This reorder point is exact arithmetic for one deterministic snapshot, not a stochastic service guarantee.

highlighted = computed this step

Deterministic Snapshot

The rule uses fixed demand, fixed lead time, and fixed safety stock.

Honesty Note

This is deterministic reorder-point arithmetic only. It does not model demand uncertainty, service levels, lead-time uncertainty, supplier reliability, lost sales, or forecast accuracy.
