Title: CO-OP: A DECISION SUPPORT SYSTEM FOR COOPERATIVE MULTIPLE CRITERIA GROUP DECISION-MAKING
Abstract: This research deals with the analysis and design of group decision support systems (GDSS). The implementation of Co-oP, a GDSS for multiple criteria group decision making, suggests the need for two design strategies. First, from a multiple criteria decision making (MCDM) viewpoint, this research supports the conceptualization of a unified MCDM framework. The interfacing and combined use of various multiple criteria decision methods help a MCDM-based GDSS support a wide range of decision situations, attenuates the difficulty of information search, allows division of decision making tasks, and permits consensus seeking analyses.
Second, from a decision support system viewpoint, this research suggests that GDSS should be distributed, loosely coupled and process-driven. A distributed and loosely coupled GDSS architecture provides autonomy and flexibility for individual decision making, and homogeneity and simplicity for group problem solving. More important, only process-driven GDSS are able to deal with the unpredictable nature of group problems since collective decision processes have been shown to be the only elements in a GDSS that are (i) stable enough to fit into most collective problems, (ii) reasonably structurable to be implementable, and (iii) sufficiently controllable to guarantee appropriate use.
Co-oP implements these design principles. It runs on a network of individual workstations using a process-driven and multi-window user interface. The Co-oP model component consists of a set of individual MCDM methods, techniques of aggregation of preferences, and a consensus seeking algorithm to support negotiation. Formal and informal communication among group members is monitored by a group norm filter which is adaptable to a large number of collective decision situations.
