9. In a simple queuing situation, the following formulae may be used to some of the system parameters:

You have observed a queuing system for several days and one sequence of observations had the results as shown:

Now,

(a) Calculate the four system parameters quoted above by a simulation of the system using the given data;

(b) Calculate the four system parameters using the formulae; and comment on the value obtained in

(a) and

(b) and the use of the simulation technique.

where average queuing time = u(u - ) average system process time (or time in the system)=1/( -) average number in the queue (including zeros) = /(u - ) average number in the system = 1/(-) = mean (average) rate of arrivals mean (average) rate of service
