چکیده

Although many measures of similarity between intuitionistic fuzzy set (IFS) have been proposed in the literature, some existing similarity measures are not always effective in some cases. A main reason is that existing similarity measures have not or little considered degree of hesitancy in intuitionistic fuzzy set. In this paper, based on this foundation that the degree of hesitancy in intuitionistic fuzzy set and decision maker’s attitude to indetermination information are taken into account, a dynamic similarity measure is proposed for measuring the degree of similarity between IFSs. To demonstrate the efficiency of the proposed dynamic similarity measures, the existing similarity measures between IFSs are compared with the dynamic similarity measure between IFSs by numerical examples. It is shown that the proposed similarity measures can deal with counter-intuitive cases more effectively and reasonably than some existing methods. Finally, dynamic similarity measure is applied to pattern recognition.

Weighted similarity measure on interval-valued fuzzy sets and its application to pattern recognition

A new approach to define the similarity measure betweeninterval-valued fuzzy sets is presented. The proposed approach isbased on a weighted measure in which the normalized similaritiesbetween lower functions and also between upper functions arecombined by a weight parameter. The properties of this similaritymeasure are investigated. It is shown that, the proposed measurehas some advantages in c...

ORDERED INTUITIONISTIC FUZZY SOFT MODEL OF FLOOD ALARM

A flood warning system is a non-structural measure for flood mitigation. Several parameters are responsible for flood related disasters. This work  illustrates an ordered intuitionistic fuzzy analysis that has the capability to simulate the unknown relations between a set of meteorological and hydrological parameters. In this paper, we first define ordered intuitionistic fuzzy soft sets and est...
