Abstract:

TEAMDEC is a Group Decision Support System (GDSS). The development of a GDSS is supported by a broad spectrum of theories and techniques. Two major aspects of GDSS development were considered in TEAMDEC design: HCI and decision-making assistance. These two aspects interact to promote an interactive group decision support system with high quality. Decision guidance using a script-based knowledge representation improves the GDSS's efficiency, effectiveness, and flexibility. The traditional script, however, is relatively inflexible. The proposed application, TEAMDEC, provides a set of solutions

Abstract:

This research was concerned with the collection of empirical data necessary to estimate the effects of decision support tools on the performance of distributed groups. Data was collected in a controlled experimental environment that simulated a geographically-dispersed meeting through the use of videoconferencing and group communication support (GCSS) technology. Results of the use of a Group Decision Support System (GDSS) on group process and outcome variables were mixed. As predicted by the literature the use of a GDSS by distributed groups improved overall group consensus, decision accuracy

This research compared the use of an electronic meeting system tool to a manual group process in large and small groups in a controlled laboratory experiment. Outcomes measured include the quality of decision, the time taken in various stages of the decision making process, and group member satisfaction.

The six independent variables included in this model are group size, the rule by which the group makes a decision, the incentives driving the group, the distribution of useful information within the group, the t

Abstract:

There has been increasing research interest in recent years in using the power of computers to support group work. There have been two main areas of research: experimental research into GDSS supported group work in laboratory settings, and research designed to develop GDSSs which are effective, efficient and acceptable to their users. However, there have been some contradictory findings from these two areas of research. The developmental effort has shown great promise in relatively controlled developmental settings. At the same time, experimental research has indicated that GDSSs may not provi

Abstract:

Knowledge acquisition is not only the most important but also most difficult task knowledge engineers face when they begin to develop expert systems. One of the first problems they encounter is the need to identify at least one individual with appropriate expertise who is able and willing to participate in the development project. They must also be able to use a variety of techniques to elicit the knowledge that they require. These include such traditional knowledge acquisition methods as interviewing, thinking-aloud protocol analysis, on-site observation, and repertory grid analysis. As exper

The software architecture that has been developed is intended to guide the development of such support systems and is based on a library of procedural abstractions called elemental-engines.

Abstract:

Group Support Systems (GSS) are systems, normally involving the use of Information Technology, that have been designed to support groups of people meeting to undertake some task. By providing an additional channel of communication, GSS attempt to reduce group process losses, such as domination of the group by one or more members, and to enhance positive aspects of the group process, for example a group member thinking of a new and useful idea as a result of awareness of the contribution of other group members. A number of different types of GSS have been developed involving different levels of

In group decision support systems, understanding the roles, dynamics and relationships between participants is imperative to streamlining the decision-making process. This is especially true when decision makers have varying interests. Research has shown that decision-making processes amongst groups with varying interests will often reach bottlenecks with issues, such as unwillingness to share information, or a limited ability of the participants to share ideas at the same time.

Abstract:

Multi-Criteria Decision Making (MCDM) problems are often associated with tradeoffs between performances of the available alternative solutions under decision making criteria. These problems become more complex when performances are associated with uncertainty. This study proposes a stochastic MCDM procedure that can handle uncertainty in MCDM problems. The proposed method coverts a stochastic MCDM problem into many deterministic ones through a Monte-Carlo (MC) selection. Each deterministic problem is then solved using a range of MCDM methods and the ranking order of the alternatives is establi

Abstract:

Group Decision Support Systems (GDSS) have been designed to support groups of people engaged in the cooperative working activities of a meeting. The interactions of a group of people working together in a meeting are termed the "group process" whereby certain factors or input variables influence the group process which in turn characterize the group process outcomes. A review of the work in this field has revealed the absence of a standard organizing framework in GDSS research that adequately models this group process and identifies those variables recognized as characterizing the group proces

Communication, Deliberation, and information access are, in turn, constrained by limited attention and fading memory. Finally group members are only willing to
