Quasi-birth–death process : ウィキペディア英語版 | Quasi-birth–death process In queueing models, a discipline within the mathematical theory of probability, the quasi-birth–death process describes a generalisation of the birth–death process. As with the birth-death process it moves up and down between levels one at a time, but the time between these transitions can have a more complicated distribution encoded in the blocks. ==Discrete time==
The stochastic matrix describing the Markov chain has block structure :: where each of ''A''0, ''A''1 and ''A''2 are matrices and ''A'' *0, ''A'' *1 and ''A'' *2 are irregular matrices for the first and second levels.
