The degree of hesitancy of a vertex in a hesitancy fuzzy graph depends on the degree of membership and non-membership of the vertex. We define a new class of hesitancy fuzzy graph, the intuitionistic hesitancy fuzzy graph in which the degree of hesitancy of a vertex is independent of the degree of its membership and non-membership. We introduce the idea of β-product of a pair of hesitancy fuzzy graphs and intuitionistic hesitancy fuzzy graphs and prove certain results based on this product.

The biggest challenge of managing mobile interpretative device is encouraging visitors to have the mobile experience. Thus, in the research of the mobile application of the Leeum, a short orientation session as a treatment was provided to survey participants to make them use of a mobile experience and to solve the problem of hesitancy. Based on the research data, their satisfaction with visiting experience and with using the application appeared to be relatively high. However, several problems such as intrusiveness, isolation, head-down effect and technical problems needed to be improved to have a promising future.

Based on the geometrical representation of a generalized intuitionistic fuzzy set, we take into account all three parameters describing generalized intuitionistic fuzzy set, propose a method to calculate the correlation coefficient for generalized intuitionistic fuzzy sets in finite set and probability space, respectively, and discuss some properties of correlation and correlation coefficient of generalized intuitionistic fuzzy sets.
