....modeling, Negotiation support, Water level management 1. Introduction Group Decision Support Systems (GDSS) can have very different functions. They can aim to improve communication among the group members and to help decision modeling and even to implement group decision making techniques [4]. Our focus is the use of modeling approaches based on Multiple Criteria Decision Making (MCDM) to group decision support. Recent summaries of related work can be found, e.g. in [3] and [34] Kersten and Noronha [23] discuss web based negotiation support. However, so far there is very little true ....

The focus of the analysis is on two types of tasks: decision making tasks and routine office processes. Research on the support of muti participant decision making has been classified by DeSanctis and Gallupe (1987), in a widely accepted scheme, which distinguishes between three levels, based on the degree of support provided to the group. Level 1 systems provide technical functionality aimed at removing common communication barriers and facilitating information exchange; level 2 systems provide decision ....

INTRODUCTION The AGAP system is a distributed group decision support system for project analysis and evaluation support. It intends to provide level one and some level two group support (according to DeSanctis [7]) to decision makers working on project analysis and evaluation. It s main goal is group analysis and evaluation of several projects, each characterized by its own data, although some data can be shared between projects. On each project, or on several at once, different analysis methods are ....

In a GSS, users interact with and through a computer mediated communication system to do collaborative work (DeSanctis and Gallupe 1987). Organizations can use GSS to enhance communication within and across groups.

Workflow systems can thus be labeled coordination technologies, while other tools for informal interaction like group decision support systems (GDSS) DeSanctis87] are better defined as collaborative . A basic assumption in the remainder of this paper, is that we should reject any aprioristic bias towards one or the other type of systems.

They proposed a multidimensional taxonomy of research variables in GSS research. This taxonomy was driven by three factors: group size, communication channel (face to face vs. computer mediated) and task type. At about the same time, Hiltz (1988) proposed the systems contingency approach. Like ....
