| Abstract: | In this peper, the inequality time-distance in reality obovation had beentransformed. The equality time-distance GM (1, 1) model was transformed into inequatily time-distance GM (1 ,1) model to predict, and predicted accuracy was improred by residue correct. |

| Keywords: | inequality time- distance grey model settlement prediction residue correct |
