Quasi-birth-death process

From Wikipedia, the free encyclopedia

In queueing models, the quasi-birth-death process describes a generlisation of the birth-death process. As with the birth-death process movements between it moves skip free up and down, but unlike the birth-death process the process is semi-Markov process rather than a Markov process.
