Abstract
|
The purpose of this paper is to apply of concept of fuzzy bridge and to extend of notation of fuzzy domination number in fuzzy graph. Fuzzy bridge introduces a new notation of fuzzy domination sets and fuzzy domination numbers such that is consedering for fuzzy graphs with cyclics and vertices are located on cyclics. To check the importance of fuzzy domination numbers based on fuzzy bridge, we compare it to other distinct fuzzy domination numbers and show that fuzzy domination numbers based on fuzzy bridge is optimal.The main method, in this research is based on computations of fuzzy domination number of complete fuzzy graphs with distinct fuzzy vertices and is worked on special and useful fuzzy graphs such as strong 2wheel fuzzy graph and 2complete fuzzy graph. The study on 2wheel fuzzy graph and 2complete fuzzy graph was given for the first time in this paper and are worked via the generalize of 2part of wheel fuzzy graph and complete fuzzy graph which these special fuzzy graphs have many applications on complex networks. In this study, computations of fuzzy domination number of special fuzzy graphs are done based on fuzzy bridge with distinct vertices. The paper includes implications for the development of fuzzy graph, and for modeling the uncertainty problems and applicaions in real world which we consider two modes of real problems.
