QNAT: a graphical tool for the analysis of queueing networks

The Queueing Network Analysis Tool (QNAT) is a powerful package for analysing a wide variety of queueing networks. QNAT has a friendly GUI for a PC-Windows environment and uses Mathematica/sup TM/ as its computing platform. QNAT can handle general configurations of open and closed networks of both finite and infinite capacity queues. Incorporation of fork-join nodes (with and without a synchronising queue), multiclass customers, mixed customer classes and blocking mechanisms of different types are some of the other features available in QNAT.
