Photochemical reactor modeling: a case-study problem. Although radiation is important in heat transfer, an analogous model can be used in the design of photochemical reactors. The modeling of these reactors….
What is the worst that can happen to Ritz as a result of this particular decision?
Ritz Products’s materials manager, Tej Dhakar, must determine whether to make or buy a new semiconductor for the wrist TV that the firm is about to produce. One million units are expected to be produced over the life cycle. If the prod- uct is made, start-up and production costs of the make decision total $1 million, with a probability of .4 that the product will be satisfactory and a .6 probability that it will not. If the product is not satisfactory, the firm will have to reevaluate the deci- sion. If the decision is reevaluated, the choice will be whether to spend another $1 million to redesign the semiconductor or to purchase. Likelihood of success the second time that the make decision is made is .9. 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 $.50 for each purchased semiconductor plus $1 million in vendor development cost. a) Assuming that Ritz must have the semiconductor (stopping or doing without is not a viable option), what is the best decision? b) What criteria did you use to make this decision? c) What is the worst that can happen to Ritz as a result of this particular decision? What is the best that can happen?
