Optimization of Urban Water Supply Schemes based on Grey System Theory

Urban water supply schemes are studied with multi-attribute characteristics taken into consideration. This paper proposes an optimized urban water supply scheme based on grey system theory. In the model, optimized indicators are given and their weights are acquired through optimized grey related analysis. These indicators are subject to standardization and are calculated to get grey incidence degree. The optimal water supply scheme is determined by the grey incidence degree. Finally, empirical test on the water supply scheme of a city is conducted to prove its objectivity, feasibility and reliability.
