lambda $=2$; $\%$ Arrival rate: $2$ calls per minute

mu $=0\mathrm{.}1$; $\%$ Service rate: $0\mathrm{.}1$ calls per minute per agent

$\%$ Assuming an initial number of agents for the calculation

c $=4$; $\%$ Placeholder, needs adjustment based on system requirements

$\%$ Nwait $=$ Nwait Maximum number of customers waiting in the queue. P

$\%$ Nwait is maximum queue length.

Nwait $=$ lambda $/($mu $-$ lambda$)$;

$\%$ Calculate System Capacity$($N$)=$ c $+$ Queue Length

N $=$ c $+$ Nwait;
