Decision-making Model for Ranking Earthquake Emergency Events based on Intuitionistic Fuzzy Sets

To ravel out the difficulty in the expression and measurement of Non-subjected Information in earthquake emergency decision-making under fuzzy environmental conditions, a ranking method was put forward for earthquake emergency events on Intuitionistic Fuzzy Sets. Via the explanation about the concept of Intuitionistic Fuzzy Sets, intuitionistic fuzzy matrix and its interval estimation was established for the set of the earthquake emergency events, and the positive and negative ideal intuitionistic fuzzy earthquake emergency was determined; Through defining the distance calculation about subjected, non-subjected and hesitated degree, and respectively comparing the distance from the emergency to the positive and negative ideal event, the superiority degree model was established for the earthquake emergency events, which further gained the sequence of the emergency event collection. Case showed that model effectively solved the ranking problem about earthquake emergency events, which provided one theory and method for scientific decision-making practice in shock resistance and disaster relief.
