Problem 8 Question Help Bradley's Copiers sells and repairs photocopy machines. The manager needs weekly forecasts of service calls so that he can schedule service personnel. Use the actual demand in the first period for the forecast for the first week so error measurement begins in the second week. The manager uses exponential smoothing with a = 0.8. Forecast the number of calls for week 6, which is next week. Week 1 2 3 Actual Service Calls 26 32 38 23 25 4 5 The forecast for week 6 is 26.89 service calls. (Enter your response rounded to two decimal places.) X That's incorrect. Remember that exponential smoothing forecasting is based on last period's forecast and the fraction of the difference between last period's forecast and actual demand: F = F4-1 + Q (D4-1-F4-1); where a is a smoothing constant between 0 and 1. OK
