ESSAY QUESTION 2

Billy of Billy's Warehouse in Maine contracts with motor carriers for deliveries thus, they assess him with stiff penalties if their trucks have to wait to be unloaded. He thought about investing considerably in technology and equipment to improve productivity. The subsequent facts apply to his situation:

1) Trucks arrive randomly at the average rate of 5 per hour, with a deviation of plus or minus one.

2) A team of two warehouse workers can unload trucks at the rate of 6 per hour, or one every 10 minutes.

3) A team of four warehouse workers can unload trucks at the rate of 8 per hour, or one every 7.5 minutes

4) A team of six warehouse workers can unload trucks at the rate of 10 per hour, or one every 6 minutes

5) A team of eight warehouse works can unload trucks at the rate of 12 per hour, or one every 5 minutes.

6) Because of its contract with the carriers, the warehouse must pay the motor carrier that own idle trucks at the rate of $100 per hour while the trucks stand idle, waiting to be unloaded.

7) The number of teams or servers is always 1, although the number varies in terms of costs and output.

Part A: Using the queue theory, for each of the four work team sizes, evaluate the expected number of trucks waiting in the queue to be unloaded and evaluate the expected time in the queue- that is the expected time a truck has to wait in line to be unloaded. (Lay out all costs in tabular form)

Part B: Using the number of trucks in queue and the expected time a truck has to wait, along with the rate per hour that he must pay for idle time, calculate how muchBilly is losing with idle trucks with each of the work teams. (Lay out all costs in tabular form)

Part C: Using what you have learned in the text concerning warehouse productivity, how can Billy improve his warehousing productivity without significant investment in technology or equipment?

In the Chippy Potato Chip Case we looked at class rate systems. What do you meant by the class rate system and describe how does the class rate system simplify with respect to product, weight, and distance? Give examples.

ESSAY QUESTION 4

Extreme Hats wanted to bid on a huge festive event of which 6,200 large party hats would be needed. The Style A hats were cylinders that were 11 inches high and 12 inches in diameter and were packed into boxes that were 12 by 12 by 12 inches. The packages cost 80 cents each and weighed 1 pound each. The hats cost $5.00 each to manufacture. They weighed 9 pounds each and 10 pounds packaged. They would be shipped to the Port of Baltimore. The land rate to Baltimore was $2000 per 40 foot container, without regard to weight, although the weight of the load could not exceed 36,000 pounds per loaded container because of highway weight restrictions. The interior dimensions of the intermodal container were 8 feet wide by 8.5 feet high by 40 feet long. Ocean rates from Baltimore to the overseas port were $25 per ton (2,000 pounds), except that the ocean conference used a measurement ton that indicated that for bulky loads every 40 cubic feet would equal 1 ton for rate-making purposes. (That is, a shipment weighing, say 130 pounds and occupying 80 cubic feet would cost as though it weighed 4,000 pounds.) Insurance costs were 5 percent of the value of the shipment ready to be loaded aboard ship in Baltimore.  Extreme Hats decided to custom build and came up with an alternative cone-shaped hat design. Style B hats cost $10 per hat to manufacture and could be shipped nested in packages of 8. The package dimensions were 12 by 12 by 48 inches, and when holding 8 hats a package weighed 75 pounds. Each package cost $5, and this included padding between the hats.

Part A: Extreme Hats is debating whether to use private transportation to get the intermodal containers to the port for this order. Based on information from the text, discuss advantages and disadvantages to private transportation.

Part B: How many of style A hats can be loaded in an intermodal container? How many style B hats can be loaded in an intermodal container?

Part C: What are the total costs of delivering Style A hats to the port of importation? What are the total costs of delivery for Style B hats to the port of importation? (Include all costs in tabular form)

ESSAY QUESTION 5

Bob of Bob's Fish and Tackle, has a business that specialized in the sales of one type of special fishing hook. The annual volume of hooks was 4,000 kegs, and they were sold to retail customers in an even flow. His warehousing costs, was $2 per year per keg space and his order-processing costs were $80 per order without regard to the size. Bob had to rent a constant amount of warehouse space for the year and it had to be large enough to accommodate an entire order when it arrived, he did not maintain safety stock because he bought the hooks on a delivered basis.

Part A: Describe the logic of the EOQ model. Then using the scenario above, and the EOQ methods from the text, how many kegs of fishing hooks should Bob order at one time?

Part B: Suppose all conditions in Part A hold, except that Bob's supplier now provides a quantity discount in the form of absorbing all or part of Bob's order processing costs. For orders of 800 or more kegs of hooks, the supplier will absorb all the order processing costs; for orders between 150 and 799 kegs, the supplier will absorb half. For orders between 100 and 149 kegs, the supplier will absorb a quarter of the costs. Evaluate Bob's new EOQ? (Lay out all costs in tabular form)

Part C: Bob decides to expand his business to contain manufacturing fish bait. He needs to evaluate where to place a new manufacturing facility. From what we learned about facility location decisions, explain how does a raw material's status as pure, weight-losing, or weight-gaining influence the facility location decision? Provide examples of both weight-gaining products and weight-losing products.
