Role-based collaborative model of group decision support system

Aiming at the communication and coordination problems of group members in the group decision support system, the structure of role-based collaborative group decision support system model (Role Cooperating Group Decision-making Support System, RCGDSS) is built by inducting the role collaboration to the group decision support system and then the role-based collaborative formal description of RCGDSS is given. After analyzing the advantages and disadvantages of the distribution control mode and centralized control mode, the role-collaborative control mode based on CBS is proposed. Furthermore, it is described that how to implement the role - coordination parts in RCGDSS.
