Hi   All Its a very good simulator   for M/M/1. It brings t he power of Discrete Event Simulation and Web technologies for teaching and learning Queuing Theory and Queuing Networks.     Complex networks of M/M/1 queues can be modeled and simulated easily with this web-based simulator. The simulator runs a complete discrete event simulation to generate the statistics of queues and systems. http://www.simjs.com/queuing/
