A Contemplation of Group Decision Support Systems

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.
