Queueing networks with batch service

In this paper, the decomposition method for ordinary single class open queueing networks is extended to queueing networks with batch processing. A comparison study with discrete event simulation as benchmark shows that the approach provides fairly good results for a wide range of applications. The model has been integrated into a software system for analysing large scale semiconductor manufacturing systems. [Received: 08 June 2009; Revised: 23 November 2009; Accepted: 01 February 2010]
