Passenger miles flown on Northeast Airlines, a commuter firm serving the Boston hub, are shown for the past 12 weeks: 1 2 4 5 6 7 8 9 10 12 Week Actual Passenger Miles (in thousands) 3 19 11 15 17 21 23 18 16 20 18 22 20 22 a) Assuming an initial forecast for week 1 of 17,000 miles, use exponential smoothing to compute miles for weeks 2 through 12. Use a=0.2 (round your responses to two decimal places). 1 2 3 4 5 6 7 8 9 10 11 12 Week Forecasted Passenger Miles (in thousands) 17.00 17.00 17.80 18.04 19.03 18.83 18.26 18.61 18.49 19.19 b) The MAD for this model = (round your response to two decimal places). c) Compute the cumulative forecast errors, cumulative MAD, and tracking signals (round your responses to two decimal places). Tracking Signal MAD Week 1 Cumulative Forecast Errors 0.00 4.00 5.20 10.16 Week 7 2.25 MAD 0.00 2.00 1.73 Cumulative Forecast Errors 8.04 7.43 10.94 11.75 Tracking Signal 3.57 3.63 4.96 5.68 8 2 3 2.05 2.21 2.00 3.00 4.00 4.08 9 10 4 2.54 2.07 5 9.13 2.24 11 4 10.16 2.54 4.00 10 11.75 2.07 5.68 5 9.13 2.24 4.08 11 6 6.30 2.34 2.70 12 The control limits for the tracking signal are set at + 4MADs.
