\begin{equation}\label{a}  a = W_s \cdot \lambda = \frac{\lambda}{\mu}  \end{equation}  Given a limited numbers The second dimensionless parameter of this problem is the ratio between the traffic intensity and the number  of servers $c$, i. e.  the \textbf{average server utilization} $\rho$ is: $\rho$:  \begin{equation}  \rho = \frac{a}{c} = \frac{\lambda}{\mu \cdot c}  \end{equation}
