Order-Up-To Level

Problem

Compute the order-up-to level for periodic review: avg_demand * (lead_time + review_period) + z * sigma_demand * sqrt(lead_time + review_period).

Return 0.0 when the protection interval is negative.

Hint

It is the reorder point computed over the combined lead time and review window.
