Using the data below, with a smoothing constant of 0.1 for the base and 0.6 for the trend, compute a trend-adjusted exponential smoothing forecast for period 2. (You are now at the end of period 1.) Period At Ft Tt 1 640 510 80 2

For the next 2 questions, suppose the following had been computed for a set of past forecasts. If the “one-number forecast for next period was 1000, what are the lowest and highest demands that we can possibly expect for next period, using a 99.7% confidence level? MSE = 126 MAPE = 21 Tracking Signal = +5 MAD = 8

Generally speaking and unless we have evidence otherwise, fairly high values of the smoothing constant are good to use with exponential smoothing.

Suppose you have the following information from a forecasting software package. There are three seasons (terms) each year, and the demand data shown below are for the last 2 academic years (Fall, Spring, and Summer of each year). You are now sitting at the end of period 9, which is the last term of the third year. (Note: The best-fit line equation shown below was made up by me; it may not actually be the true equation if you were to do an analysis of this data.) Demand = 310 + 10 (time) What would be the forecast for the Spring term of 2024, if you didn’t care about adjusting for any seasonality?

Suppose the following had been computed for a set of past forecasts. If the “one-number forecast” for next period was 1000, what are the lowest and highest demands that we can possibly expect for next period, using a 99.7% confidence level? MSE = 126 MAPE = 21 Tracking Signal = +5 MAD = 8 Which of the following would be true about the forecasting method being used? I. the method tends to over-forecast II. the method misses by 126 units on average III. the method has been missing by an average of 8%
