1. The ARA Railroad owns a piece of land along with one of its right-of-ways. The land originally cost ARA $100,000. ARA is considering building a new maintenance facility on this land. ARA determined that the proposal to build the new facility is acceptable if the original cost of the land is used in the analysis, but the proposal does not meet the railroad's project acceptance criteria if the land cost is above $500,000. An investor has recently offered ARA $1 million for the land. Should ARA build the maintenance facility at this location? Why or why not? 2. US Airways owns a piece of land near the Pittsburgh International Airport. The land originally cost US Airways $375,000. The airline is considering building a new training center on this land. US Airways determined that the proposal to build the new facility is acceptable if the original cost of the land is used in the analysis, but the proposal does not meet the airline's project acceptance criteria if the land cost is above $850,000. A developer recently offered US Airways $2.5 million for the land. Should US Airways build the training facility at this location? 3. The Blair Company's three assembly plants are located in California, Georgia, and New Jersey. Previously, the company purchased a major subassembly, which becomes part of the final product, from an outside firm. Blair has decided to manufacture the subassemblies within the company and must now consider whether to rent one centrally located facility (e.g., in Missouri, where all the subassemblies would be manufactured) or to rent three separate facilities, each located near one of the assembly plants, where each facility would manufacture only the subassemblies needed for the nearby assembly plant. A single, centrally located facility, with a production capacity of 18,000 units per year, would have fixed costs of $900,000 per year and a variable cost of $250 per unit. Three separate decentralized facilities, with production capacities of 8,000, 6,000, and 4,000 units per year, would have fixed costs of $475,000, $425,000, and $400,000, respectively, and variable costs per unit of only $225 per unit, owing primarily to the reduction in shipping costs. The current production rates at the three assembly plants are 6,000, 4,500, and 3,000 units, respectively. a. Assuming that the current production rates are maintained at the three assembly plants, which alternative should management select? b. If demand for the final product were to increase to production capacity, which alternative would be more attractive? c. What additional information would be useful before making a decision
