Inexact Optimization Model for Supporting Waste-Load Allocation in the Xiangxi River Basin of the Three Gorges Reservoir Region, China

In this study, a large-scale inexact two-stage waste-load allocation (ITS-WLA) model is developed to identify desired decision alternatives for supporting economic development and water quality management. In this model, uncertainties expressed as both probability distributions and discrete intervals are incorporated within a general optimization framework. A two-step interactive solution algorithm is used to generate interval solutions, and …
