Question
SOLVE MANUALLY Inspired by Dell Corporation, Dessa and Lourdes founded a start-up company that assembles customized personal computers from generic parts. To save from material costs, they purchase the generic computer parts in bulk to avail the quantity discount. Thus, an accurate demand forecast for their computers is needed as a basis for the purchasing of the said different computer parts. The two (2) founders were able to compile the demand data from February 2020 to January 2021. Use the demand for Period 1 as both demand and forecast for Period 1. 1. Use exponential smoothing with smoothing parameter a = 0.3 to compute the demand forecast for February 2021 (Period 13). 2. Use exponential smoothing with smoothing parameter a = 0.5 to compute the demand forecast for February 2021 (Period 13). 3. Dessa believes that there is an upward trend in the demand. Use trend-adjusted exponential smoothing with smoothing parameter a = 0.5 and trend parameter B = 0.3 to compute the demand forecast for February 2021 (Period 13). 4. Compute the mean squared error for each of the methods used
