2. Metropolitan Manila has four incinerator sites for processing solid waste. There are five garbage collection areas within the metropolis. The city wants to determine the least-cost method of disposing of its trash. Each incinerator is characterized by an operating cost for processing each ton of waste and also a cost for transporting each ton of waste is summarized in the table below: Collection Incinerator Site Area 1 3 4 50 120 110 60 100 55 90 70 60 40 80 65 90 75 85 110 100 95 65 80 Incinerator sites 1 and 2 have a weekly capacity of 6,000 tons each, site 3 has a capacity of 8,000 tons and site 4 has a capacity of 10,000 tons. There are 4,000 tons of waste generated at area A, 8,000 tons at area B and 5,000 tons each at areas C and D, each week. A total of 25.000 tons of waste each week are generated from all five areas. 2.

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?

Civil engineering consulting fi rms that provide ser-vices to outlying communities are vulnerable to a number of factors that affect the fi nancial conditionof the communities, such as bond issues and real estate developments. A small consulting fi rm en-tered into a fi xed-price contract with a large devel-oper, resulting in a stable income of $260,000 per year in years 1 through 3. At the end of that time, a mild recession slowed the development, so the par-ties signed another contract for $190,000 per year for 2 more years. Determine the present worth of thetwo contracts at an interest rate of 10% per year.

E-5 Boston Executive, Inc., produces executive limousines and currently manufactures the mini-bar inset at these costs: (refer the attached image) The company received an offer from Elite Mini-Bars to produce the insets for $2,100 per unit and supply 1,000 mini-bars for the coming year’s estimated production. If the company accepts this offer and shuts down production of this part of the business, production workers and supervisors will be reassigned to other areas. Assume that for the short-term decision-making process demonstrated in this problem, the company’s total labor costs (direct labor and supervisor salaries) will remain the same if the bar inserts are purchased. The specialized equipment cannot be used and has no market value. However, the space occupied by the mini-bar production can be used by a different production group that will lease it for $55,000 per year. Should the company make or buy the mini-bar insert?

Adelie Enterprises is exploring a new service to provideweekly delivery of grocery items to homes in the greaterGreenwood area. The company’s customers place Web-basedorders and Adelie’s team assembles and delivers the orders inspecially designed cardboard boxes. Management, interestedin locating a supplier that can provide boxes cheaply and efficiently, has discovered that each potential supplier’s abil-ity to satisfy the company’s requirements is influenced by thelevel of demand. The following table provides Adelie’s ven-dor selection criteria, criterion weights, and rankings (1–10with 10 being the highest) under the assumption that low,moderate, or high demand is generated for their service. a. Which supplier should be selected if there is low demandfor Adelie’s new service? Which supplier should beselected under moderate demand assumptions? Underhigh demand assumptions?b. Which supplier is selected if Adelie evaluates eachalternative using a Maximin decision criterion…
Roger Co. implemented activity-based costing in the current year. To select the appropriate driver for Cost Pool A, Roger performed regression analyses for two independent variables, Driver 1 and Driver 2, using monthly operating data. The monthly levels of Cost Pool A were the dependent variables in both regressions. Output results from the regression analyses were as follows: Driver 1 R squared Intercept X variable (slope) At the budgeted production level for next month, the levels of Driver 1 and Driver 2 are expected to be 5,880 and 7,000, respectively. Based on this information, what is the budgeted amount for Cost Pool A for next month? O A. $3,280 OB. $2,624 O C. $3,464 O D. $3,785 0.46 $551.00 Driver 2 $0.55 0.80 $970.00 $0.33

TUTORIAL DECISION ANALYSIS 1. e) 0 B) 2. Even though independent gasoline stations have been having a difficult time, Susan Solomon has been thinking about starting her own independent gasoline station. Susan's problem is to decide how large her station should be. The annual returns will depend on both the size of her station and a number of marketing factors related to the oil industry and demand for gasoline. After a careful analysis, Susan developed the following table: Size of First Station Small Medium Large Extra Large Stock Market Bonds CDs Good Market (5) Probability a) b) 50,000 80,000 Decision Alternative. 100,000 300,000 Fair Market (S) 20,000 30,000 30,000 25,000 For example, if Susan constructs a small station and the market is good, she will realize a profit of $50,000. what is the criterion of realism decision?
