    Use of multi-objective particle swarm optimization in water resources management
    (Colorado State University. Libraries, 2007) Baltar, Alexandre Moreira, author; Fontane, Darrell G., advisor
    Water resources management presents a large variety of multi-objective problems that require powerful optimization tools to fully characterize the existing trade-offs. Different optimization methods, based on mathematical programming at first and on evolutionary algorithms (EA) more recently, have been applied with various degrees of success. This dissertation presents a multi-objective implementation of a relatively recent evolutionary technique called particle swarm optimization (PSO). The multi-objective PSO (MOPSO) algorithm was implemented as a generalized solver for Microsoft Excel®, and applied to a set of test functions commonly used in the EA literature and to selected water resources management problems, including a classic multi-purpose reservoir operation problem, a problem of selective withdrawal from thermally stratified reservoirs, and a reservoir operation problem using storage guide curves with fuzzy objectives.
