摘要
利用两模糊数之间的距离公式,将模糊数之间的比较转换为模糊数与纵轴距离之间的比较。在此基础之上定义了模糊数空间上的序关系,并证明了它们的一些性质。这种方法的排序效果与人们的直觉是一致的且不悖逆于实数的自然序。利用距离方法定义的序关系,便于理解与计算机实现。
By use of the distance formula of two fuzzy numbers,a comparison between the fuzzy numbers will be converted into a comparison on distance of the fuzzy numbers and the longitudinal axis.On this base,it defines the order relationship on the fuzzy number and proves some of their properties.This sorting method is consistent to people＇s intuition and the real number.By use of the order relation defined by the distance method,it is easy to understand and be realized by the computer.
