一种决策者判断一致性的聚类方法

对于产量为模糊区间数的生产计划群决策问题,考虑不同产品生产的优先度和决策者权重对决策者判断一致性度量的影响,给出了相对加权一致度的一种计算方法。当群决策的结果不一致时,提出了依据相对加权一致度对决策者进行聚类的方法,并给出了每一类决策者决策结果的综合方法。最后通过算例说明了方法的应用过程。

A Method of Clustering Analysis Based on Consensus of Group Judgment

For a group decision problem in production planning which regards production quantity as a triangle fuzzy number,a consensus measure is proposed based on products’ priorities and decision makers’ important weights.When the group judgment doesn’t reach consensus on a production planning,it is suggested that decision-makers to be clustered according to the consensus measure for the convenience of aggreating the group’s decision,the aggregation approach for each cluster of decision-maker is also described.At last,an example is given to illustrate the process of our approach.
