A Study on Urban Water Reuse Management Modeling

Changyu C. Zhang, K. Ponnambalam, Paul Calamai
2006 Journal of Water Management Modeling  
Uncertainty issues associated with water demand and treatment quality are modeled by introducing stochastic programming methods, namely, two-stage stochastic recourse programming and chance-constraint  ...  This thesis introduces an urban water reuse management and planning model using optimization methods with an emphasis on modeling uncertainty issues associated with water demand and water quality.  ...  As an important stochastic programming method, chance-constrained programming offers a comprehensive strategy in modeling quality compliance in water reuse system based on various risk levels.  ...
