A queueing model studies arrivals, waiting and what?
A Surface finish
B Product geometry
C Service capacity
D Maintenance interval
Answer: C. Service capacity. Queueing theory analyzes customers or jobs waiting for service.
Arrival rate is the number of arrivals per what?
A Unit length
B Unit mass
C Production batch
D Unit time
Answer: D. Unit time. Arrival rate measures how frequently customers or jobs enter a system.
Service rate is the number served per what?
A Shift only
B Inventory unit

Answer: D. Unit time. Service rate measures completion capacity per unit time.
For a stable single-server queue, arrival rate must be below what?
A Zero service time
B Inventory level
C Service rate
D Machine cost
Answer: C. Service rate. A stable queue requires the average arrival rate to be less than service capacity.
Little’s Law relates average number in system to flow rate and what?
A Average time
B Unit cost
C Machine count
D Defect rate
Answer: A. Average time. Little’s Law is L = λW, relating WIP, throughput and flow time.
A simulation model imitates system behavior over what?
A Only one static drawing
B A single measurement
C Time
D One product dimension
Answer: C. Time. Simulation represents system dynamics and outcomes over a defined time horizon.
The critical path is the longest-duration path through what?
A Project network
B Warehouse aisles
C Quality chart
D Process capability curve
Answer: A. Project network. The critical path determines the minimum project completion duration.
PERT uses uncertain activity times with what estimates?
A One deterministic estimate
B No duration estimates
C Only a cost estimate
D Three time estimates
Answer: D. Three time estimates. PERT commonly uses optimistic, most-likely and pessimistic durations.
Project float is allowable delay without changing what?
A Completion milestone
B Activity cost
C Resource count
D Quality rating
Answer: A. Completion milestone. Total float is schedule delay available before the project completion date is affected.
A Gantt chart displays tasks against what?
A Product dimensions
B Resource quality
C Inventory value
D Calendar time
Answer: D. Calendar time. Gantt charts visualize activities and durations along a time axis.
A precedence diagram represents what between tasks?
A Material density
B Dependency relationships
C Quality costs
D Machine torque
Answer: B. Dependency relationships. Precedence diagrams show which activities must occur before others.
A bottleneck resource constrains system what?
A Product color
B Supplier distance
C Inventory accuracy
D Throughput
Answer: D. Throughput. System capacity is limited by its most constrained resource.
Theory of Constraints focuses improvement on what?
A Every task equally
B Finished goods only
C Customer price
D System constraint
Answer: D. System constraint. TOC elevates the limiting constraint to improve overall performance.
A plant capacity cushion is extra capacity above what?
A Machine downtime
B Expected demand
C Supplier stock
D Actual quality
Answer: B. Expected demand. A capacity cushion provides flexibility for demand variation and disruptions.
A facility material-flow analysis follows what through plant?
A Movement paths
B Only employee training
C Supplier pricing
D Equipment age
Answer: A. Movement paths. Flow analysis maps movement to reveal distance, congestion and handling waste.
Cross-docking transfers inbound goods directly toward what?
A Outbound shipment
B Long-term storage
C Machine repair
D Quality lab only
Answer: A. Outbound shipment. Cross-docking minimizes storage by moving goods from receiving to shipping.
Warehouse slotting places high-turnover items where?
A Farthest from dispatch
B Only upper shelves
C Easy to access
D Outside the facility
Answer: C. Easy to access. Fast-moving items are placed in convenient locations to reduce picking time.
A process map helps identify steps, delays and what?
