Problem:
Product A is an end item and is made from two units of B and four of C. B is made of three units of D and two of E. Product C is made of two units of F and two of E. Product A has a lead-time of one week. Products B, C and E have lead-times of two weeks. Products D and F have a lead-time of three weeks.
a. Show the bill of material (product structure tree).
b. If 100 units of A are required in week 10, develop the MRP planning schedule, specifying when items are to be ordered and received. There are currently no units of inventory on hand.
If there is a positive net requirement in a week, backward schedule by the lead-time and enter the quantity for the planned order release that will satisfy the net requirement
