Standardization of communication between organizational decision units

A computational Reference Model of Distributed Group Decision Support Systems (RM-DGDSS) is described. This Reference Model is a supplement of the standardized Reference Model of OSI (Open Systems Interconnection) and can be a candidate for standardization in ODP (Open Distributed Processing). The RM-DGDSS defines a distributed architecture environment for supporting a group of decision makers connected via computer network. Entities of the Reference Model and their relationship are presented as well as the relation between the RM-DGDSS and Reference Model of ODP (RM-ODP). Research and development towards the standardization of specialized protocols for decision support (PDS) are outlined.
