Homework Answers
1.
Correct Answer:
False
As per the formula of the number of customers waiting in line is infinite or undefined.
For example, if service rate = arrival rate = 5 customers per hour
Then,
number of customers waiting in line = 5/(5-5) = 5/0 or undefined

Consider the M/M/1/GD/∞/∞ queuing system where λ and μ are the arrival and server rate, respectively. Suppose customers arrive according to a rate given by λ = 12 customers per hour and that service time is exponential with a mean equal to 3 minutes. Suppose the arrival rate is increased by 20%. Determine the change in the average number of customers in the system and the average time a customer spends in the system.

In R Programming The simulation of an M/M/1 Queuing System uses the service rate of 1.0 and the arrival rate of 0.5 to find the mean waiting time as described in Section 7.8.3. You need to change the “print() statement” at line 60 on page 169 to a return statement of the mean waiting time. You can develop three independent R scripts to answer the following questions. If the arrival rate is always 0.5, draw a graph using the plot(serviceRate,...
