Abstract: Real-time data of emergencies are the basis of emergency decision making. Better capacity of data handling, exacting entropy weights of emergency attributes, and filtering critical attributes which reflect the development trend of emergencies are keys to improving efficiency and accuracy of decision making. First, this paper shows a way that uses common knowledge model to structurally represent emergency and its attributes. Then the monitoring data of emergency attributes are converted to interval numbers with the method of interval multi-attribute decision making referred. Consequently, dimension of the data decreases while this way keeps temporal order information. Besides, the emergency attributes are transformed into cost-type attributes by means of defining the distance of data and interval, and entropy weights of emergency attributes are calculated by utilizing the method of interval multi-attribute decision-making based on entropy weight. The higher the entropy weight, the more the information which contains the trend of emergency, and this kind of attributes is more important. Finally, an example is given to illustrate effectiveness and practicality of the method.
