What-If and Scope

Honest Efficiency Scope

Line-balancing efficiency is exact arithmetic for fixed station loads, not a full balancing optimizer.

highlighted = computed this step

Deterministic Snapshot

The calculation uses fixed station loads and fixed cycle times.

Honesty Note

This is deterministic station-load arithmetic only. It does not model task precedence, ergonomics, stochastic task times, staffing, learning, quality, or a global line-balancing optimum.
