Abstract

The gray GM (1,1) prediction model and Logistic equation gray prediction model were established separately, and then the combined prediction model was established. Taking the water consumption in Ningxia Hui Autonomous Region from 2006 to 2012 as modeling data, the total water consumption of the whole region of Ningxia in 2018-2020 was analyzed and predicted. The results show that the accuracy of the three prediction models meets the accuracy requirements, but the gray GM(1,1) and combined prediction models better conform to the actual situation and have better applicability.
