| Researchers are increasingly using multiobjective evolutionary algorithms (MOEAs) to optimize water management problems with conflicting performance objectives. Often the applications consider far-reaching policy options or designs, such as building new reservoirs, and use simplified representations of systems to evaluate their performance. This study contributes a many-objective analysis of water supply in the Tarrant Regional Water District (TRWD) in Texas, USA, in order to demonstrate how MOEA decision support can be used with complex simulation models in a highly constrained water planning environment. A detailed RiverWare representation of TRWD’s system is coupled with the Borg MOEA to solve a seven objective problem formulation. Objectives within the formulation include system-wide performance objectives as well as reliability objectives to balance multiple reservoirs, calculated using two stochastic hydrology scenarios. Results provide valuable information to TRWD that may inform the utility’s approach to optimization and decision making in the future as well as illuminate the benefits of optimizing system-wide and component-specific objectives to reveal hidden system dynamics. |
