Abstract: Based on the needs of intelligent decision making, we combine the trapezoidal fuzzy number with Pythagorean fuzzy sets, and give the notion of trapezoidal fuzzy number Pythagorean fuzzy sets and its entropy measure. We give four kinds of constructive functions for trapezoidal fuzzy number Pythagorean fuzzy sets entropy and prove their algebraic properties. Finally, we provide a decision rule and decision model by using the trapezoidal fuzzy number Pythagorean fuzzy sets entropy.

Key words: trapezoidal fuzzy number, Pythagorean fuzzy set, trapezoidal fuzzy number Pythagorean fuzzy set entropy, decision rule.
