运用传统的模糊集进行模糊型群决策时存在一定的困难,而Vague软集是一种处理不确定信息的重要工具。为此,给出了一种加权的Vague软集间相似度定义,并运用Vague软集对备选方案进行评判;在此基础上运用正态云模型进行群体一致性评判,将基于Vague软集的模糊群决策方法应用于供应商选择问题中,结果表明,Vague软集能极大地提高模糊群决策的科学性和有效性。
運用傳統的模糊集進行模糊型群決策時存在一定的睏難,而Vague軟集是一種處理不確定信息的重要工具。為此,給齣瞭一種加權的Vague軟集間相似度定義,併運用Vague軟集對備選方案進行評判;在此基礎上運用正態雲模型進行群體一緻性評判,將基于Vague軟集的模糊群決策方法應用于供應商選擇問題中,結果錶明,Vague軟集能極大地提高模糊群決策的科學性和有效性。

There exist some difficulties if the traditional fuzzy set is used for fuzzy group decision making problem, and the Vague soft set is an important tool of processing uncertain information. For this reason, a weighted resemblance degree of the Vague soft set is defined and the Vague soft set is used to evaluate the alternatives. On this basis, the normal cloud model is used to calculate group consistency. Finally, the fuzzy group decision making method which based on the Vague soft set is used in supplier selection decision problem, and the data of the results indicate that the Vague soft set theory can greatly improve the scientificalness and effectiveness of fuzzy group decision making.
