Homogeneous M/M/r systems, the classical model<br />

This section presents the classical queuing theory approach to solving a<br />

machine interference problem. It should be noted that this system is analyzed<br />

by many authors in different books. It is a classical example for queueing<br />

systems with state-dependent arrival rates <strong>and</strong> it can be treated in the<br />

framework of the so-called birth-<strong>and</strong>-death processes. The present problem is<br />

descibed in several classical books on queueing systems, for example<br />

[2, 12, 15, 41, 29, 33, 79] suct to mention the basic ones. Our aim is to show<br />

the form of the steady-state probabilities of stopped machines. In the above<br />

mentioned works one can find the detailed analysis of waiting time, down<br />

time distibution of machines, too. Several numerical examples from real life<br />

situations illustrates this interesting system.<br />

It is also proved that in steady-state the arriving machines’s distribution in<br />

system containing N machines is the same as the outside observer’s<br />
