Single Server Simulation Use ARENA to develop a single server simulation model where customers arrive to a check$-$out counter at the store with Lambda $=12$Customer$/$hr and served with Mu $=15$ Customer$/$hr$.$ Both inter$-$arrival and service times are exponentially distributed.

The management uses these five performance measures for the counter:

$-$ Avg. waiting time $($Wq$)$

$-$ Avg. time in system $($W$)$

$-$ Avg. number of customers in queue $($Lq$)$

$-$ Avg. number of customers in system $($L$)$

$-$ Server utilization $($U$)$Queuing Model $($M$/$M$/1)$ Formulas:
