Multiple-Objective Stochastic Waste-Load Allocation


The practice of waste-load allocation in water quality management involves several noncommensurate and conflicting objectives. In particular, the objectives considered in this multiobjective stochastic waste-load allocation study are (1) maximization of total waste discharge, (2) maximization of instream dissolved oxygen concentration, (3) minimization of difference in equity measures, and (4) maximization of reliability of water quality compliance. To demonstrate the analysis, the model was applied to an example involving six waste dischargers.

Keywords. Waste-load allocation, water-quality management, multiple-objective analysis, optimization, uncertainty analysis.
