  • Controlled depletion of a stochastically varying resource pool
    Patent number: 8055570
    Abstract: A method for controlling resource pool depletion includes, at a first time, determining a first remainder of a depletion interval; on the basis of the first remainder, determining a first depletion rate for urging the pool to reach a selected state at the end of the depletion interval; on the basis of the first depletion rate, partially depleting the pool; and at a second time following the first time, determining a second remainder of the depletion interval; receiving state information indicative of a difference between a state of the pool at the first time and a state of the resource pool at the second time; on the basis of the second remainder and the state information, determining a second depletion rate for urging the pool to reach a selected state at the end of the depletion interval; and on the basis of the second depletion rate, partially depleting the pool.
