a. A manufacturing firm manufactures electric motors. The sales during the last four months (starting from the first month) has been: 96, 75, 89, and 68 units. The forecast for the first month was 80 units. Using the exponential smoothing method with a = .70, predict the next month's sales. Calculate the mean absolute percent deviation for this data and comment on the performance of the forecasting method. b. Using the rule lot size=multiple of 50, determine the planned order releases for each week in the following MRP record. The lead time is 2 weeks.
