Model allocation using costs and priorities. Estimate split orders, margin impact, stock strain, and speed. Plan smarter routing for faster, cheaper fulfillment outcomes today.
Example order assumptions: quantity 120, revenue $4,200, target delivery 3 days, split penalty 10 points, and backorder penalty $8 per unfilled unit.
| Warehouse | Available Stock | Pick and Pack Cost | Shipping Cost | Transit Days | Capacity Utilization | On-Time Rate |
|---|---|---|---|---|---|---|
| East Hub | 150 | $2.20 | $8.80 | 2 | 68% | 97% |
| Central Hub | 90 | $1.90 | $7.60 | 3 | 74% | 95% |
| West Hub | 60 | $2.50 | $10.20 | 1 | 59% | 98% |
Shipment Cost Score = Minimum warehouse shipment cost ÷ Warehouse shipment cost
Speed Score = Minimum transit days ÷ Warehouse transit days
Stock Score = Minimum of (Available stock ÷ Order quantity) and 1
Capacity Score = 1 − (Capacity utilization ÷ 100)
Reliability Score = On-time rate ÷ 100
Composite Warehouse Score = (Cost weight × Cost score) + (Speed weight × Speed score) + (Stock weight × Stock score) + (Capacity weight × Capacity score) + (Reliability weight × Reliability score)
Scenario Score = (Weighted average warehouse score × 100) − Split penalty − Lateness penalty − Unfilled order penalty
Total Fulfillment Cost = Sum of shipment costs for all used warehouses + (Unfilled units × backorder penalty)
Average Transit = Sum of (Allocated units × transit days) ÷ Fulfilled units
The smart split plan sorts warehouses by composite score and allocates remaining units greedily until the order is covered or stock runs out.
1. Enter the order quantity, revenue, target delivery days, split penalty, and backorder penalty.
2. Set your decision weights to reflect whether cost, speed, stock, capacity, or reliability matters most.
3. Add warehouse stock, pick and pack cost, shipping cost, transit days, utilization, and on-time rate.
4. Submit the form to compare single-source and smart split plans.
5. Review the recommended allocation, scenario ranking, and graph before exporting your report as CSV or PDF.
It balances shipment cost, delivery speed, stock coverage, warehouse capacity pressure, and carrier reliability. The goal is a practical fulfillment recommendation, not just the cheapest warehouse.
It evaluates every single-source option that can cover the full order, then compares them against one smart split scenario. Penalties reduce plans that add fragmentation, lateness, or backorders.
Weights change the importance of each scoring factor. Increasing speed weight favors fast hubs. Increasing cost weight favors cheaper shipment setups. Increasing stock or capacity weight helps protect operational stability.
A slower warehouse may still score better when it is cheaper, has stronger stock coverage, or avoids split shipments. The final recommendation reflects the full tradeoff, not speed alone.
It adds a cost when demand cannot be fully fulfilled. This helps you model lost margin, service recovery, or customer dissatisfaction when stock shortages force delayed shipment.
Yes. Raise the split penalty points when multiple shipments are operationally painful or costly. That pushes the recommendation toward consolidated fulfillment whenever stock and service levels allow it.
No. This is a planning and decision calculator. It helps compare fulfillment options quickly, but it does not replace live inventory synchronization, routing engines, or warehouse execution workflows.
Plan confidence is the adjusted scenario score capped between zero and one hundred. Higher values indicate a stronger balance between economics, service, and operational feasibility under your chosen rules.
