Distance education tool selection using novel spherical fuzzy AHP EDAS

Abstract

COVID 19 pandemic, which entered our lives suddenly, caused the change of our classical education system and forced higher education institutions to switch to distance education quickly. During this time, the need for a method that can comprehensively and scientifically evaluate the alternatives of videoconferencing tools to be used in distance education has emerged. This paper proposes a novel hybrid multi-criteria group decision-making (MCGDM) model by integrating the analytic hierarchy process (AHP) and the evaluation based on distance from average solution (EDAS) methodologies. The proposed model is developed with spherical fuzzy (SF) sets, which enable decision-makers (DMs) express their membership, non-membership and hesitancy degrees independently, and in a large three-dimensional spherical space. The applicability of the developed spherical fuzzy AHP EDAS is illustrated through a problem of selecting a videoconferencing tool for distance education. For this purpose, three DMs evaluate five popular videoconferencing tools, namely Zoom, Google Meet, Cisco WebEx, Skype and Microsoft with respect to six criteria, which are expanded with 32 related sub-criteria from the literature to more comprehensively handle the problem. The implications, sensitivity and comparative analyses, limitations and future research avenue are also given within the study.

“…et al [ 40 ] proposed the extended Complex Proportional Assessment (COPRAS) under the PFSs environment, leading to the PF-COPRAS. In the middle of COVID pandemic, Menekşe and Camgöz Akdağ [ 41 ] proposed hybrid multi-criteria group decision-making based on the Analytic Hierarchy Process (AHP), the distance from average solution and spherical fuzzy sets for evaluating videoconferencing platforms. Their results suggest that Zoom was the most suitable platform for distance education during COVID pandemic.…”

“…In this section, we discuss about definitions and some fundamental properties and operations of SFS and SFN based on the past work [28,31,32,[87][88][89].…”

“…SFS is an advanced extension of neutrosophic fuzzy sets [29] and type 2 IFS [30]. SFS provides a number of advantages [31,32] such as (i) Unlike IFS, it considers the sum of membership and non-membership degrees greater than 1. (ii) In contrast to PyFS, it considers the degree of hesitancy.…”
