Scatter plot mapping SKU gross margin against total operational volatility.
Burn-down tracking of active lot shelf-life to prevent default via spoilage.
| Component | Specification & Execution Protocol |
|---|---|
| Data Ingestion | Executed natively on a Windows environment. Automated Python scripts utilize Playwright/Selenium to scrape freight forwarder portals and supplier catalogs. |
| Middleware API | A lightweight Node.js/Express layer receives the scraped JSON payloads from the Windows machines and translates them into parameterized SQL queries to prevent injection attacks. |
| Document Storage | All unstructured background materials (e.g., customs declarations, health certificates, sanitary invoices) are strictly processed, stored in an AWS S3 bucket, and linked in the database strictly as PDFs. |
| Central Ledger | PostgreSQL database acting as the ultimate source of truth, enforcing foreign key constraints between the PDF metadata, supplier entities, and active inventory lots. |
To maintain systemic MECE compliance, the procurement of new Western food products must follow a strict, trigger-based workflow.
| Step | Action | Data Output |
|---|---|---|
| 1. Initiation | The initial input for the automated evaluation pipeline must begin exclusively with The Website of the company that is the seller (the Western manufacturer). The system scrapes this origin for SKU catalogs and MOQ specifications. |
Draft Product Schema |
| 2. Document Verification | Procure sanitary and origin certificates from the supplier. Digitally stamp and store these files strictly as PDFs linked to the supplier's unique ID in the database. | Validated PDFs |
| 3. Volatility Assessment | Calculate expected $\sigma_L$ (Lead Variance) based on historical shipping data from the origin port (e.g., Genoa or Barcelona) to Keelung/Kaohsiung. | Risk Metric Generated |
| 4. Portfolio Decision | Compute the Sharpe Ratio Equivalent. If the score exceeds the baseline threshold, generate an automated Purchase Order via the UI interface. | Executed PO |
| PO Ref | Supplier / Origin | Asset (SKU) | Est. Margin | Status | Action |
