Q2: Forecasting Analysis: Assum that you got the following values of the number of units sold of Sea Ranch Pizza at PRIMO's during the previous ten years: You were asked to conduct a forecasting analysis to get the potential Sea Ranch Pizza's sales volumes during year 2024 using the following instructions: Year (a) Under what circumstances should PRIMO's use qualitative forecasting? (b) Why do time-series forecasting methods work well for short-term forecasting but do not work very well in long-term forecasting? (7 Marks) Pizza's Sales in Units 2014 20,000 2015 19,000 2016 18,800 2017 18,000 2018 17,000 2019 21,000 2020 19,000 2021 22,800 2022 23,000 2023 20,500 2024 ??

(0.5 mark) (e) Use the following weights to get a weighted forecasted value. (0.07, 0.08, 0.15, 0.18, 0.22, 0.30), Interpret your distributions of weight with different years. (0.5 mark) (f) (g) Use exponential smoothing approach (use a = 0.40 in your analysis). Compute MAD and MSE to compare which one seems the most appropriate and accurate approach of the previous four approaches & why? (h) What is the need to have multiple measures of forecast errors -MAD and MSE? (1.5 marks) (1 mark) (1 mark)
