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. Is Ben Gibson acting legally? Is he acting ethically? Why or why not?

You have been asked to estimate the cost of 100 prefabricated structures to be sold to a local school district. Each structure provides 1,000 square feet offloor space, with 8-feet ceilings. In 1999, you produced 70 similar structures consistingof the same materials and having the same ceiling height, but each provided only 800square feet of floor space. The material cost for each structure was $25,000 in 1999, andthe cost capacity factor is 0.65. The cost index values for 1999 and 2006 are 200 and 289,respectively. The estimated manufacturing cost for the first 1,000-square-foot structureis $12,000. Assume a learning curve of 88% and use the cost of the 50th structure asyour standard time for estimating manufacturing cost. Estimate the total material costand the total manufacturing cost for the 100 prefabricated structures.

The Chewy Candy Company would like to determine an aggregate production plan for the next six months. The company makes many different types of candy but feels it can plan its total production in pounds provided that the mix of candy sold does not change too drastically. At the present time, the Chewy Company has 70 workers and 9000 pounds of candy in inventory. Each worker can produce 100 pounds of candy a month and is paid $19 an hour (use 160 hours of regular time per month). Overtime, at a pay rate of 150 percent of regular time, can be used up to a maximum of 20 percent in addition to regular time in any month. It costs 80 cents to store a pound of candy for a year, $1,200 to hire a worker, and $1,500 to lay off a worker. The forecast sales for the next six months are 8000, 10,000, 12,000, 8000, 6000, and 5000 pounds of candy. a.Determine the costs of a level production strategy for the next six months, with an ending inventory of 8000 pounds. b.Determine the costs of a chase…

At Taste of Thyme coffee shop a dirty chai latte creates a profit point of $2.85 for a small and $3.80 for a large. In a month, 200 small lattes were sold and 285 large lattes. As a fast growing demand item with fall approaching, the demand is estimated at 400 and 420 per month. The amount of machine time needed to produce the lattes is 5 minutes and 7 minutes each or for a month, 16.67 hours a month for a small and 33.25 hours a month for a large. What is the maximization function for profit? A. Profit = 400x1 + 420x2 B. Profit = 2.85x1 + 3.80x2 C. Profit = 16.67x1 + 33.25x2 D. Profit = 2.50x1 + 3.50x2

Hudson Corporation is considering three options for managing its data processing operation: continuing with its own staff, hiring an outside vendor to do the managing, or using a combination of its staff and an outside vendor. The profit of the corporation depends on future demand. The annual profit of each option (in thousands of dollars) depends on demand as follows: Demand Staffing Options High Median Low Own staff 650 650 600 Outside vendor 900 600 300 Combination 800 650 500 Recommend a decision based on the use of the optimistic, conservative, and minimax regret approaches. If the demand probabilities are 0.2, 0.5, and 0.3, respectively for High, Median, and Low demands, use the expected value approach to determine the optimal decision(show steps).
1. Foxie Owl’s Besty Bagel shop makes fresh bagels. She has to buy raw materials fresh every day for selling on that day. She wants to know exactly how much should she spend on raw materials. Foxie did some analysis over the past month and came back with the following numbers: Daily demand was equally likely to be 200, 225, 250, 275, or 300 bagels. What should be the number of bagels on hand to satisfy a Fill Rate requirement of 96%, rounded to next integer value? Group of answer choices 300 275 286 263 2. Suppose that instead of a discrete demand distribution, Foxie’s shop determines that the daily demand for bagels is normally distributed, with a mean of 250 and a standard deviation of 35. Foxie still wants a Fill Rate of 98%. What is the appropriate level of on-hand inventory for Foxie’s shop? Group of answer choices 263 274 257 270
Use the following information for the next 3 problems: ABC Company plans to construct a 60,000 sq. ft private warehouse and rent public warehouse as needed. Warehouse inventory turns at the rate of 2 times per month. One pound of merchandise occupies 0.2 cubic feet of warehouse space and can be stacked 10 feet high. Given aisles, and normal operating efficiency, only 50 percent of the total warehouse space is actually used for storage. Assume the facility is being built to size so no additional space is allowed for future product growth. A private warehouse can be constructed for $36 per sq. ft. and can be amortized over 20 years. Annual fixed costs amount to $20 per sq. ft. of total space. The cost of operation is $0.03 per pound of throughput. Space may also be rented for a storage charge on inventory of $0.06 per pound per month and a handling charge of $0.05 per pound of throughput. Monthly demands for a typical year are as follows: Month Demand (lb) Jan 2,000,000…
