinions are obviously distinct from each other. 4.Thealternatives that hinder the group to reach a consensus. 5.The criteria thathinder the group to reach a consensus. 6.The independency of alternatives and criteria. Finally, based on the established calculations in this study, a prototype of GDSS that supports facilitation will be built and put to practical implementation.
