Weekly tires demand is as follows: Week 1 Demand 143 2 163 3 205 4 266 5 193 6 110 7 163 8 00 120 9 247 10 218 11 175 12 130 1. First use 2-period moving average model to forecast weeks 3 through 12 and evaluates the results by using MAD, MFE, and MAPE. 2. Estimate demand for the next four weeks (week 13 >) using a five-week moving average, as well as simple exponential smoothing with a=0.8 and a=0.2. Explain the impact of alpha. 3. Evaluate the results of the exponential smoothing with = 0.8 and = 0.2. 4. Estimate demand for the next four weeks (week 13 >) using a linear regression model. 5. Develop a regression model with seasonal adjustments for weeks 8 through 12. Compare with the results of Question 4.
