Operator-Geometric Stationary Distributions for Markov Chains, with Application to Queueing Models.
Abstract
This paper considers a class of Markov chains on a bivariate state space (N,E), whose transition probabilities have a particular 'block-partitioned' structure. Examples of such chains include those studied by Neuts (1978) who took E to be finite: they also include chains studied in queueing theory, such as (Nn, Sn) where Nn is the number of customers in a GI/G/1 queue immediately before, and Sn the remaining service time immediately after, the nth arrival. We show that the stationary distribution for these chains has an 'operator-geometric' nature where the operator S is the mininal solution of a non-linear operator equation. Necessary and sufficient conditions for Pi to exist are also found. In the case of the GI/G/1 queueing chain above these are exactly the usual stability conditions.
