| Abstract: | In this paper, the method of fuzzy multistep decision-making has been applied to earthquake prediction countermeasures.The mathematical model of the fuzzy multistep decision-making applied to earthquake prediction was presented first.Since there is a long way, to go from earthquake prediction to its practical use, we have to take decisions and countermeasures at every moment from discovering any anomaly of precursors up to their peak. Fuzzy multistep decision-making may take an important part in the process of decision-making.It can help the decision-making department make a reasonable response based on the variations of input precursors and go forward to obtain the optimum social benefit. Secondly, two practical examples of fuzzy multistep decision-making in earthquake prediction were given. One is an numerical example.Another is a discussion on the fuzzy decision-making in the prediction of 1976 M=7.2 Songpan earthquake. |
