Abstract :When the information of hesitant fuzzy sets dynamically varies with time, the hesitant fuzzy soft sets are
w
extended to the time-series hesitant fuzzy soft sets through the introduction of the time parameter. Based on the concept of
w
time-series hesitant fuzzy soft sets, the fundamental operational rules are defined, the corresponding operation results are
w
analyzed and the properties are discussed. A decision method of time-series hesitant fuzzy sets is given, and it can be veri-
fied the feasibility and effectiveness of the proposed method with a practical example.
Key words :soft sets; hesitant fuzzy sets; hesitant fuzzy soft sets; time-series fuzzy soft sets; time-series hesitant fuzzy soft sets
摘 要:针对犹豫模糊软集的信息随着时间动态变化的情形,引入时间参数,将犹豫模糊软集推广为时序犹豫模糊
软集。基于时序犹豫模糊软集的概念,定义了其基本的运算法则,分析对应的运算结果并讨论其运算性质。给出了
时序犹豫模糊软集的一种决策方法,并通过实例表明了该方法的有效性与可行性。
