In a Manufacturing Resource Planning (MRP II) system, which module extends basic MRP by incorporating capacity constraints?
Answer: Capacity Requirements Planning (CRP)
CRP uses MRP-generated planned and released orders to calculate load on each work center and compares it to available capacity.
A 'phantom' assembly in a BOM is characterized by:
Answer: A transient assembly that passes through inventory without being stocked
Phantom assemblies are typically built and consumed immediately in the same production run, so MRP is configured to pass demand through them rather than stock them.
Which lot-sizing rule orders exactly the quantity needed in each time period, resulting in zero ending inventory when demand is met?
Answer: Lot-for-Lot (L4L)
Lot-for-Lot orders precisely the net requirement for each period, minimizing carrying costs by avoiding excess inventory between periods.
When an MRP system generates an 'expedite' exception message, it means:
Answer: A planned order should be rescheduled to an earlier date to avoid a shortage
An expedite message alerts the planner that a scheduled receipt needs to be moved earlier because the current timing will result in a projected shortage.
The 'available to promise' (ATP) quantity is most directly linked to which MRP input?
Answer: On-hand inventory and scheduled receipts versus actual customer orders
ATP is calculated by comparing uncommitted supply (on-hand plus scheduled receipts) against actual customer orders to determine what can still be promised.
In MRP, a 'firm planned order' (FPO) differs from a regular planned order because:
Answer: It is frozen and not automatically changed by the MRP system
A firm planned order is manually fixed by the planner so that MRP regeneration will not automatically reschedule or cancel it, preserving intentional planning decisions.
Which of the following best describes 'regenerative MRP'?
Answer: A complete recalculation of all MRP records from scratch on a periodic basis
Regenerative MRP reprocesses the entire MRP database from the MPS downward on a scheduled basis (typically weekly), ensuring all records reflect the current plan.
