Abstract
A picture fuzzy set is an extension of intuitionistic fuzzy set. In this set, a new parameter called neutral value of an object is incorporated. Based on this set, the picture fuzzy graph is defined and investigated by several scientists. Picture fuzzy graph is a new type of fuzzy graph, and it is used for solving many real life problems. In this chapter, the concept of picture fuzzy set is presented. It also introduced the picture fuzzy graph and investigated some useful properties of picture fuzzy graph. Some fundamental terms like degree of a vertex, order and size of picture fuzzy graph, strong picture fuzzy graph, complete picture fuzzy graph, independent strong and independent weak picture fuzzy edge, bipartite picture fuzzy graph, complement of a picture fuzzy graph, path, strength of a path, connectedness, homomorphism, isomorphism, automorphism, Cartesian product, composition, etc. are defined and presented some properties. An application is provided to select best airline route among multiple paths.
