“This is the 2nd edition of the text book which is intended ‘for those who know queueing theory, but would like to know more about the linear algebraic approach’. On the other hand it can be used as ‘a textbook in a first course in queueing theory’ for the students who know more matrices and algebraic approach than the probability theory. Much discussion on computational aspects including matrix operations (supported by languges MATLAB, Mathematica, Maple) is presented.” (Evsen Morozov, Zentralblatt MATH, Vol. 1169, 2009)
