Question 17 (3 points) Suppose that an operations manager is trying to determine what forecasting method to use for the following forecasting problem. Based on the following historical data, calculate the following forecasts and specify which forecasting method you would utilize. Month Actual Demand 63 65 1 2 3 4 5 6 AN 68 70 73 75 We can calculate the weighted 3-month forecasts using weights of 0.6, 0.3, and 0.1 for periods 4-6. In particular, the forecast for period 6 is . Question 18 (4 points) Refer to the information in Q17. We can calculate the double exponential smoothing forecasts for periods 2-6 using an initial trend forecast (T1) of 1.8, and initial exponential smoothing forecast (S1) of 60, an a of 0.30 and a B of 0.30. In particular, the forecast for period 3 is In particular, the forecast for period 3 is 64.8480 68.1653 71.2525 74.4708
