EMBEDDED LEVEL-CROSSING TECHNIQUE FOR DAMS AND QUEUES

The new concept of embedded level crossings is combined with the old principle of stationary set balance to produce an alternative approach for obtaining the steady-state distribution of the level in a dam with general release rule. The method yields the steady state distribution of the customer waiting time in the GI/G/1 queue as a special case. Results for a dam in which the instantaneous release rate is proportional to the level, and for the M/G/1, GI/M/1, E//k/M/1 and D/M/1 queues are derived, using the new technique.
