Novel Concept of Cubic Picture Fuzzy Sets

Abstract

As a new extension of a cubic set, the notion of a cubic picture fuzzy set is introduced. The propose work is separated into two portions. Firstly, establish the concept of cubic picture fuzzy set and explore associated properties. Secondly, establish internal (external) cubic picture fuzzy sets and define P-order and R-order union and intersection. Deliver some examples to support of established P-order and R-order union and intersection of internal (external) cubic picture fuzzy sets.
