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?

A regional distributor purchases discontinued appliances from various suppliers andthen sells them on demand to retailers in the region. The distributor operates 5 daysper week, 52 weeks per year. Only when it is open for business can orders bereceived. The following data are estimated for the mixer:Average daily demand (d) = 100 mixersStandard deviation of daily demand (d) = 30 mixersLead time (L) = 3 daysHolding cost (H) = $9.40/unit/yearOrdering cost (S) = $35/order Cycle-service level = 92 percentSuppose that a periodic review (P) system is used at the distributor. Step 1 : Calculate the P (in workdays, rounded to the nearest day) that givesapproximately the same number of orders per year as the EOQ.
