Chapter 1, Problem 7PA
Four regional less-than-truckload (LTL) carriers handle shipments traveling from Lexington, Kentucky, to Springfield, Illinois. All four companies say that their normal service time to deliver these shipments is two business days. The four carriers compete with each other on the basis of price and service quality rating, as shown in the following table. The price reported in the table is the (nondiscounted) cost per hundredweight (cwt) of sending a 600- pound shipment from Lexington to Springfield at freight class 70. The service quality rating measures a carrier’s loss and damage record and goes from 0 (poor quality) to 100 (high quality).
Which of these LTL carriers are on the efficient frontier?

Telephone poles, once installed in a location, remain in useful service until one of a variety of events occur. (a) Name three reasons why a telephone pole might be removed from useful service at a particular location. (b) You are to estimate the total useful life of telephone poles. If the pole is removed from an original location while it is still serviceable, it will be installed elsewhere. Estimate the optimistic life, most likely life, and pessimistic life for telephone poles. What percentage of all telephone poles would you expect to have a total useful life greater than your estimated optimistic life? (c) What is an environmental life cycle assessment (LCA)? How do treated wood, metal, and concrete poles compare?

- During nearly four decades of business operations, Memphis-based FedEx has earned a reputation for reliable, on-time delivery of packages to homes and offices around the country. Founder Fred Smith originally focused on overnight deliveries, choosing Memphis as the company’s headquarters because the airport rarely closes due to bad weather. With FedEx’s planes departing and arriving on schedule nearly all the time, its express shipments usually remained on schedule, then and now. To reassure customers that delivery will take place when and where promised, the firm offers a money-back guarantee on time-sensitive express shipments, among other services. FedEx has steadily expanded its portfolio of services since the 1970s. Its original overnight express delivery is currently available to U.S. customers in various forms, including “first-overnight” delivery, next-morning delivery, next-afternoon delivery, and budget-pleasing two- or three-day delivery. The company’s services also include cost-effective ground delivery for parcels and extra-speedy same-day delivery for urgent deliveries within 1,800 cities. Over the years, FedEx has widened its delivery network to more than 220 countries. It has purchased more cargo jets and acquired specialized shipping firms, including Tiger International, Roberts Express, RPS, and TNT Express, to support global growth. For international business customers needing products, parts, or raw materials shipped across countries or continents, the company now offers time-saving services such as commercial freight forwarding and cross-border logistical support. To add the convenience of local drop-off and pickup points for U.S. consumers and small businesses, FedEx acquired the Kinko’s office services company in 2004 and later rebranded it as FedEx Office. This acquisition also added printing and copying to the menu of services offered. Then the company arranged for large U.S. retailers such as Walgreens, Albertsons, Kroger, and Safeway to accept packages for shipment and receive package delivery for customer pickup in thousands of store locations. This means people who want to send a package can head to a nearby retailer and ship where they shop, rather than making a separate trip to the FedEx location. It’s also a safe alternative for packages to be picked up by people who don’t want FedEx shipments left by the front door. Another service FedEx offers to small and mid-sized businesses, including retailers, is FedEx Fulfillment. The purpose is to expedite order fulfillment by having each business store its products in a FedEx warehouse. Then, when the business’s customers place orders, FedEx puts the products into boxes bearing the business’s own logo and ships directly to those customers. The business doesn’t need a separate warehouse or staff for fulfillment, and packages are on their way to customers more quickly because the products were in FedEx’s warehouse, ready to be packed and shipped. This service puts FedEx into direct competition with Amazon.com, which offers a similar service to merchants that sell through the online Amazon Marketplace. But it also gives businesses that don’t sell via Amazon a fast and professional fulfillment alternative. FedEx is careful to let customers know, through media and social-media announcements, when it anticipates that extreme weather or other conditions will cause delays or force it to halt pickups and deliveries. For the duration of Hurricane Irma, for example, FedEx said it would suspend deliveries in Florida. Some Florida customers who had ordered generators to be delivered via FedEx were unhappy, because they worried about being without power during and after the storm. But one FedEx employee loaded several generator orders into his car and took them to customers himself. When a customer posted a grateful compliment to FedEx on Facebook, the message generated thousands of likes, shares, and positive comments. The company also received positive comments for its donations of cash and transportation services to areas devastated by Hurricanes Irma, Harvey, and Maria. According to the American Customer Satisfaction Index (ACSI), FedEx often tops the list of U.S. shipping companies as ranked by customers surveyed. Every day, the company delivers 13 million packages—and during the busy year-end holiday season, it delivers many more. By meeting customers’ expectations for on-time deliveries, FedEx has increased annual revenues beyond $60 billion and positioned itself for continued growth in the future.

A recurrent problem for Gilman has been coordinating the service teams during the day to determine the status of a job and the need for parts not kept in the service vehicle, as well as to identify which team to send on emergency calls. Gilman's service area is spread over an urban/rural area of approximately 50 square miles. The company has developed cost and price sheets so that the service technicians accurately and consistently price the service work they perform.arrow_forward
- A company is considering opening a fast-food service operation (drive through). Prior research shows that customer arrivals would follow a Poisson process, with an arrival rate of 24 cars per hour, and that service times would follow a negative exponential probability distribution. Arriving customers would place orders at an intercom station at the back of the parking lot and then drive to the service area to pay for and receive their orders. The following service alternatives are being considered: Q1. A single-server operation in one service window in which one employee fills the order and takes the money from the customer. The average service time for this alternative is 2 minutes. - What is the average number of cars waiting for service in the line? Ans= 3.2 Cars - What is the average number of cars in the system?

In some circumstances, where AJAX is too busy and does not have capacity to fulfil deliveries or they do not cover certain areas, only then will Prybloxx make use of a different courier company. Prybloxx has recently had a significant influx of customer complaints regarding goods that have not been delivered, delivered long after the agreed delivery time or damaged once they arrive at the customer. Prybloxx is aware of the effect that this could have on demand for their product, customer goodwill and are now investigating insourcing the delivery of their product to customers. Prybloxx has noted that they have two alternatives in insourcing this department – they can either purchase a local courier company that is considered a going concern or they can purchase all of the required assets and set up such a department themselves.

- Richard Lee, President of Elgin Technology Products, recently returned from a Technology Conference in downtown Chicago. As a result of talking with leaders of other companies, he is now considering establishing a tiered service system, an idea he shared with the manager of the Customer Service Department.Mr. Lee’s basic thought is to reward the customers who give Elgin Technology Products $100,000 worth of business with an end-of-year “thank you payment” that reflects a 5 percent discount on all yearly purchases. In addition, those customers would receive a commitment to next-day turnaround time on the resolution of all customer service problems. Moreover, the customers who purchase $500,000 or more annually would receive a 10 percent discount and a commitment to a four-hour resolution of customer service problems.
