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> http://mathoverflow.net/questions/127498/quantum-uncertainty-can-explain-the-riemann-hypothesis Comment by 2013-04-14T01:45:56Z 2013-04-14T01:45:56Z Not a real question?
