Calculate the average number of units sold per station. Calculate the seasonal index. Calculate the average seasonal index. Calculate demand per quarter. Discuss any observed seasonal patterns or variations in estimated demand values. Interpret the results obtained and their implications for demand forecasting.
Exercise 2:
The Patio, Inc. company manufactures patio furniture. From experience, you know that demand is seasonal, that is, there is a greater amount of demand for products in specific periods throughout a year of operations. In order to properly plan its production for the next year, the furniture sales (in units) for the previous two years were reviewed:
