Queueing networks have been used to model a large variety of complex systems. However, once a realistic model has been constructed it has generally been necessary to distort and modify it so that an analytic solution could be obtained. Unfortunately, the analytic solution often has little relation to the original queueing system and consequently often produces solutions with poor accuracy. We begin with a brief introduction to the concepts of decomposition and aggregation. Application of these and other approximate methods to the analysis of computer systems are discussed by Chandy and Sauer [CHAN78].
