Chapter 10.S, Problem 1P
Ace Hardware sells spare parts for lawn mowers. The following data were collected for one week in May when replacement lawn-mower blades were in high demand:
| Day | Demand |
| 1 | 10 |
| 2 | 12 |
| 3 | 13 |
| 4 | 15 |
| 5 | 17 |
| 6 | 20 |
| 7 | 21 |
- a. Simulate a
forecast for the week, starting with F1 = 10. T0 = 2, α = .2, and β = .4. Use the trend model given in the chapter supplement. - b. Compute the MAD and tracking signal for the data. Use MADo = 0
- c. Are the MAD and tracking signal within tolerances?
- d. Simulate a forecast using simple smoothing for the week, starting with F1 = 10 and α = .2. Plot the forecast and the demand on a graph. Note how the forecast lags behind demand.
