Implementing and optimizing a structured decision making model for regulated rivers

Duration

July 2013 - December 2014

Narrative

In a recently-completed project, a structured decison making model was developed for the operation of Tims Ford Dam on the Elk River. In this follow-up project, we are:

1. Initiating training and support for TVA and USFWS personnel to improve their understanding of how the decision model works, how to use it, and how to update it.

2. Investigating options for proceeding with optimization of the decision model. Optimization is a complex component of the Structured Decision Making process that, although not required to effectively use existing, fully-parameterized decision models, helps managers identify long-term optimal decisions. Optimization is a rapidly-changing area of research in the decision-making world. Colin has limited experience with optimization, but has discussed the topic with colleagues more familiar with the process. Identifying the best method for optimization (there are many) and conducting optimization analyses would require a year or more of additional work. However, even if optimization cannot be accomplished during six additional months of support, it would be useful to begin this process.
