“…Some recent studies have adopted the DEMATEL approach for evaluating complex problems, such as the user interface analysis based on the DEMATEL approach [ 9 ], failure sorting evaluation system [ 10 ], the innovation policy portfolios of Taiwan’s SIP Mall industry, based on the DEMAEL approach [ 11 ], the causal analytical method of group decision-making, based on the fuzzy DEMATEL approach [ 12 ], the evaluation of an airline safety management system [ 13 ], the analysis of value-created systems for science (technology) parks [ 14 ], the service selection of vehicle telematics system [ 15 ], the integrated model of relation structure analysis and performance evaluation for hot spring hotels, based on the hybrid Multiple Criteria Decision Making (MCDM) technique [ 16 ], the integrated approach of selection of strategic alliance partners for the airline industry [ 17 ], the selection model of outsourcing provider for the airline industry [ 18 ], the evaluation of supply chain performance based on the DEA (Data Envelopment Analysis) and balanced scorecard technique [ 19 ], the portfolio selection of strategic project for national research institutes based on the hybrid MCDM method [ 20 ], the quality education service for Hospitality, Tourism, and Leisure Undergraduate Programs (HTLPs) [ 21 ], the critical factors of implementing a program for international Multivariate Imputation via Chained Equations (MICE) professionals, based on the hybrid MCDM model [ 22 ], determining the causal relationships of the antecedents of organizational citizenship behavior (OCB) for the hospitality industry, using the fuzzy DEMATEL [ 23 ], the service position model of package tour services by the hybrid MCDM approach [ 24 ], the sustainable development strategies of industrial tourism, based on the IOA-NRM approach [ 6 ], and the blockchain critical success factors of a sustainable supply chain [ 25 ]. This study divides DEMATEL into five steps: (1) calculate the original average matrix, (2) calculate the direct influence matrix, (3) calculate the indirect influence matrix, (4) calculate the full influence matrix, and (5) analyze the NRM (Network Relation Map).…”
