Mediator是一个基于进化系统设计(ESD)和以数据库为中心的实现的谈判支持系统(NSS)。它支持通过交换信息寻求协商一致的谈判，在协商一致不完整的情况下，支持通过妥协进行谈判。谈判问题以图形或矩阵形式的关系数据表示在三个空间中，作为从控制空间到目标空间和(通过边际效用函数)到效用空间的映射。在这些空间中，协商过程的特征是自适应变化，即群体目标和可行集的映射，这些集被重新定义，以寻求它们之间的单点相交的解决方案。这一概念正在Mediator中实现，Mediator是一个基于数据的微型主机NSS，旨在支持多参与者决策情况下的参与者和人类调解人。每个玩家使用他/她自己的带有通信管理器的微型计算机决策支持系统来与调解人决策支持系统进行交互，从而使用私有和共享的数据库视图。交换意见构成信息交流，可以达成协商一致意见。人类调解人可以根据需要，通过使用NSS模型库中的解决方案概念和/或让步程序来支持妥协。作为一个具体的例子，我们演示了该系统在团体购车决策中的使用。
Mediatoris 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 inMediator, 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 decisions.
