What-If and Scope

Honest Product-Mix Scope

Product-mix capacity load is exact arithmetic for one pinned snapshot, not mix optimization.

highlighted = computed this step

Deterministic Snapshot

This snapshot uses fixed capacity, fixed demands, and fixed unit times.

Honesty Note

This is deterministic product-mix capacity-load arithmetic only. It does not model demand uncertainty, setup or changeover time, product sequencing, labor constraints, material constraints, yields, or an optimized product mix.
