Pythagorean picture fuzzy set (PPFS) is a combination of Picture Fuzzy 5+1 and theYagcr‘s l"ythagorcan Fuzzy Set [12—14]. In the first part of the paper [17] we introduced some basic notions namely the set operators on PPFS. The missing part in our previous wort: is Fefining the extension of such the operators on the Spherical Fuzzy Sets toward applications of :ztitiaz'zribute group decision making problems. In this second part, we will tackle this issue and preset. some main operators on PPFS such as the picture negation operator, picture t—norm. picture picture implication operators on PPFS. Lastly, the compositional rule of inference in PPFS is presented accompanied with a numerical example.
