Question 11 (10 points) a) For the following demand data, use exponential smoothing with alpha = 0.2 to calculate a forecast for period 7. Assume the forecast for period #1 was 7.0. b) Calculate the MAD error for periods 1-6 for your forecast Period Demand 1 10
Use Solver to determine the alpha that minimizes the MAD for the exponential smoothing forecast for the data that appear in this table. Use the actual demand of period 1 as the forecast for period 2 and then use the forecasts for periods 2 through 9 to calculate MAD. Period Demand 1 272 2 278 3 269 4 280 5 267 6 258 7 278 8 298 9 286 10 290 0.43 0.36 0.54 0.62
Use Solver to determine the alpha that minimizes the MSE for the exponential smoothing forecast for the data that appear in this table. Use the actual demand of period 1 as the forecast for period 2 and then use the forecasts for periods 2 through 9 to calculate MSE.
