Disasters are different from the usual predicted objects, thus special attention should be pay to its predicted precision. But at present, the grey disaster prediction values aren't accurate sufficiently except for one or two data with higher accuracy near the prediction original point. This paper puts forward the concept of associate grey information and establishes the associate grey disaster prediction model. Finally, it is proved that the associate grey disaster prediction model can improve predicted precision....
