The Lake Placid Town Council has decided to build a new community center to be used for conventions, concerts, and other public events, but considerable controversy surrounds the appropriate size. Many influential citizens want a large center that would be a showcase for the area, but the mayor feels that if demand does not support such a center, the community will lose a large amount of money. To provide structure for the decision process, the council narrowed the building alternatives to three sizes: small, medium, and large. Everybody agreed that the critical factor in choosing the best size is the number of people who will want to use the new facility. A regional planning consultant provided demand estimates under three scenarios: worst case, base case, and best case. The worst-case scenario corresponds to a situation in which tourism drops significantly; the base-case scenario corresponds to a situation in which Lake Placid continues to attract visitors at current levels; and the best-case scenario corresponds to a significant increase in tourism. The consultant has provided probability assessments of .10, .60, and .30 for the worstcase, base-case, and best-case scenarios, respectively.
The town council suggested using net cash flow over a five-year planning horizon as the criterion for deciding on the best size. A consultant developed the following projections of net cash flow (in thousands of dollars) for a five-year planning horizon. All costs, including the consultant’s fee, are included.
- a. What decision should Lake Placid make using the
expected value approach? - b. Compute the expected value of perfect information. Do you think it would be worth trying to obtain additional information concerning which scenario is likely to occur?
- c. Suppose the probability of the worst-case scenario increases to .2, the probability of the base-case scenario decreases to .5, and the probability of the best-case scenario remains at .3. What effect, if any, would these changes have on the decision recommendation?
- d. The consultant suggested that an expenditure of $150,000 on a promotional campaign over the planning horizon will effectively reduce the probability of the worst-case scenario to zero. If the campaign can be expected to also increase the probability of the best-case scenario to .4, is it a good investment?

- Due to heavy rains that destroyed numerous roadways in Jamaica the National Works Agency (NWA) has decided to repair 300 km of the Sothern Coastal Highway and 200 km of Type A roads from Kingston to Lucea. The repair will cost $2 million per km for the Type A roads and $8 million per km for the Southern Coastal Highway. The NWA has identified two firms China Harbour and Caribbean Construction. Caribbean Construction can repair at most 300 km while China Harbour has no restriction on the amount of roadway it can repair. Each company must be awarded a contract of at least $300 million (before discounts). Each company wants to maximize the quantity of highway and Type A roads awarded by the NWA so are willing to offer a per km discount. China Harbour offers a discount of 1% for each km of Southern Coastal Highway and Type A road. Caribbean Construction offers a flat discount of $30,000 for each km of Type A road and $50,000 for each km of the Southern CoastalHighway.

One plan is for a series of half-page ads in the Sunday Chicago Tribune newspaper, and the other is for advertising time on Chicago TV. The stores are expanding their lines of do-it-yourself tools, and the advertising director is interested in an exposure level of at least 40% within the city’s neighborhoods and 60% in northwest suburban areas. The TV viewing time under consideration has an exposure rating per spot of 5% in city homes and 3% in the northwest suburbs. The Sunday newspaper has corresponding exposure rates of 4% and 3% per ad. The cost of a half-page Tribune advertisement is $925; a television spot costs $2,000. Diversey Paint would like to select the least costly advertising strategy that would meet desired exposure levels. Formulate using LP. Solve the problem.arrow_forward

Due to mechanical difficulties, however, your ship was forced to land at a spot some 200 miles (320 km) from the rendezvous point. During reentry and landing, much of the equipment aboard was damaged, and because survival depends on reaching the mother ship, the most critical items available must be chosen for the 200-mile (320 km) trip. Please see the list of the 15 items left intact and undamaged after landing. Your task is to rank the items in terms of their importance for your crew to reach the rendezvous point. Place the number 1 by the most important, 2 by the next most important, and so on, with 15 being the least important.arrow_forwardThe Megabuck Hospital Corp. is to build a state-subsidized nursing home catering to homeless patients as well as high-income patients.
