What is the definition of 'demonstrated capacity' on a shop floor?
Answer: The average output actually achieved over a recent representative period
Demonstrated capacity is calculated from actual historical performance data, reflecting what the work center has realistically produced.
An MRP system shows a planned order for 200 units in week 4. The lead time is 2 weeks. In which week will the planned order release appear?
Answer: Week 2
The planned order release is offset back by the lead time: week 4 need − 2 weeks lead time = release in week 2.
Which term describes the total time a job spends in the manufacturing system, including both processing and waiting time?
Answer: Manufacturing lead time
Manufacturing lead time encompasses queue time, setup time, run time, wait time, and move time from order release to completion.
When using the Period Order Quantity (POQ) lot-sizing rule, the order quantity covers:
Answer: A fixed number of future periods' net requirements determined by the EOQ logic
POQ calculates a fixed number of periods to cover (P) from the EOQ and then orders enough to satisfy exactly P periods of net requirements each time.
In a multi-level BOM, MRP processing proceeds by:
Answer: Planning finished goods first, then exploding requirements downward level by level
MRP explodes from the parent item downward, using planned order releases at each level as the gross requirements for the next lower level.
A planner notices that MRP is generating excessive planned orders due to a low-level BOM part being used in many parent assemblies. What technique consolidates these requirements?
Answer: Low-level coding
Low-level coding assigns the lowest level at which a part appears in any BOM so MRP consolidates all demands before planning that part, preventing duplicate orders.
Which production control metric measures the percentage of orders completed on or before the promised due date?
Answer: On-time delivery rate
On-time delivery rate tracks the proportion of customer or internal orders fulfilled by the due date, reflecting scheduling and execution effectiveness.
