Fuzzy AHP – DEMATEL Methods To Investigate Passengers’ Decision Factors On Using Public City Bus In An Indonesian Region

Abstract

An advanced public transportation system becomes an indicator for a country. Accordingly, it is essential that the decision-makers (DMs) conduct an initial study based on passengers’ view in order to improve the public transportation services. Since involving multi factors, the problem is often solved using the multi-criteria decision-making (MCDM) approaches. This study aims to examine significant factors on passengers decision making to use public transportation using Fuzzy AHP and DEMATEL. The Fuzzy AHP method is proposed to determine criteria weights so that significant critera are obtained, then the causal relations including the criteria are visualized using DEMATEL. This study demonstrates the integration of the two MCDM methods in a BRT system in the region of Yogyakarta, Indonesia, and invites passengers and the DMs. The result indicated that 21 criteria are identified, while the 11 significant criteria are selected based on the Fuzzy AHP weight – α-cut screening. Besides, the DEMATEL has succeeded in describing the influence relationship for the criteria, where firstly, the significant criteria are classified into cause and effect group and secondly, the two criteria, namely coverage to strategic points and on time arrival, should be put on the top priority list. This study enables the DMs to solve public transportation problems more effectively. However, the follow-up study should be carried out by including other factors such as economic and sustainability to strengthen the decision-making process.

Comparing Power Supply Technologies for Public Transport Buses through the AHP and the Fuzzy DEMATEL Method

“…In this regard, the integration of the AHP method with other appraisal techniques, like, for example, the DEMATEL method in the methodology proposed here, contributes to overlook such drawback, relieving the fatigue experienced by respondents and facilitating the resolution of decision-making problems. Indeed, the AHP is one of the evaluation techniques that is most commonly used in combination with the DEMATEL method [21,41,42], whose effectiveness has been proved in many scientific contributions with applications to various economic sectors [16][17][18][19][20][21][22][23][24][25][26]. This method represents a valid approach for obtaining a visual structural model of the casual relationships among factors when solving complex real-world decision-making problems, like choosing the solution for power supply technology for buses.…”

An integrated fuzzy MCDM model for prioritizing strategies for successful implementation and operation of the bus rapid transit system

“…Nassereddine and Eskandari ( 2017 ) proposed an integrated MCDM technique based on the Delphi method, GAHP, and PROMETHEE to assess the satisfaction levels of passengers from public transportation systems in Tehran. Kurniawan et al ( 2021 ) applied the fuzzy AHP-DEMATEL techniques to address the passengers’ decision parameters on using the BRT system in Indonesia. Deveci ( 2018 ) proposed an interval type-2 fuzzy TOPSIS and GRA-based VIKOR method for the evaluation of customer satisfaction in all the transportation modes in Istanbul.…”
