| Abstract: | Based on the analysis of index character of disaster evaluation, a universal formula was presented for disaster evaluation that is suitable to different disaster indexes. To different evaluation indexes and its classification standard, the parameters in formulae were optimized by using the immune evolutionary algorithms. The different disaster evaluation indexes and applicable index formula of classification standard were obtained. The formula has been used in the disaster degree evaluation of varied nature disaster in some provinces, cities and regions of China, and its evaluation result conform with the actual situation. The formulae have the peculiarities of comparison, generality, simplicity and utility. |
