Whereas conventional Decision Support System (DSS) helps individual decision makers, Group Decision Support System (GDSS) is designed to help groups of managers who are jointly responsible for making complex strategic decisions. Up to the present, most of researches in strategic GDSS have focused on the hardware such as email system, electronic meeting system, video conferencing system, etc. On the other hand, it is needed to study on the process of strategic group decisions which assists to structure complex decision problems and resolve uncertain ones. In particular, among the process the pooling mechanisms of individual opinions are required for making the decisions. However, it is not at all done to aggregate the diverse opinions of individuals in GDSS area. This research focuses on two issues in GDSS : the process of strategic group decision making and the aggregation of a number of individual opinions. For the purpose, We first propose a framework of Strategic Decision Making Process (SDMP) in which to be participated multi-persons, i.e., a group. Second, the multi-opinion pooling methods which need to each phase of the process of strategic group decision are presented. Based on the pooling methods, we develop a opinion pooling support system (OPSS) to improve the facility of group decision making. The developed system is illustrated with an example.
전략적 의사결정(Strategic Decision Making)은 비정형화된 문제로 많은 불확실성을 가지고 있다. 이러한 의사결정은 일반적으로 여러명이 함께 참여하는 그룹 의사결정 형태를 취하게 된다. 최근, 중견 관리자나 전문가 그룹이 효율적으로 의사결정을 수행하도록 돕기위한 그룹 의사결정 지원시스템(Group Decision Support System)이 활발하게 연구되고 있다. 그러나 현재까지 대부분의 그룹 의사결정 지원시스템이 하드웨어부분에 치중되어 연구되고 있다. 본 논문에서는 첫째, 다수의 사람이 함께 참여하는 전략적 의사결정 프로세서(The Process of Strategic Group Decision Making)을 제안하고, 둘째, 이러한 프로세서중 다수의 의견을 취합하기 위한 의견취합 지원시템(Opinion Pooling Support System)을 개발하고자 한다. 의견취합 지원시스템은 기존에 개발된 여러가지의 의견취합 방법(Pooling Methods)에 기반을 두고 개발하였다.
