The approach for identifying a "lean" schedule for high volume systems was discussed in class. Following this "lean" approach to production scheduling, identify the "ideal" production quantity per cycle for each product in this set of products using the sequence A- B-C-D. You may assume all items are standardized items and have negligible setup times.
