Which production scheduling technique assigns jobs to machines to minimize total completion time?
Answer: Johnson's Algorithm
Johnson's Algorithm sequences jobs across two machines to minimize makespan (total completion time).
In lean manufacturing, what does 'Poka-Yoke' primarily achieve?
Answer: Prevents defects through error-proofing mechanisms
Poka-Yoke uses physical or digital mechanisms to make errors impossible or immediately detectable.
What is the primary goal of Overall Equipment Effectiveness (OEE)?
Answer: Quantify how effectively manufacturing equipment is utilized
OEE measures availability, performance, and quality to reveal the true productive capacity of equipment.
A manufacturer has a bottleneck workstation processing 80 units/hour while all other stations process 120 units/hour. What is the system throughput?
Answer: 80 units/hour
System throughput is limited by the bottleneck; no station can produce faster than the slowest constraint.
Which inventory costing method assumes the most recently purchased items are sold first?
Answer: LIFO
LIFO (Last-In, First-Out) assumes the newest inventory is consumed first, affecting COGS and tax implications.
What does 'cycle time' represent in a production context?
Answer: Time between successive units coming off the production line
Cycle time is the elapsed time between completing consecutive units at a workstation or production line.
In supply chain management, what is a 'bullwhip effect'?
Answer: Amplification of demand variability as orders move upstream in the supply chain
The bullwhip effect causes small retail demand changes to become exaggerated order swings at the manufacturer and supplier levels.
