The time-phased net requirements for the base assembly in a table lamp over the next six weeks are: Week 1 2 3 4 5 6 Requirements 335 240 180 320 320 200 The setup cost for the construction of the base assembly is $200, and the holding 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. Determine the lot size using the Wagner-Whitin algorithm. f. Compare the holding and setup costs obtained over the six periods using the policies found in parts (a) through (@) with the cost of a lot-for-lot policy.
