An integrated fuzzy model for evaluation and selection of mobile banking (m-banking) applications using new fuzzy-BWM and fuzzy-TOPSIS

Abstract

Mobile technology has revolutionised various business processes. Banking is one of them. Traditional banking operations are gradually changing with the introduction of efficient mobile technologies. Mobile banking (m-banking) has recently emerged as an innovative banking channel that provides continuous real-time customer service. It is expected that the market for m-banking will expand in the near future. There are currently various types of m-banking applications in the market. However, ranking and selecting efficient applications is difficult due to the involvement of multiple factors. As of now, very few studies have reported the m-banking application selection framework, left scope for further research. The current study proposes an m-banking application selection model based on a combined fuzzy best–worst method (fuzzy-BWM) and fuzzy Technique for Order of Preference by Similarity to Ideal Solution (fuzzy-TOPSIS). The research was carried out in several stages, beginning with the identification of potential factors and progressing to pair-wise comparisons and the final ranking of the applications. The fuzzy set theory was applied to handle the ambiguity of the decision maker. In the first stage, fuzzy-BWM was used to determine the weight of the factors. Further, fuzzy-TOPSIS was applied to rank the m-banking applications. The present study has adopted a new fuzzy BWM, which differs significantly from the existing fuzzy-BWM, to solve the nonlinearity problem of optimisation. The applicability of the proposed model has been demonstrated through a real-life case study. The efficacy of the model has been further examined by performing a sensitivity analysis. The study observed application functionality, convenience, and performance expectancy as significant factors in selecting an m-banking application, followed by performance quality, security, and compatibility. The proposed model can assist financial institutions and customers to overcome the challenges of choosing an appropriate m-banking application. The proposed model can be used to benchmark the m-banking applications in the market.

A Fuzzy Improvement Testing Model of Bank APP Performance

“…(3) The time of data collection is short, which can help enterprises quickly grasp the opportunity for improvement and meet the need for enterprises to pursue fast and accurate decision-making. (4) Making good use of the fuzzy performance evaluation, analysis and improvement model [28,29] can continuously enhance the bank APP operation performance and allow users to complete banking operations without going out. Not only does the model increase the bank's operating efficiency, but it also eases traffic congestion and parking as well as benefits energy saving and carbon reduction.…”

Comparative analysis of fuzzy multi-criteria decision-making methods for quality of service-based web service selection

“…To rank options, the FT technique is employed. Recently, many researchers [18], [19] used FT to rank alternatives in various application areas such as IT risk analysis, stealth fighter aircraft selection. The FT algorithms is given in ( 18)-( 27).…”

Analysis of Efficiency and Productivity of Commercial Banks in Turkey Pre- and during COVID-19 with an Integrated MCDM Approach

“…In addition, in order to eliminate the deficiencies of the intermittent EDAS method in practice, the model was updated and changed for the interval type data. In a study in which mobile banking rankings on seven Indian banks were investigated, Roy and Shaw [67] proposed an m-TOPSIS banking application selection model based on a combined fuzzy best-worst method (fuzzy-BWM) and a fuzzy TOPSIS (fuzzy-TOPSIS). In the analysis, the fuzzy-BWM technique was used to determine the weights of the factors, and the fuzzy-TOPSIS technique was used to rank the m-banking applications.…”
