The selection of mobile phones based on the dimensions of qualities by word-of-mouth approach

These days, mobile phones play a major role in the lives of many customers and are an integral component of society. The price of this instrument has decreased and its functionalities have increased, making it a vital tool even if it was formerly thought of as a luxury. Customers choose certain mobile phone models based on their needs. The quality attributes of mobile phones are quantified in quality dimensions. The majority of this information is divulged through word of mouth (WOM). In this study, the opinions of 350 students regarding four mobile phone brands were gathered using Garvin’s quality of dimensions. Subsequently, these opinions were assessed using an integrated TOPSIS with an interval-valued intuitionistic fuzzy numbers technique. Finally, four phone brands were ranked according to students’ opinions.
