During the early morning hours, customers arrive at a branch post office at an average rate of 45 per hour (Poisson), while clerks can handle transactions in an average time (exponential) of 4 minutes each.

Fill in the following information:

Lq = Avg Number in Line

Wq = Avg Time in Line

Ws = Avg Time in System

For M = 7:

Lq = 0.028

Wq = 0.0006 Hours

Wq = 0.0373 Minutes

Ws = 4.0373 Minutes

For M = 6:

Lq =

Wq = Hours

Wq = 0.132 Minutes

Ws = Minutes

For M = 5:

Lq =

Wq = 0.00787 Hours

Wq = Minutes

Ws = 4.472 Minutes

For M = 4

Lq =

Wq = 0.03396 Hours

Wq = Minutes

Ws = Minutes

Format your answers as x.xxx

The minimum number of clerks needed to keep the average time in the system to under 5 minutes =

A small branch bank has two tellers, one for deposits and one for withdrawals. Customers arrive at each teller’s window with an average rate of 18 customers per hour. (The total customer arrival rate is 36 per hour.) The interarrival times are exponential. The service time of each teller is exponential with a mean of 3 minutes. The bank manager is considering changing the setup to allow each teller to handle both withdrawals and deposits to avoid the situations that...
