Operations on Intuitionistic Fuzzy Graphs.

In this paper, we determine operations on intuitionistic fuzzy graphs. The purpose is to apply the results to the combination of human trafficking routes. However, we use arbitrary dual t -norms and t -conorms to form these combinations since they determine more accurate models than maximum and minimum. We illustrate our results by combining two human trafficking routes from Central America to the United States. [ABSTRACT FROM AUTHOR]
