Hint-Week 4 Chapter 9: see #36 and w37 (Excel) \& Q16 (discussion) In the above data table, the operations manager of Das Manufacturing Company has provided you historical data on their annual requirement of the special component over the past ten years. 122022 (4) What is the forecast requirement for next (i.e., eleventh) year using a two-year and three-year simple moving average? Compute the MSE for each of those two moving averages and compare your results. (4 marks) (5) Using the same data table, find the best single exponential smoothing model by evaluating the MSE, starting with an alpha of 0.10 and changing alpha in increments of 0.10. How does the best single exponential smoothing model compare with the best moving average model you found in (4)? (4 marks) (6) If the DBS operations manager asked for your advice as to whether it is better to use regressionbased forecasting models or time-series forecasting models, what would your advice be and why?
