What is Criteria (C)

In recent years, with the development of the internet, there has been an increase in interest in the internet thanks to other technological developments. In the face of increased user demand, hotel webpages have to maintain high quality of service for a sustainable success. The authors present the Pythagorean fuzzy TOPSIS method to evaluate the hotel webpages. In this study, the most suitable hotel web page has been selected among the five hotel web page alternatives based on 13 criteria according to three experts' opinions. In contrast to precise numbers in TOPSIS method, the merit of fuzzy TOPSIS method is to handle the fuzzy numbers to evaluate the alternatives. Experts cannot express certain evaluations explicitly when using precise values during making decisions. However, the use of linguistic variables provides great success in decision making under uncertain environments. Pythagorean fuzzy number is used to define the weights of the criteria according to three experts' opinions. Five alternative hotel web pages are ranked by using Pythagorean fuzzy number.
