Solution

Since there were no forecasts before January we take Jan to be the forecast for February.

∴ Feb - 1200

For March;

March forecast = Feb forecast + 0.3 ( Feb sales - Feb forecast)

= 1200 + 0.3 (1280 - 1200) =1224

Note:

  • The value a lies between 1 and 0.
  • The higher a value, the extra forecast is sensitive to the current status.
