The applet requires Java 1.4.1 or higher. It will not run on Windows 95 or Mac OS 8 or 9. Mac users must have OS X 10.2.6 or higher and use a browser that supports Java 1.4. (Safari works, IE does not. Mac OS X comes with Safari. Open Safari and set it as your default web browser under Safari/Preferences/General.) On other operating systems, you may obtain the latest Java plugin from Sun's Java site.

WHAT IS IT?

This model explores "queueing theory" (waiting in lines . . .)


HOW IT WORKS

Each time step (tick), a client wanders around. When a client's wandering time gets to zero, it gets in line and waits for its turn to be served. When it gets to the front of the line, it is served for a while. When it is finished being served, it starts wandering again.

Servers do just that, serve clients.


HOW TO USE IT

Using the sliders, choose the various variables.

The Average wait time plot shows the average time clients waited in line.
