Problem 3:

Develop a net material requirements plan for the TOL and HQ file cabinets in the previous problems assuming a current on-hand finished goods inventory of 100 TOL cabinets. The lead times are given below. Painting and final assembly of both HQ and TOL require 2 weeks. Both cabinet frames and lock assembly require 1 week for manufacturing. Both drawer assemblies require 2 weeks for assembly. Both sliding assemblies require 2 weeks for manufacturing. Bearings require 2 weeks to arrive from the supplier.

Problem 4:

If the TOL file cabinet has a gross material requirements plan as shown below, no inventory, and 2 weeks lead time is required for assembly, what are the order release dates and lot sizes when lot sizing is determined using lot-for-lot? Use a holding cost of $2.00 and a setup cost of $20.00, and assume no initial inventory.

Gross Material Requirements Plan
Week	1	2	3	4	5	6	7	8	9	10
TOL			50		100		50			100

Problem 5: If the TOL file cabinet has a gross material requirements plan as shown below, no inventory, and 2 weeks of lead time is required for assembly, what are the order release dates and lot sizes when lot sizing is determined by EOQ (Economic Order Quantity)? Use a holding cost of $2.00 and a setup cost of $20.00, and assume no initial inventory.
