What lot sizing do you obtain from the EOQ formula? b. Determine the lot sizes using the Silver-Meal heuristic, c. Determine the lot sizes using the least unit cost heuristic, d. Determine the lot sizes using part period balancing, e. Compare the holding and setup costs obtained over the six periods using the poli- cies found in parts (a) through (d) with the cost of a lot-for-lot policy
