Evaluation of emergency risk management capability based on hesitant fuzzy Einstein operator

Abstract

Scientific and objective evaluation of emergency risk management capability is of vital importance to the improvement of emergency management system. A three-perspective evaluation system of emergency risk management capability is proposed, which includes the risk identification, risk reduction, an d risk treatment. Considering the hesitation of people’s judgment about complex situations, a new fuzzy comprehensive evaluation model based on hesitant fuzzy Einstein hybrid geometric operator is developed. Finally, a practical example is given to verify the developed approaches and to demonstrate its practicality and effectiveness.
