摘要
为了描述在不同时刻内涵发生变化的模糊集合,本文通过综合模糊集合、语言动力系统(Linguistic dynamic systems,LDS)及动态规划,提出了时变论域与动态模糊规则理论,将时变论域分为离散型与连续型两类,每一类分为递增型、递减型及波动型三种,并讨论如何在时变论域上建立动态模糊规则以及进行词计算,最后给出时变论域下的语言动力学轨迹.
In order to describe the fuzzy set whose intention varies with time interval, we present the theory of time- varying universe of discourse and dynamic fuzzy rules by synthesizing fuzzy set, linguistic dynamic systems （LDS）, and dynamic programming. The time-varying universe discourse is divided into two types： discrete type and continuous type, and each type is sorted into incremental, decremental, and mixed classes. Then, how to build dynamic fuzzy rules and how to compute with words on time-varying universe of discourse are discussed. Finally, the linguistic dynamic orbits on the time-varying universe of discourse are given.
