摘要
综合模糊聚类技术和粗糙集理论中的信息熵原理,提出了一种多因素决策中确定各因素权重分配的新方法。利用模糊聚类分析对数据进行聚类,并提取最佳聚类;基于粗糙集中信息熵原理确定各因素的权重分配。算例结果表明:方法合理有效,具一定的可行性。
The accuracy and reliability of multi-factor decision-making was partly depended on the reasonable attribute weight allocation.In order to perform weight allocation reasonably and effectively in multi-factor decision-making,a multi-factor weight allocation method was proposed based on the fuzzy clustering analysis in fuzzy sets and the entropy theory in rough sets in this paper.The source data was clustered by fuzzy clustering analysis,and the best clustering was extracted.The multi-factor weight allocation was determined based on the entropy theory in rough sets.The calculation result of an example showed that the proposed approach was reasonable and feasible.
