As an experienced supply chain planner, you are required to make use of the above data and provide valuable input to Sunrise Baking Company.
1. Develop a daily forecast for this week using a simple four-week moving average.
2. Develop a daily forecast using a weighted moving average with weights 0.40, 0.30, 0.20, and 0.10 (most recent to oldest week).
3. Sunrise is also planning its purchases of ingredients for bread production. If breed demand has been forecast for last week at 22,000 loaves and only 21,000 loaves were actually demanded, what would be Sunrise's forecast for this week using exponential smoothing with α = 0.10?
4. Suppose, with the forecast made in 3 above, this week's demand actually turns out to be 22,500. What would the new forecast be for next week?
5. Comment on the suitability of exponential smoothing as a forecasting tool for the environment in which Sunrise Banking Company operates.
