Homework Answers
a)
Average Waiting Time = Number of Entities in System/Arrival Rate
Average Waiting time = 5/3 = 1.6667 Hours
c)
Average Number of Entities in queue = Average Number of Entities in system - (Arrival Rate/Service Rate)
Average Number of Entities in queue = 5 - (3/5)
Average Number of Entities in queue = 5 - 0.6
Average Number of Entities in queue = 4.4 ~ 5 entities
b)
Average Waiting time in queue = Average Number of Entities in queue/Arrival Rate
Average Waiting time in queue = 4.4/3 = 1.46667 Hours

Consider the following parameters for a queueing system with an infinite queue and infinite calling population. Arrivals follow the Poisson distribution with an average rate of 12 per hour. Service times are exponentially distributed with an average time of 4 minutes. Find the set of queue statistics (N, Nq, T, Tq, r), and find the percentage of time that the server is busy.

QUESTION 2:
Consider a check–out station at a small store with customer
arrivals described by a Poisson process with intensity ? = 10
customers per hour. There are two service team members, Tom and
Jerry, working one per shift. In Tom’s shift, the service times are
exponentially distributed with the mean time equal to 3 minutes,
while for Jerry service times are exponentially distributed with
the mean time equal to 5 minutes.

Question 1 Simulate the operation of a first-in-first-out queuing system until time TE = 30 minutes, using the interarrival and service-times given below (in minutes) in the given order. Interarrival times: 4, 3, 1, 1, 5, 7, 10 Service times: 4, 4, 6, 9, 8, 7, 4, 6 Given that the first arrival occurs at time t = 0, create a record of hand simulation (on the table given in the last page) using the event-scheduling algorithm and compute the...

answer the question number 3 as stated in the picture
2. Vehicles arrive at an entrance to a recreational park. There is a single gate at which all vehicles must stop), where a park attendant distributes a free brochure. The park opens at 08:00 am, at which time vehicles begin to arrive at a rate of 480 veh/hr. after 20 minutes the arrival flow rate declines at 120 veh/hr, and it continues at that level for the remainder of the...
