摘要
提出了一种改进的多层次交互式决策模型的权重确定方法.该模型首先由参加决策的上级邀请专家确定权重约束范围和初始参考权重向量,再由各下级在专家约束下,根据自己的偏好确定各自的权重,然后提交上级,并由上级进行综合,确定系统的参考权重;然后反馈给各单元,由各单元再次确定各自的权重,并提交上级进行综合,这样不断反馈,直至满足一定要求后终止,由上级最终确定系统综合权重.最后,以一个算例来说明本文方法的实施过程.
The authors put forward a kind of improve of the weights of the attributes by intercommunicating based on multilevel model. Firstly, the superior invites the experts to determine the variety of the weights and the initial vector, the subordinates determine the weights by themselves, according to their preferences and the restrictions, and return to the superior, watch a synthesis. Then the feedback is given to each subordinate, back to the before-mentioned process, repeatedly. The process ends until meeting the rules. An example given at the end of the paper shows the process of this method.
