A Hybrid Model with Spherical Fuzzy-AHP, PLS-SEM and ANN to Predict Vaccination Intention against COVID-19

Abstract: This study aims to identify the key factors affecting individuals’ behavioral vaccination intention against COVID-19 in Vietnam through an online questionnaire survey. Differing from previous studies, a novel three-staged approach combining Spherical Fuzzy Analytic Hierarchy Process (SF-AHP), Partial Least Squares-Structural Equation Model (PLS-SEM), and Artificial Neural Network (ANN) is proposed. Five factors associated with individuals’ behavioral vaccination intention (INT) based on 15 experts’ opinions ar… Show more

“…For example, fresh insights can be gained into the effect of restroom cleaning on satisfaction, a self-evident basic need for the traveling public, particularly during this COVID-19 period. Finally, by drawing on the secondary data used by the study, future studies can evaluate ASQ and passenger satisfaction using mathematically simple yet powerful MCDM (multi-criteria decisionmaking) and machine learning tools [100,101]…”

“…Subject norms and social media were shown to be associated with getting the COVID-19 vaccination. The items on these two factors were adapted from the research mentioned above [7] , [8] , [9] and re-adjusted to fit the COVID-19 vaccination scenario (see subject norm and social media items in Table 2 ).…”

“…λ max calculates by averaging the numbers of the last column of Table 7, which is equal to 7.29. Finally, CI and CR calculate using Equations ( 1) and (2) [24]. After performing the calculations, each criterion's final weights were obtained in the AHP method, as shown in Figure 6.…”

“…In 2021, Nguyen et al used a hybrid fuzzy AHP MCDM to organize the priorities of the medical community and government during the COVID-19 crisis in Vietnam [23]. In another study by Nguyen, fuzzy AHP and machine learning approaches were used to predict vaccination intention against COVID-19 [24]. Entropy is another weighing method that has been widely used in recent years.…”
