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.)

  1. Draw a decision tree for this problem.
  2. How many machines should the company purchase, and what is the expected payoff?

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
