A DSS FOR COOPERATIVE MULTIPLE CRITERIA GROUP DECISION MAKING (original) (raw)

Protocols for Cooperative Multiple Criteria Decision Processes

Proc. of the IFIP WG

In the group decision process a set of human decision makers work together to achieve common judgement on several issues. Decision conferences are usually synchronous, face-to-face meetings in decision room environments. If several similarly equipped remote decision rooms are connected via real-time video and/or audio links, a media space is created. In individual meeting rooms or multimedia technology created media spaces, meetings and decision making processes are supported by computer technology (e.g. network connected workstations) besides other forms of analog and/or digital communication technologies such as projected shared video screen, telephone, fax. This computational support usually covers different phases of the meeting (from brainstorming, through formal voting procedures to collaborative minutes writing), and uses computer network services for human participants and/or their software actors. In this paper a computational Reference Model of Distributed Group Decision Support Systems (RM-DGDSS) is presented within the framework of the Reference Model of Open Distributed Processing [RM-ODP 92]. The RM-DGDSS defines a distributed architecture for supporting a group of decision makers connected via computer network. Reference model defines a vision, a strategic outline for the standardization of this kind of distributed processing as well as the description and standardization of basic ideas, entities, algorithms of distributed group decision process. It provides a common language and basic understanding for researchers and developers of this area. The ultimate aim of this contribution is the initiation of an international cooperation for specification of a multiparty protocol (PDS) specialized for group decision support.

Asynchronous and Distributed Multi-Criteria Decision Making Using a Web-Based Group Support System

IGI Global eBooks, 2011

A detailed model for designing a Web-based Multi-Criteria Group Support System (MCGSS) is presented. The model is based on the Analytic Hierarchy Process (AHP) and uses the intensity of preferences of group members rather than simple voting procedures. This approach offers several advantages over simple voting mechanisms, including a much richer picture of both individual and group positions and more equitable decision-making. A prototype system, with a user-friendly graphical user interface (GUI), has been developed and used to analyze an experimental group decision process over the Internet.

A Contemplation of Group Decision Support Systems

2009

A Decision Support System (DSS) is an interactive computer-based information system that supports decision making and sometimes knowledge management. Essentially, it is fortitude of organizations, associations, corporation of information about the enterprise concerned, for support of assessment-making process. In assimilation with that enterprises relay on DSS tools, techniques and models in order to seek recommendations in business activities and strategies. One of the most important but vast areas specified for DSS is a Group Decision Support System (GDSS), that is a kind of electronic meeting system, a collective technology design for meetings and group works via a human computer interaction for effective group decision making. Though this is a relatively new and emerging field of DSS, there remain some problems and issues to be solved in GDSS such as its requirement of real time operation, process losses, time consuming and high cost required for its group coordination etc. This paper presents a review of numerous researchers' efforts regarding GDSS and their impacts. The rationale of our study in this paper is in twofold: first is to review the literature, highlight the shortcomings and their core ideas or strengths. Another perspective is to show a critical evaluation by comparison and contrast. The contribution of this paper is on surveying many researchers efforts pertaining to GDSS.

Group decision support systems

Decision Support Systems, 1987

An exciting new concept is emerging in the area of decision support. This involves the development of computer-based systems for use by groups of people who are jointly responsible for making decisions. Known as "Group Decision Support Systems" (GDSS) they can be useful to committees, review panels, executive board meetings, task forces, and groups of managers who work together on either a regular or one-time basis. Theprecise design of a G DSS will vary depending on the proximity of group members to one another and the duration of the decision-making session. This paper presents an overview of the GDSS concept and explores issues related to the design, implementation, and study of these systems.

A DSS Architecture for Multiple Participant Decision Making

IEEE, 1994

A comprehensive decision support system @SS) is designed for use in multiple participant-multiple criteria decision making situations. The proposed DSS consists of six major components that are described in the paper. Within the model base management system component of the DSS, the graph model for conflict resolution is suggested as a technique for systematically studying real world disputes.

23 Applied Research on Group Decision Support Systems

In the 1980s, computing and information technology underwent a fundamental transformation from centralized systems inaccessible to most users to personal computers and networks that put computing within reach of everyone.

A framework for supporting distributed group decision-making

Decision Support Systems, 1992

A decision-making group has been defined [6] as two or more people jointly responsible for Group decision support systems (GDSS) have been pro-detecting a problem, elaborating on the nature of posed as tools for aiding the group decision making process, the problem, generating possible solutions, Research in GDSS has focused primarily on facilitating group evaluating potential solutions, or formulating meetings. However, meetings form only one aspect of the group decision problem solving process. In fact it is desirable strategies for implementing solutions. In other to reduce the number of meetings, especially if the group words, the group is engaged in the decision promembers are in geographically distant locations. The need for cess together, as opposed to an individual engaged meetings can be reduced if the group is provided with a system in the process. Since decision support systems which will allow the group members to exchange information (DSSs) were proposed to aid an individual in and expertise on a continuous basis rather than only during meetings. In this paper we propose a framework for such a decision-making, a natural extension of the consystem which we designate a distributed group decision sup-cept is to develop DSSs to support groups. A DSS port system (DGDSS). The DGDSS works in conjunction with designed to aid group decision making has been an organizational information system composed of a network defined as a group decision support system of knowledge based systems. This network is utilized to sup-(GDSS). port information and expertise exchange between group members on a continuous basis. A key factor in group decision making which is absent in individual decision making is the need Kevwords: Expertise sharing, Group decision support systems, for interaction between the group members during Knowledge, Networked knowledge-based systems, the decision making process. This has led researchers to focus on communication or informa

Multi-Criteria Decision Support Systems. Comparative Analysis

In a highly competitive business environment the right decision may bring success to a company while the wrong one may lead to collapse. Making the right choice is a difficult task, especially if there are multiple criteria. Therefore companies to remain competitive in a highly-demanding market have to know how to make decisions right. This article aims to compare existing computerized multi-criteria decision support systems and provide recommendations on implementing them in Kazakhstan. Analysis includes review of multi-objective decision making methods and tools available to facilitate the work of decision makers, selection a group of DSS software to study, comparing the key characteristics of selected multi-criteria DSSs, identifying the best alternative(s) and providing final recommendations for accepting such tools by decision makers in Kazakhstan. Authors of the article have selected and analyzed 10 decision-making software packages and developed their suggestions on adopting them in Kazakhstan. Results and conclusion were summarized in the article.
