Supply Chain Summary
No data yetFormula used
Total lead time = node lead times + route transit times + customs time + warehouse processing time.
Estimated supply chain cost = node costs + route freight costs + duties + insurance + handling fees.
Capacity utilization = monthly demand ÷ available capacity × 100.
Overall risk score uses the selected Low, Medium, High, or Critical risk level for every mapped node.
How to use this calculator
Enter project information first. Add supply chain nodes and their operational details. Then create transportation routes between those nodes. Use templates when you need a faster starting point. Review the summary, visual map, and analysis table. Apply a scenario to estimate disruption effects. Export your completed data as CSV, PDF, or JSON.
Understanding Supply Chain Mapping
What a supply chain map shows
A supply chain map shows how materials, components, finished goods, information, and returns move between organizations. It connects suppliers, factories, warehouses, ports, distribution centers, retailers, and customers. A useful map does more than display locations. It also records lead times, costs, capacity, inventory, quality, compliance, and risk. These details help teams understand where delays or shortages may begin.
Why multi-tier visibility matters
Many companies know their direct suppliers but lack visibility beyond Tier 1. Multi-tier mapping identifies upstream dependencies that can affect production. A critical component may come from one Tier 2 supplier. That dependency can create unexpected exposure during a disruption. Adding supplier tiers, countries, capacities, and risk ratings makes hidden concentration easier to identify.
Using cost and lead-time information
Lead-time analysis helps teams identify slow stages. Route transit time, customs clearance, production time, and warehouse handling all contribute to total delivery time. Cost data provides another planning dimension. Material costs, freight, duties, insurance, handling, and warehousing can be combined into a practical landed-cost estimate. Comparing routes can reveal faster or cheaper alternatives.
Planning for risk and resilience
Supply chain maps become more valuable when risk is visible. Geographic concentration, supplier dependency, transport disruption, quality issues, financial weakness, and compliance problems can be rated consistently. Scenario planning then tests possible responses. Teams can model delays, capacity reductions, cost increases, port closures, and supplier failures. Alternative suppliers and routes can be documented before emergencies occur. The final map supports clearer sourcing, logistics, inventory, and resilience decisions. Regular updates keep the supply chain view useful.
Example supply chain data
| Stage | Example location | Lead time | Risk | Main metric |
|---|---|---|---|---|
| Tier 2 supplier | Shenzhen, China | 8 days | Medium | Component capacity |
| Manufacturer | Ho Chi Minh City, Vietnam | 5 days | Low | Production utilization |
| Port | Singapore | 2 days | Medium | Customs clearance |
| Distribution center | Rotterdam, Netherlands | 3 days | Low | Inventory days |
Frequently Asked Questions
What is a supply chain map?
It is a visual model of suppliers, facilities, routes, product flows, costs, lead times, and risks.
Can I map Tier 2 and Tier 3 suppliers?
Yes. Select the relevant supplier tier for every upstream node.
How is total lead time calculated?
The tool combines node processing time with route transit time and related operational delays.
Can I compare supply chain risks?
Yes. Each node can be rated Low, Medium, High, or Critical.
Does the tool support scenario planning?
Yes. You can model disruptions, delays, capacity changes, alternative suppliers, route changes, and cost increases.
Can I import existing supplier data?
Yes. The CSV importer accepts node records using the exported CSV column format.
What export formats are available?
You can download CSV, PDF, and JSON files, copy a summary, or print the report.
