A conservation principle applies; the objects do not disappear or disintegrate. Any object which cannot immediately pass some restriction is stored in some real or-fictitious reservo

For example, any computer controlled traffic signal system is connected with many permanently installed vehicle detectors. At any particular traffic signal (server)

We have seen that if the mean and variance rates for .(.) and .(.) depend only upon the queue length and time, then .(.) itself satisfie
