Manufacturing operations glossary

Clear definitions of the terms behind modern manufacturing operations — from finite scheduling and changeovers to operational digital twins and AI agents. Each term links to related concepts and the ConstraintFlow capability it relates to.

Advanced planning and schedulingAPS

Software that plans what to make and schedules how and when to make it, accounting for real constraints.

Bottleneck

The resource that limits how much the whole operation can produce.

Capacity planning

Making sure you have enough machines, labor, and time to meet demand.

Changeover

The work to switch a line or machine from making one product to another.

Constraint

Anything that limits what the operation can do.

Finite scheduling

Scheduling that respects the real, limited capacity of machines, labor, and materials.

Forecast accuracy

How close forecasts are to what actually happens.

Forecast bias

A consistent tendency to forecast too high or too low.

Human-in-the-loop AI

AI that proposes decisions for people to approve, adjust, or automate.

Infinite scheduling

Scheduling that assumes unlimited capacity, ignoring real resource limits.

Inventory turns

How many times you sell through and replace inventory in a year.

Machine capability

What a specific machine can and cannot make.

Manufacturing AI agent

Software that reasons over your operations and recommends or takes actions.

Manufacturing control tower

A live view of operations that also recommends what to do.

Manufacturing operational intelligence

Turning connected operational data into optimized, explainable decisions.

Master production scheduleMPS

The plan of what finished products to make and when.

Material requirements planningMRP

Calculating what materials to buy or make, and when, to meet the plan.

On-time in-fullOTIF

The share of orders delivered complete and on the promised date.

Operational digital twin

A living data model of how your operation runs, used to make decisions.

Overall equipment effectivenessOEE

A single score for how well a machine is really being used.

Production sequencing

Deciding the order in which jobs run on a line or machine.

Safety stock

Extra inventory held to absorb variability in demand or supply.

Setup time

The time to prepare equipment before a run can start.

Throughput

How much the operation actually produces in a period.
