New Fuzzy Classified Model for Disaster Loss

Abstract:

The quantitative assessment and classification of the disaster loss is a complex and difficult work. It often encounters the problem that different people will arbitrarily create different membership functions for the same issue, so the results of different model can not be compared. The other problem for the current classified models of the loss of disaster is that the evaluation factors may have mutual relationships between each other, which will affect the results. In the aim of solving these problems, a new model for fuzzy classification for the loss of disaster is proposed. Firstly, the related indexes are decomposed based on orthogonalization theory in order to solve mutual relations between the factors of loss. And then, in term of fuzzy and probabilistic reasoning theory, the fuzzy membership interval function of loss of disaster is obtained through establishing optimization model. Through solving the optimization model by Genetic algorithms, the fuzzy classified model is established. Finally, the model proposed is utilized to evaluate the loss of mud-rock flow in Bijie area Guizhou province. The conclusion shows that model proposed has highly precision to evaluate the loss of disaster.
