Abstract: Many authors have documented the minimal use
of optimization in practical day to day multipurpose reservoir operations.
The RiverWare decision support system RiverWare 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, pre-emptive 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.
