Abstract: Many authors have documented the minimal use of optimization
in practical day-to-day multipurpose reservoir operations. The RiverWare
decision support system is a flexible general river basin modeling tool
that allows water resources engineers to both simulate and optimize the
management of multipurpose reservoir systems for daily operations. This
paper describes RiverWare's optimization capabilities and its use by Tennessee
Valley Authority operations schedulers. Input data requirements include
(1) physical and economic characteristics of the system; (2) prioritized
policy goals; and (3) parameters for automatic linearization. RiverWare
automatically generates and efficiently solves a multiobjective, preemptive
linear goal programming formulation of a reservoir system. An advanced
feature of RiverWare is that both the physical model of the river basin
and the operating policy are defined and easily modified by the modeler
through an interactive graphical user interface. Any modifications are
automatically incorporated into the linear preemptive goal program. RiverWare's
combination of detailed system representation, policy expression flexibility,
and computational speed make it suitable for use in routine daily scheduling
of large complex multiobjective reservoir systems.
