A manager is trying to decide whether to buy one machine or two. If only one is purchased and demand proves to be excessive, the second machine can be purchased later. Some sales will be lost, however, because the lead time for producing this type of machine is six months. In addition, the costper machine will be lower if both are purchased at the same time. The probability of low demand is estimated to be 0.20. The after-tax net present value of the benefits from purchasing the two machines together is $90,000 if demand is low and $180,000 if demand is high. If one machine is purchased and demand is low, the net present value is $120,000. If demand is high, the manager has three options. Doing nothing has a net present value of $120,000; subcontracting, $160,000; and buying the second machine, $140,000.a. Draw a decision tree for this problem.b. How many machines should the company buy initially? What is the expected payoff for this alternative?

One million units are expected to be produced over the life cycle. If the product is made, start-up and production costs of the make decision total $3 million, with a probability of 0.4 that the product will be satisfactory and a 0.6 probability that it will not. If the product is not satisfactory, the firm will have to reevaluate the decision. If the decision is reevaluated, the choice will be whether to spend another $3 million to redesign the semiconductor or to purchase. Likelihood of success the second time that the make decision is made is 0.8. If the second make decision also fails, the firm must purchase. Regardless of when the purchase takes place, Dhakar's best judgment of cost is that Ritz will pay $0.40 for each purchased semiconductor plus $2 million in vendor development cost.
