Abstract/Summary:
Through the early cities of research to understand the current checking method of the water demand are mainly the quota method and historical water consumption forecasting method.The checking method of the water demand as the research object, selected part of industry and hotels, through their main influencing factors on water consumption analysis,finding out the relevant indicators can be approved before trying to put forward effective the checking method of the demand.In view of the current part of the city’s water demand with three years of history of water on average prediction method,in the research,three water forecast method are proposed:moving average method,exponential smoothing and gray prediction method.Through calculation examples, the precision of grey prediction method is the best,followed by moving average method,but if we consider the method is simple in calculation and guarantee the prediction accuracy is good, moving weighted average method effect is best.In addition, the main on the part of the industry were influence of water analysis,and find out the related clustering index of water use.In the selection of industrial water use clustering index, we can use the index of recycling rate, indirect cooling water circulation rate and boiler cooling water recovery rate. In the selection of the hotel water clustering index,we can be used in the hotel star, water-saving apparatus and occupancy rate and other indicators.According to these indicators of water collected relative data in user level,combined with the current hot field of big data clustering algorithm,using SPSS version 19.0 K-means cluster analysis module can be found in the same industry in category unreasonable water use of users.Therefore,if approved methods only consider the relevant data analysis without considering management method,then the use of combination of water prediction and clustering analysis method,can help manage who water planning issued as a good reference.
