Starbucks has a large, global supply chain the most efficiently supply over 17,000 stores. Although the stores might appear to be fairies similar, they are actually very different. Depending on the location of the store, its size, and the profile of the customer SERV, Starbucks management configures the store offerings to take maximum advantage of the space available in customers preferences.
Starbucks actual distribution system is much more complex, but for the purpose of our exercise let's focus on a single item that is currently distributed through five distribution centers in the United States. Our item is a logo brand and coffee maker that is sold at some of the larger retail stores. The coffee maker is been a study cellar over the years due to his reliability in rugged construction. Starbucks does not consider this a seasonal product, but there is some variablity in demand. Demand for the product over the past 13 weeks is shown in the following table. (week -1 is the week before week 1 in the table, -2 is two weeks before week 1, etc.).
management would like you to experiment with some forecasting models to determine what should be used in the new system to be implemented. The new system is programmed to use one of two forecasting models: simple moving average or exponential smoothing. image text in transcribed

Analytics Exercise 3-02 (Algo) Starbucks has a large, global supply chain that must efficiently supply over 17.000 stores. Although the stores might appear to be very similar, they are actually very different. Depending on the location of the store, its size, and the profile of the customers served, Starbucks management configures the store offerings to take maximum advantage of the space available and customer preferences. Starbucks' actual distribution system is much more complex, but for the purpose of our exercise let's focus on a single item that is currently distributed through five distribution centers in the United States. Our item is a logo-branded coffeemaker that is sold at some of the larger retail stores. The coffeemaker has been a steady seller over the years due to its reliability and rugged construction Starbucks does not consider this a seasonal product, but there is some variability in demand. Demand for the product over the past 13 weeks is shown in the following table (week-1 is the week before week 1 in the table. -2 is two weeks before week 1. etc.).

Consider using a simple exponential smoothing model. In your analysis, test two alpha values, 0.2 and 0.4. When using an alpha value of 0.2 assume that the forecast for week 1 is the past three week average (the average demand for periods -3, -2, and -1). For the model using an alpha of 0.4 assume that the forecast for week 1 is the past five-week average. (Round your answers to 2 decimal places.)
