JMVA is the GUI front-end to JMT analytic engine. It allows the solution of open, closed or mixed queuing networks with the exact or approximate MVA algorithm with single or multiple customer classes. Service centres can be of three types:

1. Load Independent
2. Load Dependent (currently supported only in single-class closed models)
3. Delay

JMVA allows the automated execution of What-if analysis i.e. different models are evaluated by changing a defined control parameter.
Model definition is guided with a wizard interface. Optionally, created model can be solved with simulator by importing it into JSIM.
