|Abstract: ||MEDIATOR is a negotiation support system (NSS) based on
evolutionary systems design (ESD) and database-centered implementation.
It supports negotiations by consensus seeking through exchange of
information and, where consensus is incomplete, by compromise. The
negotiation problem is shown --graphically or as relational data in
matrix form-- in three spaces as a mapping from control space to goal
space (and through marginal utility functions) to utility space. Within
each of these spaces the negotiation process is characterized by
adaptive change, i.e., mappings of group target and feasible sets by
which these sets are redefined in seeking a solution characterized by a
single-point intersection between them.
This concept is being implemented in MEDIATOR, a data-based micro-mainframe
NSS intended to support the players and a human mediator in
multi-player decision situations. Each player employs private and
shared database views, using his/her own micro-computer decision support
system enhanced with a communications manager to interact with the
mediator DSS. Sharing of views constitutes exchange of information
which can lead towards consensus. The human mediator can support
compromise, as needed, through use of solution concepts and/or
concession-making procedures in the NSS model base. As a concrete
example, we demonstrate the use of the system for group car buying
