Can you suggest a mathematical model for a cluster of web servers?

Question

Clustering

Can you tell me where you can find a sane mathematical model for a cluster of web servers. I so understand here it is necessary to think up something with the theory of queues?
In extreme cases, advise a web resource where you can ask a question of this kind (except for math.stackexchange.com, perhaps).
Thanks in advance to the mathematically savvy part of the audience for the succinct answers!

Answer 1

Google for "Mathematical model and algorithm of quality management in cluster systems for collecting and processing information". I think this is what you need.
