From the point of co-occurrence analysis, the article uses theme search to identify a collection of emergencies, which selected from about 70 years of research literature in China Journal full-text database and Web of Science database between 1959 and 2012. Through analysing the frequency of emergencies, the article builds a co-occurrence matrix, creates an emergency network according to co-occurrence rate between emergencies, and identifies a number of hidden disaster chains within the emergency network model. Secondly, losses occur due to the intervention of decision markers, and the feeling of psychological and the weight of possible scenarios are described using the theory of prospect. According to the values, weights and alternative costs, the overall prospect value of each alternative is calculated to determine the rank of schemes. Finally, the analogy simulation is given to illustrate the feasibility and validity of the emergency network and the proposed method.
