The structure of a simple two station Markovian tandem queue is as follows: tasks arrive at a buffer with zero, finite or infinite capacity, in front of the first station according to a Poisson process. Zero capacity means that no task may wait or it will be lost from the system. The tasks are served, in the order of their arrival, by a single server facility with exponential distribution. They then proceed to a buffer at the second station where they are similarly served. Computer system models provide detailed answer to system performance. In this paper a two stage tandem network system with blocking and feedback is considered and it performance has been analyzed by spectral expansion method.
