special municipalities in Taiwan, to analyze their water consumption from 2004 to
2014, and to apply the GM(1,1) model of the grey theory to establish water
consumption prediction models for average water consumption of the six cities as
a whole and for annual total water consumption of each city.
We analyze water consumption in Taiwan based on the statistics of tap water
consumptions from 2004 to 2014 by the publications of the Water Resources
Agency, Ministry of Economic Affairs. Combing a module of MATLAB and
EXCEL as a processing software, we deploy the GM(1,1) prediction theory to
establish prediction models and empirical analyses of tap water consumption. The
result shows as follows: First, the highest daily water consumption per capita is in
Taipei city and the highest annual total water consumption is in New Taipei city.
Second, daily water consumption per capita will continue to increase in the six
special municipalities. Third, annual water consumption per capita will also
continue to increase. Finally, The GM(1,1) prediction model has a high accuracy
rate in tap water consumption predictions.
