09. Explain the need for sales forecasting. How are forecasting methods classified? The past data about the load on a machine centre is as given below: Month, 1 2 3 4 5 6 7 Load 585 611 656 | 748 | 863 | 914 964 Machine -Hours i. If a five month moving average is used to forecast the next month's demand, compute the forecast of the load on the centre in the 8th month. ii. Computea a weighted three month moving average for the gih month, where the weights are 0.5 for the latest month, 0.3 and 0.2 for the other months,

1 A. Forecasting Wallace Garden Supply wants to forecast demand for its Storage Shed. Please find below the actual demands for 8 weeks. Week Demand 131 2 3 4 5 6 7 8 197 162 123 190 145 135 134 1. Find the forecast for week 8 by using moving average methodology. The company use a three- week moving average (n = 3). 2. Find the forecast for week 6 by using weighted moving average methodology. The company use a four-week weighted moving average (n = 4). Weight application is as follows: Weight Application Period 8 5 Last week 2 weeks ago 3 weeks ago weeks ago 4 2 3. Find the forecast for week 7 by using exponential smoothing methodology. Please accept a=0.2 and Forecast for Week 1=130 4. Use the values of actual demands and the values of forecasted demands obtained by using exponential smoothing for all weeks and find MAD (mean absolute deviation). B.
