分布式决策支持系统中结论冲突消除

THE STRATEGY OF CONCLUSION CONFLICT RESOLUTION IN DISTRIBUTED DECISION SUPPORT SYSTEMS

在分布式环境下，群体成员在求解同一决策问题的过程中，由于成员之间认知上存在差异，获得的结论可能出现冲突。本文引进了ＡＴＭＳ，用标签记录模型假设，用Ｄｅｍｐｓｔｅｒ－Ｓｈａｆｅｒ信度来度量不确定性，引进了ＡＩ中相关制导回溯技术，设计了一种辩论环境，将结论冲突消除分三种情况来讨论：①信度合成；②信度修改；③模型结构修改。提出了一种结论冲突消除方法──辩论／回溯／修改法。

Under the distributed environment, the conclusion conflict may emerge in the process of solving decision problems, due to the difference of cognizance among group members. In this paper, with the help of ATMS and dependency--directed backtracking technique, a method of conclusion con'flict resolution, i. e., the disputationbacktrack ing-modification method, is presented.
