Question 8.1
The computer lab at State University has a help desk to assist students working on computer
spreadsheet assignments. The students patiently form a single line in front of the desk to wait for help.
Students are served based on a first-come, first-served priority rule. Students arrive at the help desk at
the rate of 4 every 10 minutes. The average service time is 2 minutes. The Poisson distribution is
appropriate for the arrival rate and service times are exponentially distributed.
QUESTION #4
Four delivery trucks are in a queue at a Tool Company with
only one service bay. The trucks are identified by the sequence
in which they arrived at the Company. Assume the time is
10:00 a.m. The table shows the times necessary to unload each
vehicle and the periods when the commodities they contain
are expected in the factory.
Determine the schedules that result for each of the rules SPE,
CR EDD, and FSFC. In each case compute the average tardiness,
the number of tardy jobs, and mean flow time.

QUESTION 5
Regional Airlines is establishing a new telephone system for handling flight reservations. During the 10:00 AM to 2:00 PM time period,
calls to the reservation agent occur randomly at an average rate of one call every 3.75 minutes. Historical service time data show that a
reservation agent spends an average of 3 minutes with each customer. The waiting line model assumptions of Poisson arrivals and
exponential service times appear reasonable for the telephone reservation system.
At a planning meeting, Regional's management team agreed that an acceptable customer service goal is to answer at least 75% of the
incoming calls immediately. During the planning meeting, Regional's vice president of administration pointed out that the data show that
the average service rate for an agent is faster than the average arrival rate of the telephone calls. The vice president's conclusion was
that personnel costs could be minimized by using one agent and that single agent must be able to…

- Question : One way for a manager of a property to increase the net operating income of a retail store is to increase the flow of customer traffic into the store. If the increased traffic results in increased sales, then the net operating income of the store will increase. If this can be sustained then the manager has increased the value of the property.

The average time for a customer to get service is 4 minutes and this time is exponentially distributed. What would be the average waiting time of a customer in the system? b. Consider the previous problem once again. Arrivals to single bank counter are Poisson distributed with a rate of 22 per hour. The time for a customer to get service, however, is constant at 4 minutes.

The dealer can buy the painting today for $40,000 or can wait a day and buy the painting tomorrow (if it has not been sold) for $30,000. The dealer may also wait another day and buy the painting (if it is still available) for $26,000. At the end of the third day, the painting will no longer be available for sale. Each day, there is a 0.60 probability that the painting will be sold.

Currently, the DMV uses a single-server, single-line, single-phase system when processing license renewals. Based on historical evidence, the average number of customers arriving per hour is 12 and is described by a Poisson distribution. The service rate is 18 customers per hour with the service times following an exponential distribution. The customers are patient and come from an infinite population.

Arival rate of customers is 26 per hour Poisson and average service time is 6 minutes exponential. The arriving customers can be served in three ways. The first way is to open two separate counters for the two types of foods. The second way is to pool the services, and offer both types of foods in both the counters. The third way is to open a large number (0) of self-service counters for the customers. Which way will lead to the maximum busy period of the system? wwmarrow_forwardQuestion related to queing theory don't copy A bank has two tellers working on savings accounts. The first teller handles withdrawals only while the second teller handles depositors only. It has been found that the service time distributions of both depositors and withdrawals are exponential with a mean service time of 5 minutes per customer. Depositors and withdrawers are found to arrive in a Poisson distribution throughout the day with mean arrival rate of 12 and eight per hour, respectively. What would be the effect on the average waiting time for depositors and withdrawers if each teller could handle both withdrawals and depositors? What would be the effect if this could only be accomplished by increasing the service time to four minutes?arrow_forward
