摘　　要：利用Borda函数和语言量词将因素状态向量转化为因素的序分值向量,并由序分值向量构造出一类新的激励型状态变权向量,据此建立一种基于语言量词的变权综合决策模型.为说明此决策模型反映语言量词语义的效果,对一些典型语言量词所构造的变权综合决策模型和相应的OWA算子进行了对比分析.最后给出一个应用实例.Factor state vector is transferred into quantifier guided order index vector by applying Borda function and linguistic quantifier.With the quantifier guided order index vector,a kind of new encouraging state variable weight vector is presented.Therefore,a variable weight averaging operator based on linguistic quantifier is constructed.In order to verify the capability of reflecting the linguistic value＇s semantics,some variable weight averaging operators based on several typical linguistic quantifiers and the corresponding OWA operators guided by the same linguistic quantifiers are compared.Finally,an example is presented.
