Nozone, Inc., a manufacturer of Freon recovery units (for automotive air conditioner maintenance), experiences
a strongly seasonal demand pattern, driven by the summer air conditioning season. This year Nozone has put
together a six-month production plan, where the monthly demands D, for recovery units are given in the table
below. Each recovery unit is manufactured from one chassis assembly plus a variety of other parts. The chassis
assemblies are produced in the machining center. Since there is a single chassis assembly per recovery unit, the
demands in the table below also represent demands for chassis assemblies. The unit cost, fixed setup cost and
monthly holding cost for chassis assemblies are also given in this table. The fixed setup cost is the firm's
estimate of the cost to changeover the machining center to produce chassis assemblies, including labor and
materials cost and the cost of disruption of other product lines.

Her operations manager is considering a new plan, which begins in January with 200 units on hand and ends with zero inventory. Stockout cost of lost sales is $125 per unit. Inventory holding cost is $20 per unit per month. Ignore any idle-time costs. The plan is called plan B.
Plan B: Produce at a constant rate of 1,200 units per month, which will meet minimum demands. Then use subcontracting, with additional units at a premium price of $75 per unit. Subcontracting capacity is limited to 900 units per month. Evaluate this plan by computing the costs for January through August.
In order to arrive at the costs, first compute the ending inventory and subcontracting units for each month by filling in the table below (enter your responses as whole numbers).…
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. Is Ben Gibson acting legally? Is he acting ethically? Why or why not?arrow_forwardScenario 3 Ben Gibson, the purchasing manager at Coastal Products, was reviewing purchasing expenditures for packaging materials with Jeff Joyner.
