A small medium-sized, regional beverage producer produces lemonade in three different flavors. As the producer's technical manager, you have set yourself the goal of further optimizing processes and procedures. In a first step, the basis for this is to improve the demand forecast. Based on past values, future demand should be forecasted as accurately as possible. Given the actual requirements of the first three quarters of this year, you want to determine the demand for the first two quarters of next year: Variety/Quarter 1/2018 II/2018 III/2018 Lemon 28.100 34.200 31.300 Elderberry Lychee 10.400 11.000 9.000 8.000 10.200 12.000 Task A: First, consider and discuss whether one of the possible forecasting methods is generally superior. Determine the prognosis values for the different types of lemonade. Use the simple averaging method for the beverage type "lemon", the 1st order exponential smoothing method for the beverage type "elderberry", and the Holt method for the beverage type "lychee". If necessary, make reasonable assumptions for parameters to be used.
