Departure Processes of a Tandem Network

摘要：

Consider a 2-stage single-server tandem queue with a MAP to the first stage and the exponential service times. Using the DREB scheme, we formulate the joint queue length process into a single-dimensional level-dependent quasi-birth-death (LDQBD) process with expanding blocks.This allows us to show that the departure process from stage 1 is a MAP with infinite phases or IMAP and that the departure process of any IMAP/M/1 is still an IMAP.
