Transworld Deliveries is expanding its contract home delivery service into the Northeastern United States. The company anticipates that to accommodate this expansion it will need between 25 and 40 staffed delivery vehicles. Transworld is currently moving 25 of its own vehicles, with drivers, into the Northeast. The daily cost of operating its own fleet is $820 per vehicle, while the daily cost of leasing a vehicle and driver is expected to be $1,200 per vehicle. The expected demand requirements follow:

. The Newcoat Painting Company has for some time been experiencing high demand for its automobile repainting service. Because it has had to turn away business, management is concerned that the limited space available to store cars awaiting painting has cost them in lost revenue. A small vacant lot next to the painting facility has recently been made available for rental on a long-term basis at a cost of $10 per day. Management believes that each lost customer costs $20 in profit. Current demand is estimated to be 21 cars per day with exponential interarrival times (including those turned away), and the facility can service at an exponential rate of 24 cars per day. Cars are processed on a FCFS basis. Waiting space is now limited to 9 cars but can be increased to 20 cars with the lease of the vacant lot.Newcoat wants to determine whether the vacant lot should be leased. Management also wants to know the expected daily lost profit due to turning away customers if the lot is leased. Only…
Demand for stereo headphones and MP3 players for joggers has caused Nina Industries to grow almost 50 percent over the past year. The number of joggers continues to expand, so Nina expects demand for headsets to also expand, because, as yet, no safety laws have been passed to prevent joggers from wearing them. Demand for the players for last year was as follows:

- Scenario 3 Ben Gibson, the purchasing manager at Coastal Products, was reviewing purchasing expenditures for packaging materials with Jeff Joyner. Ben was particularly disturbed about the amount spent on corrugated boxes purchased from Southeastern Corrugated. Ben said, I dont like the salesman from that company. He comes around here acting like he owns the place. He loves to tell us about his fancy car, house, and vacations. It seems to me he must be making too much money off of us! Jeff responded that he heard Southeastern Corrugated was going to ask for a price increase to cover the rising costs of raw material paper stock. Jeff further stated that Southeastern would probably ask for more than what was justified simply from rising paper stock costs. After the meeting, Ben decided he had heard enough. After all, he prided himself on being a results-oriented manager. There was no way he was going to allow that salesman to keep taking advantage of Coastal Products. Ben called Jeff and told him it was time to rebid the corrugated contract before Southeastern came in with a price increase request. Who did Jeff know that might be interested in the business? Jeff replied he had several companies in mind to include in the bidding process. These companies would surely come in at a lower price, partly because they used lower-grade boxes that would probably work well enough in Coastal Products process. Jeff also explained that these suppliers were not serious contenders for the business. Their purpose was to create competition with the bids. Ben told Jeff to make sure that Southeastern was well aware that these new suppliers were bidding on the contract. He also said to make sure the suppliers knew that price was going to be the determining factor in this quote, because he considered corrugated boxes to be a standard industry item. As the Marketing Manager for Southeastern Corrugated, what would you do upon receiving the request for quotation from Coastal Products?arrow_forwardDemand for stereo headphones and MP3 players for joggers has caused Nina Industries to grow almost 50 percent over the past year.

When their business was small, the drivers of the vans were free to take routes of their choice as they made the delivery rounds to the retail outlets. However, as the business has grown recently due to the outbreak, transportation and delivery costs have become significant. In an effort to improve the efficiency of the delivery operation, MaskMake management would like to determine the shortest delivery routes between retail outlets. For example, the following network shows the roads (distance in km) that may be taken between a retail outlet at node 1 and a retail outlet at node 11. 3 3 6 10 11 6 4 10 1 7 4 2 4 10 Determine the shortest route for a van that is currently at node 1 and must make a delivery to node 11. 2. 3.arrow_forward

Located in a local outdoor shopping center, parking in front of Sonnie’s is limited. However, there are many parking spaces available behind the café within a five-minute walk. The café has an inviting, bright, and open interior with deli cases, blackboards listing specials, and oak tables and chairs. The café’s popularity at lunch is a concern for Sonnie. During the prime lunch time, between 11:30 a.m. and 1:30 p.m. Monday through Friday, the waiting line is often out the door. On average Sonnie would like to serve 40 customers per hour at lunch. Working professionals, who typically spend more than other customers at lunch, are on busy schedules and do not have time to wait in line. Sonnie estimates that currently some customers go to other restaurants because of the line. The menu at Sonnie’s includes nine standard sandwiches such as roast beef, pastrami and rye, and a…arrow_forward
