What is 'aggregate planning' in production management?
Answer: Medium-term planning to match production capacity with anticipated demand
Aggregate planning sets production, workforce, and inventory levels over a 3-18 month horizon to balance supply and demand.
Which maintenance strategy replaces components at fixed time intervals regardless of their condition?
Answer: Preventive Maintenance
Preventive maintenance follows a scheduled calendar or usage-based plan to prevent failures before they occur.
In MRP (Material Requirements Planning), what three inputs are required to generate the material plan?
Answer: Master Production Schedule, Bill of Materials, and Inventory Records
MRP explodes the MPS through the BOM and adjusts for current inventory records to calculate net material requirements.
What is 'takt time' and how is it calculated?
Answer: Available production time divided by customer demand rate
Takt time sets the production rhythm needed to meet demand: available time ÷ required units = time per unit.
A company produces 200 defective units out of 10,000 total. What is the defect rate in parts per million (PPM)?
Answer: 20,000 PPM
PPM = (defects/total) × 1,000,000 = (200/10,000) × 1,000,000 = 20,000 PPM.
Which capacity planning strategy adds capacity in anticipation of future demand growth?
Answer: Lead Strategy
A lead strategy proactively builds excess capacity before demand materializes, accepting higher costs to avoid lost sales.
What is the primary distinction between 'reliability' and 'maintainability' in production equipment?
Answer: Reliability is the probability of failure-free operation; maintainability is the ease and speed of restoring failed equipment
Reliability (MTBF) measures how long equipment runs without failing; maintainability (MTTR) measures how quickly it is restored after failure.
