Evidence Theory in Picture Fuzzy Set Environment

Picture fuzzy set is the most widely used tool to handle uncertainty with account of three membership degrees, namely, positive, negative, and neutral such that their sum bound up 1. It generalization existing intuitionistic sets. This paper studies interval probability problems picture sets belief structure. The function a vital represent uncertain information in more effective manner. On other hand, Dempster–Shafer theory (DST) combine independent sources evidence low conflict. Keeping advantages these, present paper, we concept for environment using DST. Under this, define distribution discuss its properties. Finally, an illustrative example related decision-making process employed illustrate application presented work.
