Textbook Question
Chapter 4, Problem 23P
Referring to Problem 7, the operations manager at Macon Controls believes that pessimistic demand has a probability of 20 percent, expected demand has a probability of 50 percent, and optimistic demand has a probability of 30 percent. Currently, new machines must be purchased at a cost of $500,000 a piece, the price charged for each control unit is $110, and the variable cost of production is $50 per unit. (Hint: since the price and variable cost for each control unit are the same, the profit maximizing product mix will be the same as the mix that maximizes the total number of units produced.)
- Draw a decision tree for this problem.
- How many machines should the company purchase, and what is the expected payoff?

Southeastern Airlines's daily flight from Atlanta to Charlotte uses a Boeing 737, with all-coach seating for 120 people. In the past, the airline has priced every seat at $142 for the one-way flight. An average of 79 passengers are on each flight. The variable cost of a filled seat is $26. Aysajan Eziz, the new operations manager,
has decided to try a yield revenue approach, with seats priced at $82 for early bookings and at $187 for bookings within 1 week of the flight. He estimates that the airline will sell 67 seats at the lower price and 34 at the higher price. Variable cost will not change.

The bus of company A has planned their capacity in terms of ‘bus-days’. Forecasts show expected annual demands for the next year to average 400,000 full-day passengers and 840,000 half-day passengers. The company has 61 buses, each with an effective capacity of 40 passengers a day for 300 days a year. Breakdowns and other unexpected problems reduce efficiency to 90%. They employ 86 drivers who work an average of 220 days a year, but illness and other absences reduce their efficiency to 85%. If there is a shortage of buses the company can buy extra ones for $110,000 or hire them for $100 a day. If there is a shortage of drivers they can recruit extra ones at a cost of $20,000 a year, or hire them from an agency for $110 a day.
How can the company approach its tactical planning? Please recommend company A the best plan and explain in detail the reasons for the selection

- A company manufactures a product using two machine cells. Each cell has a design capacity of 250 units per day and an effective capacity of 230 units per day. At present, actual output averages 200 units per cell, but the manager estimates that productivity improvements soon will increase output to 225 units per day. Annual demand is currently 50,000 units. It is forecasted that within two years, annual demand will triple. How many cells should the company plan to produce to satisfy predicted demand under these conditions? Assume 240 workdays per year.arrow_forwardA real estate agent is considering changing her cell phone plan. There are three plans to choosefrom, all of which involve a monthly service charge of $20. Plan A has a cost of $.45 a minute fordaytime calls and $.20 a minute for evening calls. Plan B has a charge of $.55 a minute for daytime calls and $.15 a minute for evening calls. Plan C has a flat rate of $80 with 200 minutes ofcalls allowed per month and a charge of $.40 per minute beyond that, day or evening.a. Determine the total charge under each plan for this case: 120 minutes of day calls and 40 minutes of evening calls in a month.arrow_forwardA biotech firm is considering abandoning its old plant, built 23 years ago, andconstructing a new facility that has 50% more square footage.

The capacity of the new laboratoryis to be 400,000 units per year. During the past 23 years, costs of laboratoryconstruction have risen by an average of 5% per year. If the cost-capacity factor, based on square footage, is 0.80, what is the estimated cost of the newlaboratory?arrow_forward
- Samantha’s Group of Companies is deciding if it should design an advertising system for use on its website. The first option is to skip out on designing, with no net costs or gains. The second option is System A, which would result in additional sales of either $25,000 under good conditions or -$15,000 under bad conditions. The final choice is System B, which would increase sales -$5,000 under both good and bad conditions. Note that it costs $25,000 to develop a system. Assume that good conditions are TWICE as likely as the bad conditions. (Hint: twice as likely means a ratio of 2:1). Outline the ultimate objective for the use of decision trees in product design. How is this objective accomplished? Draw the appropriate decision tree for the above problem.arrow_forwardA manager is trying to decide whether to buy one machine ortwo. If only one machine is purchased and demand provesto be excessive, the second machine can be purchased later.Some sales would be lost, however, because the lead timefor delivery of this type of machine is 6 months. In addition,the cost per machine will be lower if both machines are pur-chased at the same time. The probability of low demand isestimated to be 0.30 and that of high demand to be 0.70. Theafter-tax NPV of the benefits from purchasing two machinestogether is $90,000 if demand is low and $170,000 if demandis high.If one machine is purchased and demand is low, the NPV is$120,000. If demand is high, the manager has three options:(1) doing nothing, which has an NPV of $120,000; (2) subcon-tracting, with an NPV of $140,000; and (3) buying the secondmachine, with an NPV of $130,000.a. Draw a decision tree for this problem.b. What is the best decision and what is its expected payoff?arrow_forwardA real estate agent is considering changing her land line phone plan. There are three plans to choose from, all of which involve a monthly service charge of $20. Plan A has a cost of $.45 a minute for daytime calls and $.20 a minute for evening calls. Plan B has a charge of $.55 a minute for daytime calls and $.15 a minute for evening calls. Plan C has a flat rate of $80 with 200 minutes of calls allowed per month and a charge of $.40 per minute beyond that, day or evening. a. Determine the total charge under each plan for this case: 120 minutes of day calls and 40 minutes of evening calls in a month. b. If the agent will only use the service for daytime calls, over what range of call minutes will each plan be optimal? (Round your answer to the nearest whole number.) c. Suppose that the agent expects both daytime and evening calls. At what point (i.e., percentage of total call minutes used for daytime calls) would she be indifferent between plans A and B?
