Question: You are reevaluating the electrical-generator choice that was made last year-when your boss had your job. The promised cost savings have not materialized, because the generator is too small. You have identified two alternatives. Alternative A is replacing the generator with one that is the right size and selling the old one. That will cost $50K. Alternative B is buying a small generator to use in addition to the one purchased last year. This will cost $60K. The two generator solution has slightly higher maintenance costs, but it is more flexible and reliable. What criteria (including irreducible) should you use? Which alternative would you recommend and why?
