Instruction: This problem set covers Lecture A5. Each team submits one report. Please submit your report as well as Excel spreadsheet to show your work Monthly demand at G&B Electronics for TVs are as follows: Period Demand (units) 1 2000 2 2113 3 2287 4 2445 5 2558 2648 2755 8 2820 9 2915 10 3008 11 3107 12 3208 ON a. Estimate demand for the next period (period #13) using simple exponential smoothing with alpha=0.35. For this model , use level at Period 0 to be 1-2,655 (the average demand over the 12 periods). b. Evaluate the MADat n=12 c Evaluate the MAPE at n12. d. Evaluate the MSE at n=12
