CPIM Detailed Scheduling and Planning 2 — Questions and Answers
Question 1: In MRP terminology, what is a 'scheduled receipt'?
- An open order (purchase or production) already placed and expected to arrive (Correct answer)
- A customer payment
- A forecast entry
- A safety stock quantity
Correct answer: An open order (purchase or production) already placed and expected to arrive
Scheduled receipts are open orders already released that are expected to be received within the planning horizon.
Question 2: What is the purpose of 'action messages' generated by MRP?
- To alert planners to exceptions requiring attention, such as expediting or rescheduling orders (Correct answer)
- To send emails to customers
- To authorize financial payments
- To log quality defects
Correct answer: To alert planners to exceptions requiring attention, such as expediting or rescheduling orders
Action messages notify planners of conditions requiring intervention, such as past-due orders, overdue releases, or excess inventory.
Question 3: Which MRP term refers to the total demand for a component before subtracting available inventory?
- Gross requirements (Correct answer)
- Net requirements
- Projected available balance
- Scheduled receipts
Correct answer: Gross requirements
Gross requirements represent the total quantity of a component needed before considering any on-hand inventory or open orders.
Question 4: What is 'manufacturing lead time' composed of?
- Queue time, setup time, run time, move time, and wait time (Correct answer)
- Only run time and setup time
- Only transportation and receiving time
- Only queue time and move time
Correct answer: Queue time, setup time, run time, move time, and wait time
Manufacturing lead time includes queue, setup, run, move, and wait times for a production order to complete.
Question 5: Which concept allows MRP to plan components across multiple product levels simultaneously?
- Explosion (BOM explosion) (Correct answer)
- Implosion
- Netting
- Offsetting
Correct answer: Explosion (BOM explosion)
BOM explosion passes parent demand down through all BOM levels to generate component requirements at every level.
Question 6: What is a 'firm planned order' (FPO) in MRP?
- A planned order that has been frozen so MRP cannot automatically change its quantity or date (Correct answer)
- A purchase order sent to a supplier
- A completed production job
- A customer shipment confirmation
Correct answer: A planned order that has been frozen so MRP cannot automatically change its quantity or date
An FPO is a planned order that a planner has manually frozen to prevent MRP from automatically rescheduling or changing it.
