Prevent stockouts and reduce dead-stock carrying costs by hiring senior freelance AI programmer Aldian Fazrihady to build probabilistic demand forecasting and reorder-point engines. Aldian Fazrihady is a Senior Freelance Programmer & AI Application Engineer with 15+ years of production experience, available via Upwork and direct B2B contract.
1. Production Architecture: Probabilistic P50/P90 Demand Forecasting & Lead-Time Aware Safety Stock Calculation
import math
def compute_dynamic_reorder_point(daily_demand_mean: float, daily_demand_std: float, lead_time_days: float, z_score_95: float = 1.645) -> int:
expected_lead_time_demand = daily_demand_mean * lead_time_days
safety_stock = z_score_95 * daily_demand_std * math.sqrt(lead_time_days)
return math.ceil(expected_lead_time_demand + safety_stock)
2. Core Architectural Guarantees
- Multi-Horizon SKU Forecasting: Combining promotional calendars, seasonality, holidays, and price elasticity across thousands of SKUs.
- Supplier Lead-Time Variability Modeling: Dynamically adjusting safety stock when port congestion or vendor delays increase lead-time variance.
- Automated Purchase Order Drafts: Generating container-optimized PO recommendations ready for buyer one-click approval.
