An IFS-IVIFS-DEMATEL Method to Identify Critical Success Factors of Cross-Department Coordination of Emergency Management

Cross-Department Coordination of Emergency Management (CDCEM) is considered a critical dimension in China to solve the problem emergency management. The Decision Experiment and Decision-Making Trial Evaluation Laboratory (DEMATEL) method used build structural correlation criteria uncertain environments identify success factors (CSFs). There are coupling correlations one-way for interrelationship comparisons between selected CDCEM. Therefore, there two different assessment scales. However, most previous studies applied DEMATEL with single scale CSFs. To fill this gap, an IFS-IVIFS-DEMATEL provided comprehensively CSFs CDCEM study. intuitionistic fuzzy set (IFS) regarded as scales correlation, interval-valued (IFIVS) correlation. types were transformed into interval information improved approach. Then, using conduction among factors, comprehensive matrix was constructed. After that, ranking central degree cause according traditional obtained. Finally, case study Nanjing’s illustrated demonstrate that proposed more suitable reasonable. It found “cross-department organization”, communication transmission”, “information sharing technology platform”, material supply capability”, prediction early warning” Nanjing CDCEM, which should be emphasized strengthen findings shed light on cross-department coordination management mechanisms situations, would beneficial improving efficiency governmental
