Forecasting techniques generally assume an existing causal system that will continue to exist in the future. Register to View AnswerDifficulty: Medium Page: 69 2. For new products in a strong growth mode, a low alpha will minimize forecast errors when using exponential smoothing techniques. Register to View AnswerDifficulty: Medium Page: 83 3. Once accepted by managers, forecasts should be held firm regardless of new input since many plans have been made using the original forecast. Register to View AnswerDifficulty: Easy Page: 70 4. Forecasts for groups of items tend to be less accurate than forecasts for individual items because forecasts for individual items dont include as many influencing factors. Register to View AnswerDifficulty: Medium Page: 69 5. Forecasts help managers plan both the system itself and provide valuable for information using the system. Register to View AnswerDifficulty: Easy Page: 68 17 6. Organizations that are capable of responding quickly to changing requirements can use a shorter forecast horizon and therefore benefit from more accurate forecasts. Register to View AnswerDifficulty: Medium Page: 70 Learning Objective: IT 7. MAD is endorsed by the American Statistical Society while MAPE is the choice of the Decision Science Association.. Register to View AnswerDifficulty: Easy Page: 92 8. The purpose of the forecast should be established first so that the level of detail, amount of resources, and accuracy level can be understood. Register to View AnswerDifficulty: Medium Page: 92 9. Forecasts based on time series (historical) data are referred to as associative forecasts. Register to View AnswerDifficulty: Easy Page: 88 18 10. Time series techniques involve identification of explanatory variables that can be used to predict future demand. Register to View AnswerDifficulty: Hard Page: 72 11. A consumer survey is an easy and sure way to obtain accurate input from future customers since most people enjoy participating in surveys. Register to View AnswerDifficulty: Easy Page: 71 12. The Delphi approach involves the use of a series of questionnaires to achieve a consensus forecast. Register to View AnswerDifficulty: Easy Page: 72 13. Exponential smoothing adds a percentage (called alpha factor) of last periods forecast to estimate next periods demand. Register to View AnswerDifficulty: Medium Page: 77 14. The shorter the forecast period, the more accurately the forecasts tend to track what actually happens. Register to View AnswerDifficulty: Easy Page: 69 15. Forecasting techniques that are based on time series data assume that future values of the series will duplicate past values. Register to View AnswerDifficulty: Medium Page: 72 16. Trend adjusted exponential smoothing uses double smoothing to add twice the forecast error to last periods actual. Register to View AnswerDifficulty: Medium Page: 82 17. Forecasts based on an average tend to exhibit less variability than the original data. Register to View AnswerDifficulty: Medium Page: 74 18. The naive approach to forecasting requires a linear trend line. Register to View AnswerDifficulty: Easy Page: 73 19. The naive forecast is limited in its application to series that reflect no trend or seasonality. Register to View AnswerDifficulty: Easy Page: 73 20. The naive forecast can serve as a quick and easy standard of comparison against which to judge the cost and accuracy of other techniques. Register to View AnswerDifficulty: Easy Page: 73 19 21. A moving average forecast tends to be more responsive to changes in the data series when more data points are included in the average. Register to View AnswerDifficulty: Medium Page: 74 22. In order to update a moving average forecast, the values of each data point in the average must be known. Register to View AnswerDifficulty: Hard Page: 74 23. Forecasts of future demand are used by operations people to plan capacity. Register to View AnswerDifficulty: Easy Page: 99 24. An advantage of a weighted moving average is that recent actual results can be given more importance than what occurred a while ago. Register to View AnswerDifficulty: Medium Page: 74 25. Exponential smoothing is a form of weighted averaging. Register to View AnswerDifficulty: Medium Page: 77 26. A smoothing constant of .1 will cause an exponential smoothing forecast to react more quickly to a sudden change than a smoothing constant value of .3. Register to View AnswerDifficulty: Hard Page: 77 27. The T in the model TAF = S+T represents the time dimension (which is usually expressed in weeks or months). Register to View AnswerDifficulty: Medium Page: 82 28. Trend adjusted exponential smoothing requires selection of two smoothing constants. Register to View AnswerDifficulty: Easy Page: 82 29. An advantage of "trend adjusted exponential smoothing" over the "linear trend equation" is its ability to adjust over time to changes in the trend. Register to View AnswerDifficulty: Medium Page: 82 30. A seasonal relative (or seasonal indexes) is expressed as a percentage of average or trend. Register to View AnswerDifficulty: Medium Page: 84 31. In order to compute seasonal relatives, the trend of past data must be computed or known which means that for brand new products this approach cant be used. Register to View AnswerDifficulty: Medium Page: 84 20 32. Removing the seasonal component from a data series (de-seasonalizing) can be accomplished by dividing each data point by its appropriate seasonal relative. Register to View AnswerDifficulty: Hard Page: 84 33. If a pattern appears when a dependent variable is plotted against time, one should use time series analysis instead of regression analysis. Register to View AnswerDifficulty: Hard Page: 92 Learning Objective: AS 34. Curvilinear and multiple regression procedures permit us to extend associative models to relationships that are non-linear or involve more than one predictor variable. Register to View AnswerDifficulty: Medium Page: 92 35. The sample standard deviation of forecast error, is equal to the square root of MSE. Register to View AnswerDifficulty: Easy Page: 92 36. Correlation measures the strength and direction of a relationship between variables. Register to View AnswerDifficulty: Medium Page: 91 37. MAD is equal to the square root of MSE which is why we calculate the easier MSE and then calculate the more difficult Mean Absolute Deviation. Register to View AnswerDifficulty: Medium Page: 92 38. In exponential smoothing, an alpha of 1.0 will generate the same forecast that a nave forecast would yield. Register to View AnswerDifficulty: Medium Page: 77 39. A forecast method is generally deemed to perform adequately when the errors exhibit an identifiable pattern. Register to View AnswerDifficulty: Medium Page: 92 40. A control chart involves setting action limits for cumulative forecast error. Register to View AnswerDifficulty: Medium Page: 92 41. A tracking signal focuses on the ratio of cumulative forecast error to the corresponding value of MAD. Register to View AnswerDifficulty: Medium Page: 92 42. The use of a control chart assumes that errors are normally distributed about a mean of zero. Register to View AnswerDifficulty: Hard Page: 92 21 43. Bias exists when forecasts tend to be greater or less than the actual values of time series. Register to View AnswerDifficulty: Easy Page: 92 44. Bias is measured by the cumulative sum of forecast errors. Register to View AnswerDifficulty: Medium Page: 92 45. Seasonal relatives can be used to de-seasonalize data or incorporate seasonality in a forecast. Register to View AnswerDifficulty: Medium Page: 3-22 46. The best forecast is not necessarily the most accurate. Register to View AnswerDifficulty: Medium Page: 92 Learning Objective: Ref 47. A proactive approach to forecasting views forecasts as probable descriptions of future demand, and requires action be taken to meet that demand. Register to View AnswerDifficulty: Hard Page: 99 48. Simple linear regression applies to linear relationships with no more than three independent variables. Register to View AnswerDifficulty: Medium Page: 88 49. An important goal of forecasting is to minimize the average forecast error. Register to View AnswerDifficulty: Medium Page: 92 50. Forecasting techniques such as moving averages, exponential smoothing, and the naive approach all represent smoothed (averaged) values of time series data. Register to View AnswerDifficulty: Medium Page: 72 51. In exponential smoothing, an alpha of .30 will cause a forecast to react more quickly to a large error than will an alpha of .20. Register to View AnswerDifficulty: Medium Page: 77 Multiple Choice 52. Forecasts based on judgment and opinion dont include A) executive opinion B) salesperson opinion C) second opinions D) customer surveys E) Delphi methods Register to View AnswerDifficulty: Medium Page: 71 22 57.
