An Approach for Evaluating Website Quality in Hotel Industry Based on Triangular Intuitionistic Fuzzy Numbers

Abstract

Compared to fuzzy numbers, intuitionistic fuzzy numbers provide greater opportunities for solving complex decision-making problems, especially when they are related to ambiguities, uncertainties and vagueness. However, their use is more complex, especially when it comes to ordinary users. Therefore, in this paper an approach adopted for evaluating alternatives on the basis of a smaller number of some more complex evaluation criteria is proposed. The approach is based on the use of linguistic variables, triangular intuitionistic fuzzy numbers, and the Hamming distance. At the end, a case study of hotels' websites evaluation is given to demonstrate the practicality and effectiveness of the proposed approach, together with its limitations and weaknesses. Additionally, a new procedure for ranking intuitionistic fuzzy numbers is proposed and its use is verified.

An integrated SWOT–extended PIPRECIA model for identifying key determinants of tourism development: The case of Serbia

“…MCDM methods have become increasingly popular in recent decades, having been applied in many different research areas (Zavadskas and Turskis 2011;Gavade 2014;Zavadskas, Turskis and Kildienė 2014;Stojčić et al 2019). They are especially convenient for application in situations where a greater number of criteria are included, against which the decision-maker (DM) should perform the evaluation process and make the final decision (Stanujkic et al 2017b;Stanujkic et al 2017c;Popovic, Stanujkic and Karabasevic 2019). These techniques are useful in facilitating decisions and increasing the reliability of decisions.…”

“…These techniques are useful in facilitating decisions and increasing the reliability of decisions. In addition to resolving various business problems, MCDM methods are also used to facilitate decisions in tourism with regard to policy (Liu, Tzeng and Lee 2012;Michailidou, Vlachokostas and Moussiopoulos 2016), competitiveness (Wu 2011;Zhang et al 2011;Huang and Peng 2012;Gómez-Vega and Picazo-Tadeo 2019), sustainable tourism and ecotourism (Michalena, Hills and Amat 2009;Aliani et al 2017;Arsić, Nikolić and Živković 2017), location and destination selection (Chou, Hsu and Chen 2008;Cheng, Su and Tan 2013;Morteza et al 2016;Aksoy and Ozbuk 2017;Puška, Stojanović and Maksimović 2019), service quality (Rozman et al 2009;Tseng 2011;Zoraghi et al 2013;Wu and Wang 2014), and website quality (Hu 2009;Akincilar and Dagdeviren 2014;Stanujkic, Zavadskas and Tamošaitienė 2015;Stanujkic et al 2017b).…”

Special Issue on Circular economy

“…MCDM enables the selection of a suitable alternative from a finite set of alternatives while respecting the values of the criterion attributes, i.e. it enables decision-making in the presence of multiple, often conflicting criteria [17][18][19][20][21][22]. Ishizaka and Nemery [23] indicate the growing use of MCDM methods because these methods primarily enable better decision-making and adoption of long-term and sustainable solutions.…”

A New Method of Multi-Criteria Analysis for Evaluation and Decision Making by Dominant Criterion

“…Multi-criteria analysis or multi-criteria optimization, as a method and technique for evaluation and decision making, has been developed in different scientific disciplines, such as operational researches, statistics, management science, computer science (Ivanovic, 1973;Saaty, 1982;Mardani et al, 2015a;Mardani et al, 2015b;Brans and Vincke, 1985;Roberts and Goodwin, 2002). Multi-criteria decision analysis has been and continues to be applied in various fields of expertise, such as finance, logistics, transportation, marketing, public services, energy management, environmental planning (Dong and Xu, 2016;Huang et al, 2011;Stanujkic et al, 2017;Mardani et al, 2015aMardani et al, , 2015bTurskis and Zavadskas, 2011;Zavadskas et al, 2017;Hashemkhani Zolfani et al, 2013). In particular, in economics (Zavadskas et al, 2016a(Zavadskas et al, , 2016b and in engineering (Zavadskas et al, 2016c;Šaparauskas et al, 2011;Zavadskas et al, 2014).…”
