APICS Master Scheduling & Capacity Planning Flashcards

What is the purpose of 'input/output control' in production activity control?

Answer: Managing the flow of work into and out of a work center to control queue levels

Input/output control compares planned versus actual input and output at work centers to keep queues within planned limits.

Which term describes the total amount of work currently assigned to a work center awaiting processing?

Answer: Queue

The queue is the set of jobs waiting at a work center before processing begins, directly affecting actual lead times.

In production scheduling, 'finite scheduling' differs from 'infinite scheduling' in that finite scheduling:

Answer: Limits planned load to available capacity

Finite scheduling caps the load assigned to each work center at its available capacity, preventing overloading.

The 'theory of constraints' approach to scheduling focuses capacity improvement efforts on:

Answer: The bottleneck or constraint resource

TOC states that overall system throughput is limited by the bottleneck, so maximizing constraint utilization drives total output.

Which master scheduling policy ensures that a time-phased plan accounts for the minimum lot size set by production constraints?

Answer: Fixed order quantity (FOQ)

Fixed order quantity policy orders a predetermined lot size each time, respecting minimum run quantities or tooling constraints.

In master scheduling, 'time-phasing' means:

Answer: Placing demand and supply quantities in specific future time periods

Time-phasing organizes planned demand and supply into discrete time buckets (weeks or days) across the planning horizon.
