Question
Chapter 14, Problem 10P
a)
Summary Introduction
To develop: A gross requirements plan for all the items.
Introduction:
Gross requirements plan:
The gross requirements plan is the plan where the independent and dependent demand for a product or a component before the on-hand inventory and the scheduled receipts are netted with.
b)
Summary Introduction
To develop: A net requirements plan for all the items.
Introduction:
Net requirements plan:
The net requirements plan is the plan which is established on the gross requirements plan formed by deducting the stock on and the scheduled receipts. If the total requirement is below the safety stock levels, a planned order is made based on the given lot sizing technique.

- Product A is assembled from two units of S1 and threeunits of S2. S1 is made of one unit of C1, four units of C2,and one unit of C3. S2 is made of three units of C2 and twounits of C3.a. Draw a product structure diagram for product A.b. How many C3’s are needed to fill an order for 100 A’s?c. Assume no inventory on hand, products take one day to assemble, subassemblies take two days and compo-nents take three days. When should an order be re-leased for C3 if the 100 A’s are needed by day 7?arrow_forwardDevelop a material requirements plan for component H. Lead times for the end item and each component except B are one week. The lead time for B is three weeks. Sixty units of A are needed at the startof week 8. There are currently 15 units of B on hand and 130 of E on hand, and 50 units of H are inproduction and will be completed by the start of week 2. Lot-for-lot ordering will be used for all items.arrow_forwardProduct X is made of 2 units of Y and 3 of Z. Y is made of 1 unit of A and 2 units of B. Z is made of 2 units of A and 4 units of C. Lead Time of X is 1 week: Y - 2 weeks; Z – 3 weeks; A – 2 weeks; B – 1 week; and C – 3 weeks. Scheduled receipt on week 5 are: A = 250 and Z = 135. If 150 units of X are needed in week 10 & 100 units in week 12, develop a planning schedule showing when each item should be ordered and in what quantity. Use lot for lot except for Y & C which requires minimum of 400 units. Determine the timing of planned release of component Z for the order of 150 units.arrow_forward
