1. The table below shows the demand forecasts for 1991 and 1992. Using the data in the table and the Winters Method: a-) Calculate the initial values of intersection (S0), slope (G0) and seasonal factors (Ci).

b. Assume that the demand for the first quarter of 1993 is 18. Use the parameters = 0,2, = 0,15 and = 0,10 to update the values you have obtained in first part of question.

c. Using the values obtained in option b for the first quarter of 1993, determine the estimated demand for the remaining 3 periods of 1993.
