e. Compare the four forecasting techniques from parts a. through d. using MAD, and recommend which technique is most appropriate for forecasting the MS-14001 milling set and for forecasting the RP-14010 set of 10 -dual-sided replacement tips. f. The general economic forecast for 2018 suggests continued weak corporate investment in new capital manufacturing equipment nationally while demand levels for consumer goods will hold steady. From a qualitative standpoint, how does this effect the forecasts for MS-14001 and RP14010 ? g. Using a simple 5\% increase over each month's sales in 2017, what are the total expected sales of milling sets for each month in 2018 ? h. Given that 75% of the customers are expected to remain loyal to the MS-14001 set, what is the anticipated month-by-month 2018 demand? i. Given that 25% of the customers are expected to move to the MS-1501X milling set, what is the anticipated month-by-month 2018 demand? j. Generally, what are three possible issues with these forecasts? e.
