Disaster events can cause significant economic losses and casualties, seriouslyendanger social public security. The decision makers in the face of disaster emergencysituation, how to do make a rapid accurate and effective decision-making, the disasterto minimize the loss of government and emergency departments need to address thekey issues. The establishment of an effective decision support system, to meet thecurrent rapid emergency decision effective knowledge and information, in areasonable manner to provide the decision makers to solve this problem is the coreway. Disaster emergency decision makers are usually faced with unfamiliar to thedecision-making environment, or have plans and the insufficient knowledge ofemergency situations, in the decision-making time is limited, the fast changingenvironment and information under conditions of inadequate, relative and rationalgoblin correct judgment, practice in emergency decision makers to rely more on theircognition, experience, judgment and preference of decision making. The disasteremergency response decision support system is the major target for decision makers toprovide relevant information for decision making. To achieve this goal, this paperfocuses on the decision model of disaster emergency scenarios, informationacquisition and information recommendation and studied some key problems.This paper from the disaster emergency decision event unique decision contextualfeatures, the disaster emergency aid decision making problems, design of emergencydecision information recommendation model, gives the framework of EDIR model.The EDIR model is mainly composed of emergency information expression model,decision model and case matching model is composed of three parts, this paperdetailed design of each model of the algorithm, and gives the algorithm pseudo code,in order to facilitate the application of computer system. Finally, the simulatedexperiments, proves that EDIR model is better than the traditional CR model, disasteremergency decision-making when recommend similar historical case has a betteraccuracy.
