Production Scheduling & Capacity Planning Flashcards

Which scheduling technique sequences jobs to minimize the maximum lateness across all orders?

Answer: Earliest Due Date (EDD)

EDD minimizes maximum lateness by prioritizing jobs with the nearest due dates.

In capacity requirements planning (CRP), what input directly determines the load on each work center?

Answer: Planned order releases from MRP

CRP converts MRP planned order releases into detailed load hours at specific work centers.

A production schedule shows a work center loaded at 130% of its rated capacity for three consecutive weeks. The BEST corrective action is to:

Answer: Reschedule orders or add overtime/shifts

Overloads must be resolved by rescheduling orders, adding capacity, or splitting lots.

What does the term 'demonstrated capacity' mean in production scheduling?

Answer: The actual output achieved based on historical performance

Demonstrated capacity is calculated from actual historical performance data, not theoretical maximums.

Which of the following is a characteristic of a BACKWARD scheduling approach?

Answer: It starts from the due date and works backward to determine the start date

Backward scheduling determines the latest possible start date by subtracting lead times from the due date.

A manufacturer is using constraint-based scheduling. Which resource should receive the most scheduling attention?

Answer: The bottleneck resource limiting overall throughput

Theory of Constraints directs that the bottleneck governs total system throughput and must be prioritized.

When calculating the Critical Ratio (CR) for job prioritization, what does a CR value less than 1.0 indicate?

Answer: The job is behind schedule and at risk of being late

A CR below 1.0 means remaining time is less than the remaining work required, signaling likely lateness.
