Compare the accuracy of the three forecasts using cumulative error and MAD, and indicate which forecast appears to be most accurate.

Given an actual demand this period of 90, a forecast for this period of 58, and an alpha of 0.2, what would the forecast for the next period be using exponential smoothing?

Here are the actual tabulated demands for an item for a nine-month period (January through September). Your supervisor wants to test two moving average forecasting methods to see which one was better over this period. Month Actual Demand Jan 120 Feb 140 March 160 April 180 May 170 June 190 July 150 August 160 September 170   a. Forecast April through September using a three-month moving average and calculate MAD for the forecasts. b. Forecast May through September using a four-month moving average and calculate MAD for the forecasts.

The worksheet Hudson Demand Case Data in MindTap provides the number of visits over one year from January to December (52 weeks). Chart the data and explain the characteristics of the time series. How would you forecast future demand for customer visits? What criteria will you use to determine a “good” forecast? What methods would you use, and why? What is your final recommendation with respect to a forecasting method? Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism.

Use exponential smoothing with trend adjustment to forecast deliveries for period 5. Let α = 0.1, β = 0.2, and let the initial trend value be 4 and the initial forecast be 200 (both are given in the table).    (a) Complete the table below and to predict the demand for Period 5 (See image).                         Show the calculations for the demand for Period 2.    (b) Based on the actual demands of the first 4 periods forecast the demand for period 5 using the linear regression method.       (c) Which method performs better based on the actual demand for period 5? Why do you think so?
