D-DEMATEL: A new method to identify critical success factors in emergency management
Due to the variety and destructiveness of disasters, management has emerged as a world theme and attracted more and more public attention. A large quantity of research on optimizing the management has been done while still has improvement space. In this paper, a new method called D-DEMATEL which combines D number theory and decision-making and laboratory (DEMATEL) to identify the critical success factors (CSFs) in is proposed. Firstly, multiple experts evaluate the direct relations of influential factors in respectively from positive and negative side. The results are presented as intuitionistic fuzzy numbers (IFNs). Secondly, convert the IFNs into D numbers and use the combination rule of D numbers to fuse group opinions. Thirdly, based on DEMATEL, the cause-effect classification of factors can be obtained. Finally, the factors in cause category are identified as CSFs in emergency management. Based on the proposed method, the optimization of emergency management can be efficiently simplified into optimizing the identified CSFs. The proposed method is well addressed the fuzziness and subjectivity in linguistic . Hence, the proposed method is well applicable to identify the CSFs in emergency management which inherently has a linguistic process.

Quantitative modelling
Identified CSF in management (in order of importance):•F2 - reasonable organizational structure and clear awareness of responsibilities•F9 - clear procedure of reporting and submitting information•F6 - government unity of leadership to plan and coordinate as a whole•F10 - application of modern logistics technology•F5 - regular organization of simulated •F4 - education campaign on and
Authors describe the way to combine different theories through following their technical research step by step. However, someone who understands the formulas of these theories should read the article for further information.
Procedure of identifying CSFs in management based on D-DEMATEL:Expert on the direct relations of influential factors in researching systemFuse group opinions based on D number theoryUse DEMATEL to identify the CSFs
Based on D number theory and decision-making and laboratory (DEMATEL), a new method called D-DEMATEL to identify critical success factors (CSFs) in management is proposed
Compared with fuzzy DEMATEL and evidential DEMATEL, D-DEMATEL is well addressed the fuzziness and subjectivity in linguistic and more applicable to identify the CSFs in management, which inherently has a linguistic process.
Compared with the existing methods, D-DEMATEL has ability to obtain the total relations of influential factors and identify the CSFs in management.The optimization of these CSFs can promote the overall welfare of management.
