Group decision and negotiation support in evolving,nonshared information contexts

Based on evolutionary systems design (ESD), group decision and negotiation support in evolving, nonshared information contexts is discussed. A non-shared information context — one without full information sharing — is associated with what has been loosely called a noncooperative context in the group decision and negotiation support systems (GDNSS) literature. Without full information sharing, we have a game with incomplete information that, in general, is evolving. The paper discusses how the GDNSS, MEDIATOR, supports evolution of the group problem representation — a process of consensus seeking (through information sharing, here partial) subject to problem adaptation and restructuring within which compromise is possible.
