Question: Aldes is a food and beverage company located in the Republic of Mauritius that is specialized in the export of canned food, such as tuna fish, mainly sold in Africa, the Middle East and Western Europe, in cartons of 48 cans of 185 g each. The monthly exportation value of tuna fish to Jordan during the last eight months is summarized in Table 11. Estimate the two-period-ahead exports of tuna fish by using the exponential smoothing method with a = 0.20, a = 0.25 and a = 0.35. By comparing the obtained results, what is the best value of a? If the company decides to promote the product through a discount policy to increase the sales, how convenient it is to modify the choice of a? Is it possible to use the selected method for six-month-ahead forecasting?
