Tropical Seafoods is a small new restaurant that has opened in town. Sales have been steadily increasing as “word of mouth” has spread through the capital. In its first 12 weeks, sales at Tropical Seafoods (in $ 1000s) have been: WEEK SALES 1 18 2 22 3 26 4 24 5 28 6 32 7 32 8 40 9 38 10 42 11 40 12 46 1. Using a weighted moving average with three periods, determine the sales for period 13. Use 3, 2, and 1 for the weights of the most recent, second most recent, and third most recent periods, respectively 2. Find the MAD, MSE and MAPE 3. Use exponential smoothing with a smoothing constant of 0.50 to forecast the sales (Assume that last period’s forecast for period 1 is equal to actual to begin the procedure (Ft1=Yt1). Which method do you think is best? Is this an improvement over the weighted average- use MAD only
