A weighted average using weights of 0.40 for the most recent, 0.30 for the next most recent, 0.20 for the next and 0.10 for the next. c. Exponential smoothing constant with alpha =0.40, if May's forecast was 59.2. d. A three-month moving average. e. If the actual demand for June is 62 , forecast the demand for July using the threemonth moving average. a. June =64 b. June Forecast =(0.464)+(0.358)+(0.255)+(0.156)= c. June =59.2+(0.4)(6459.2)= d. (55+58+64)/3= e. (62+58+64)/3=
