Manufacturing and Production Production Planning and Scheduling 1 — Questions and Answers
Question 1: What is 'capacity planning' in production management?
- Planning warehouse storage space
- Determining the production capacity needed to meet demand over time (Correct answer)
- Scheduling employee vacations
- Designing plant floor layouts
Correct answer: Determining the production capacity needed to meet demand over time
Capacity planning ensures a manufacturing facility has sufficient production resources to meet current and future demand.
Question 2: What does 'bottleneck' mean in a production system?
- A narrow storage aisle
- The operation with the lowest throughput that limits the entire system's output (Correct answer)
- A defective part shape
- An overtime scheduling constraint
Correct answer: The operation with the lowest throughput that limits the entire system's output
A bottleneck is the constraining resource whose limited capacity determines the maximum output of the entire production system.
Question 3: Finite capacity scheduling (FCS) differs from infinite capacity scheduling by:
- Scheduling only day shifts
- Considering actual resource limits when assigning work (Correct answer)
- Using only manual scheduling methods
- Ignoring machine maintenance windows
Correct answer: Considering actual resource limits when assigning work
FCS accounts for real constraints like machine hours and labor availability, unlike infinite scheduling which assumes unlimited capacity.
Question 4: What is a Gantt chart used for in production?
- Charting financial performance
- Visualizing the schedule of tasks over time on a timeline (Correct answer)
- Tracking defect rates
- Displaying inventory levels
Correct answer: Visualizing the schedule of tasks over time on a timeline
A Gantt chart shows production tasks, their durations, sequences, and timing on a horizontal timeline.
Question 5: What does 'cycle time' mean in manufacturing?
- Time between preventive maintenance cycles
- The total time to complete one unit from start to finish at one workstation (Correct answer)
- The time to run one full production shift
- The time between customer orders
Correct answer: The total time to complete one unit from start to finish at one workstation
Cycle time is the elapsed time to produce one unit at a given process step, used to balance workloads and calculate output rates.
Question 6: In production scheduling, 'job shop' scheduling refers to:
- Scheduling jobs at retail stores
- Managing highly customized orders that follow unique routing through various work centers (Correct answer)
- Scheduling in a continuous process facility
- Planning mass production runs
Correct answer: Managing highly customized orders that follow unique routing through various work centers
Job shop scheduling handles custom orders where each job may have a different sequence of operations through shared machines.
