The time-phased net requirements for the base assembly in a table lamp over the next six weeks are Week Requirements 4 2 200 200 335 3 140 440 300 200 The setup cost for the construction of the base assembly is $200, and the hold- ing cost is $0.30 per assembly per week. a. 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
