Which is more common in ERPs?

Infinite-capacity scheduling is the default in nearly every mid-market ERP. Finite-capacity is an optional APS module — and even when installed, it usually runs on a stale snapshot.

Is finite scheduling always better?

For discrete manufacturers with real bottlenecks, yes. For pure flow shops with abundant capacity, the difference is smaller — though even there, finite scheduling produces more accurate promise dates.

Can you switch from infinite to finite without changing ERP?

Yes. A purpose-built scheduling engine layered on top of the ERP can read its work orders and constraints, run finite-capacity logic, and write completions back — no ERP replacement required.

Finite vs Infinite Scheduling — Manufacturing Scheduling Glossary

Definition

Finite vs infinite scheduling describes the two competing assumptions about resource capacity that any production planning system must choose between. Infinite-capacity scheduling allows any work center to absorb any volume of work; finite-capacity scheduling refuses to overload a resource and places operations only where capacity genuinely exists. The choice determines whether the published schedule reflects what the floor can actually run.

Why it matters

Most ERPs default to infinite-capacity scheduling, which silently overloads bottlenecks and produces optimistic promise dates the floor cannot meet. Shops that move to finite-capacity scheduling routinely see on-time delivery rise 15–25 percentage points without buying new machines, because the schedule stops asking the floor to do impossible work.

Common failure mode

A planner releases 80 hours of work to a 40-hour work center. Infinite-capacity logic accepts it. The bottleneck silently doubles in load, operators self-prioritize by gut, and Friday becomes a firefight. The schedule prints clean while the floor runs in chaos.

How Skody approaches it

Skody uses a strict finite-capacity model that includes machines, labor, tooling, pallets, and outside processing. Operations that cannot fit surface as at-risk jobs with the named constraint, so planners can act before the shortfall reaches the floor.

Finite Capacity Scheduling

Scheduling that respects the real, limited capacity of each machine, operator, and tool.

Bottleneck

The resource whose limited capacity governs the throughput of the whole factory.

Available Capacity

The real, bookable hours on each resource after subtracting maintenance, calibration, training, and known constraints.

Production Bottleneck

The single resource whose capacity sets the throughput of the whole factory at a given moment.
