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 8
(Atlantic Video) Atlantic Video, a small video rental store in Philadelphia, is open 24 hours a
day, and—due to its proximity to a major business school—experiences customers arriving
around the clock. A recent analysis done by the store manager indicates that there are 30
customers arriving every hour, with a standard deviation of interarrival times of 2 minutes. This
arrival pattern is consistent and is independent of the time of day. The checkout is currently
operated by one employee, who needs on average 1.7 minutes to check out a customer. The
standard deviation of this check-out time is 3 minutes, primarily as a result of customers taking
home different numbers of videos.
a. If you assume that every customer rents at least one video (i.e., has to go to the
checkout), what is the average time a customer has to wait in line before getting served
by the checkout employee, not including the actual checkout time (within 1 minute)?
b. If there are no customers requiring…

- 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…arrow_forwardQuestion : 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. True or Falsearrow_forwardQuestion 4 A petrol station in the capital Kingstown has a single pump manned by one attendant. Vehicles arrive at the rate of 20 customers per hour and petrol filling takes 2 minutes on an average. Assume the arrival rate is Poisson probability distribution and service rate is exponentially distributed. Arrivals tend to follow a Poisson distribution, and service times tend to be exponential. The attendant is paid $10 per hour, but because of lost goodwill and sales, station loses about $15 per hour of customer time spent waiting for the attendant to service and order. Part A Answer the following questions based on single channel model: a. What is the probability that no customers are in the system (Po)?! b.

- QUESTION 1 A multiple channel queuing system with a Poisson arrival rate, and an exponential service time distribution has an average arrival rate of 2.5 customers per hour and an average service time of eighty minutes per customer.

For the system just described, what is the minimum number of servers required to retain stability i.e., to avoid overloading? A. 3 B. 2 C. 4 D. 1 QUESTION 2 Customers arrive at the lone check-out desk of a certain convenience store at the average rate of 0.23 per minute.

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. The manager of the DMV would like you to calculate the operational characteristics of the waiting line system. (a) What is the average system utilization? (b) What is the average number of customers in the system? (c) What is the average number of customers waiting in line?…arrow_forwardQuestion 40 of 50 Francesca is helping a customer troubleshoot a software program and determines the customer needs to update their software. What is the best way to communicate this to avoid making the customer feel defensive? "You haven't kept your software updated, which is why it isn't working. Do you know how to run an update? If not, I can walk you through the steps." "I think that your software isn't working because you haven't run an update lately. May I walk you through the steps?" "A lot of customers don't know how to run a software update, but I can walk you through the steps." "I think we can solve the issue by updating your software.
