CPIM Detailed Scheduling and Planning (MRP & Capacity) 1

Question 1

What are the three primary inputs to Material Requirements Planning (MRP)?

Accepted Answer

Master production schedule, bill of materials, and inventory records

Answer

MRP requires the MPS to define what and when to produce, the BOM to define component relationships, and inventory records to determine what is on hand or on order.

Question 2

What does 'net requirements' mean in MRP?

Accepted Answer

Total gross requirements minus on-hand inventory and scheduled receipts

Answer

Net requirements are calculated by subtracting on-hand inventory and scheduled receipts from gross requirements to determine what additional supply is needed.

Question 3

In MRP, 'lot-for-lot' ordering means:

Accepted Answer

Ordering exactly the net requirement for each period with no extra

Answer

Lot-for-lot (L4L) is an MRP lot-sizing rule that orders exactly the quantity needed each period, minimizing carrying costs but potentially increasing ordering costs.

Question 4

Capacity Requirements Planning (CRP) operates on which planning inputs?

Accepted Answer

Planned and released work orders from MRP and routing data

Answer

CRP uses MRP-generated planned and released orders along with routing data (operations, run times, setup times) to calculate detailed load on work centers.

Question 5

What is the purpose of 'pegging' in MRP?

Accepted Answer

Linking component requirements back to the parent demand that caused them

Answer

Pegging traces the source of each component requirement up through the BOM to the specific parent orders or MPS entries that generated them.
