The H.A.L. Computer Store sells a printer for $200.
The H.A.L. Computer Store sells a printer for $200. Demand for this is constant during the year, and annual demand is forecasted to be 600 units. The holding cost is $20 per unit per year, while the cost of ordering is $60 per order. Currently, the company is ordering 12 times per year (50 units each time). There are 250 working days per year and the lead-time is 10 days.
(a) Given the current policy of ordering 50 units at a time, what is the total of the annual ordering cost and the annual holding cost?
(b) If the company used the absolute best inventory policy, what would the total of the ordering and holding cost be?
(c) What is the reorder point?

| Year | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|
| Heart Transplants | 48.0 | 52.0 | 53.0 | 57.0 | 57.0 |
The director of medical services predicted 6 years ago that demand in year 1 would be 44.0 surgeries.
a) Using exponential smoothing with a of 0.60 and the given forecast for year 1, the forecasts for years 2 through 6 are (round your responses to one decimal place):
| Year | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|
| Forecast | 44.0 | 46.4 | 49.8 | 51.7 | 54.9 | 56.2 |
For the forecast made using exponential smoothing with a = 0.60 and the given forecast for year 1, MAD = 4.1 surgeries (round your response to one decimal place).

Even though independent gasoline stations have been having a difficult time, lan Langella has been thinking about starting his own independent gasoline station. Ian's problem is to decide how large his station should be. The annual returns will depend on both the size of his station and a number of marketing factors related to the oil industry and demand for gasoline. After a careful analysis, lan developed the following table:
States of Nature
| Size of First Station | Good Market | Fair Market | Poor Market |
|---|---|---|---|
| Small | $60,000 | $21,000 | -$12,000 |
| Medium | $70,000 | $32,000 | -$18,000 |
| Large | $95,000 | $32,500 | -$42,000 |
| Very Large | $280,000 | $24,000 | -$150,000 |
For example, if lan constructs a small station and the market is good, he will realize a profit of $60,000.
