After plotting demand for four periods, an emergency room manager has concluded that a trend-adjusted exponential smoothing model is appropriate to predict future demand. The initial estimate of trend is based on the net change of 37 for the three periods from 1 to 4, for an average of +12.33 units. Period Actual Period Actual 1 201 6 268 2 238 7 283 3 233 8 293 4 238 9 298 5 258 10 Use α=0.50 and β=0.10, and TAF of 250 for period 5. Obtain forecasts for periods 6 through 10.
