Title: Many Objective Robust Decision Making for Environmental and Water Systems Under Uncertainty

Abstract:

Environmental and water resources systems are undergoing pressures that are difficult to quantify, such as 
population growth, socioeconomic changes, and climate change.  Recently, a class of methods termed "bottom-up" 
decision making have advanced techniques for generating and evaluating systems' performance under these types of 
uncertainty.  In this presentation, I will provide a review of the different bottom-up decision making methods and 
then I will provide an example of one technique: Many Objective Robust Decision Making (MORDM).  MORDM combines 
multi-objective evolutionary algorithms with uncertainty analysis techniques and interactive visualizations.  I will 
show a MORDM example in the Lower Rio Grande Valley of Texas, and I will also present recent work that shows how 
MORDM can generate new scenarios to inform decision making.  Examples of other problems that could also be benefited 
by MORDM, such as improving drinking water quality, will also be provided.
