Real-time optimization

Real-time optimization problems rely on decision rules that specify how decisions should
maximize future benefit, given the current state of a system. State dependence provides a
convenient way to deal with uncertainty. Some examples:

Reservoir releases Decision rule specifies how current release should depend on current
storage. Primary uncertainty is future reservoir inflow.

Water treatment Decision rule specifies how current operating conditions (e.g. temperature
or chemical inputs) should depend on current concentration in treatment tank. Primary
uncertainty is future influent concentration.

Irrigation management - Decision rule specifies how current applied irrigation water should
depend on current soil moisture and temperature. Primary uncertainties are future
meteorological variables
