区间值Vague集作为Vague集的一种有用推广,已经在系统控制以及智能决策等方面有较为广泛的研究与应用.针对不确定系统处理中常出现的模糊决策问题,通过将决策方案的约束条件属性集转化成区间值Vague集,并综合考虑约束条件属性肯定出现的区间值程度以及肯定不出现的区间值程度和未知是否出现的含糊(犹豫)程度区间,给出一个基于区间值Vague数的记分函数和区间值Vague集的有效的多属性模糊决策方法,使得决策更加合理更具弹性.最后通过一个实例表明我们所提出的方法在不确定系统决策中确是简便可行的.
Interval-valued vague set,as a useful generalization of vague set,has achieved great success in many application areas,such as system control and intelligent decision. By regarding the set of constraint condition attributes as an interval-valued vague set and considering all the interval degree of membership,non-membership and hesitation (or abstention) of the constraint conditions,an effective multicriteria fuzzy decision making method based on our proposed score function of interval-valued vague value is presented for handling fuzzy decision problem frequently occurred in uncertain system processing. At last,a numerical example is given to illustrate the effectiveness and practicability of the presented method.
