Answer #1

The forumlae being used is as follows,

Server utilisation (p) = W/u*M Waiting time in queue Wq = 1/M*u- Waiting time in system Ws = Wq + 1/u

Excel formulation is as follows,

Excel Formulation: А B C D E F G H N 2 3 4 Scenario 1: 3 clerks Average time for customer arrival average service time 1.5 Sc

Excel Solution:

Excel Solution: B с E F G H 1 2 3 Scenario 1: 3 clerks Average time for customer arrival average service time Scenario 2: 4 c

i. Average time customer has to wait, with 3 clerks is 6 min.
