Abstract

This paper develops a Gray-Markov model-based approach to predict the municipals water use by combining the grey system theory and Markov random process theory. The proposed approach uses the prediction curve of the grey dynamic forecast model GM(1, 1) as the datum line of the trend of the city water use. Besides, the Markov prediction approach is applied to determine the range of the system chance fluctuation, optimize and modify the grey predictive value. To demonstrate that our system is working correctly, the author used the prediction system to analyze the water data and predict the volume of water use in the city of Zhuhai at a specific time. The approach can not only effectively discover the overall trend of the city water use, but also overcome the influence of the chance fluctuation upon the precision of prediction. Therefore, the approach is effective in real world.
