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 SilverMeal heuristic.

c) Determine the lot sizes using the Least Unit Cost heuristic.

d) Determine the lot sizes using Part Period Balancing.

e) Determine the lot size using the WagnerWhitin algorithm.

f) Compare the holding and setup costs obtained over the six periods using the policies found in parts (a) through (e) with the cost of a lot-for-lot policy.

show formulas please.
