Exact recursive formulas are derived for the state probabilities in priority queueing systems (preemptive and non-preemptive). The derivation is based only on the general structure of the generating function involved, and thus is simpler and more general than previous methods. Furthermore, applications of the method to other queueing systems are discussed.
