<p>Hi, I'm beginning to learn queue theory and I have a question. I want try use the queue theory to estimate the indicated server amount to handle operations in a queue. My big problem is that the classical equations for the M/M/C system that I using return "expected" values only to a minimal server range.</p> <p>For example: If I use $\lambda=15$, $\mu=1$ and $c=10$ in the site <a href="http://www.supositorio.com/rcalc/rcalclite.htm" rel="nofollow">http://www.supositorio.com/rcalc/rcalclite.htm</a>, it give me a error, because $c\cdot\mu &lt; \lambda$. But, if I use the site <a href="http://www.stat.auckland.ac.nz/~stats255/qsim/qsim.html" rel="nofollow">http://www.stat.auckland.ac.nz/~stats255/qsim/qsim.html</a> I can make this evaluation, it give me $W = 19.257$.</p> <p>My equations implementations give me the same results of the first site, but, I need a implementation that give me results equals from second site. Anybody know if this second site implementation is correct from the queue theory perspective? Where I can find the equations that implements this second approach?</p> <p>Thanks by help!</p>

Not a real question? Ok!

It's very recent, do you already knew it?

I understand this, you understand what?

To use the Gram-Schmidt process I need four vectors to build four new orthogonal vectors, or not?
