CPT CPT Production Planning & Scheduling 4

Question 1

A production scheduler notices that a machine has been down for 4 hours unexpectedly. Which metric is most directly impacted?

Accepted Answer

Overall Equipment Effectiveness (OEE)

Answer

OEE measures availability, performance, and quality, so unplanned downtime directly reduces the availability component of OEE.

Question 2

In a pull-based production system, work orders are released based on:

Accepted Answer

Signals from downstream consumption or demand

Answer

Pull systems release production work only when downstream processes signal a need, preventing overproduction.

Question 3

Which scheduling technique assigns jobs to machines by processing the shortest job first?

Accepted Answer

Shortest Processing Time (SPT)

Answer

SPT prioritizes the job with the least processing time, minimizing average flow time and work-in-process.

Question 4

A plant produces 500 units per 8-hour shift. The takt time is 1 minute per unit. If a bottleneck station can only produce 420 units per shift, what is the best immediate action?

Accepted Answer

Add overtime or a second operator at the bottleneck

Answer

Adding capacity at the bottleneck directly addresses the constraint limiting throughput to below customer takt requirements.

Question 5

What does a Gantt chart primarily display in a production scheduling context?

Accepted Answer

The sequence and timing of jobs across resources

Answer

A Gantt chart shows tasks or jobs plotted against a time axis, illustrating when each job runs on each resource.
