Abstract:
Objective In order to analyse the problem that eligible water from factory will deteriorate during the transportation in the water supply networks. The aim of the present paper is to provide theoretic basis to ameliorate the water quality and make drinking water more secure. Methods Regarding water supply networks as a grey system, applying grey relational analysis to establish the attribution recognition model. The classification of water quality was treated as a grey sort and the state of water quality was a grey system. Water quality classified rank was determined and the water quality was analyzed according to the grey relation analysis theory. Results Three monitoring spots in north networks which included fourteen water quality gene was calculated. The relation degree matrix was educed. The result showed that the water quality of the first and the third monitoring spots belonged to grade one, and the second spot belonged to grade two. Conclusion Applying attribute recognition model based on the grey relation to analyze the water quality in the water supply networks, the case study shows that the grey relational analysis method is more reasonable, simple, reliable and informative. The effect of subjective factors is eliminated. The accuracy of model is verified by the experimental data in the end. There is a good agreement between the calculated result and actual condition.
