Group decision-making methods based on hesitant N-soft sets

In this article, we introduce a new hybrid model called hesitant N-soft sets by a suitable combination of hesitancy with N-soft sets, a model that extends N-soft sets. Our novel concept is illustrated with real life examples. Moreover, we investigate some useful properties of hesitant N-soft sets and construct fundamental operations on them. We describe potential applications of hesitant N-soft sets in group decision making, and finally we present some group decision-making methods as algorithms. (C) 2018 Elsevier Ltd.
