Abstract:

For the multiple attribute group decision-making problems with Pythagorean hesitant fuzzy numbers, this paper presents a multiple attribute group decision making approach based on Pythagorean hesitant fuzzy cross entropy. Adefinition of Pythagorean hesitant fuzzy cross entropy is proposed. Taking entropy as a measure of the difference degree on decision information, models to determining the weight of decision makers and attributes in multi-attribute group decision making are put forward. An approach of TOPSIS based on Pythagorean hesitant fuzzy cross entropy is developed. Meanwhile, an example on location of photovoltaic power station project is provided to illustrate the feasibility and effectiveness of the proposed method.

Key words: multi-attribute group decision making, Pythagorean hesitant fuzzy cross entropy, weight of attributes, TOPSIS
