Python Portfolio – Supply Chain & Operations

This repository shows how I apply Python to real-world problems in Supply Chain / Operations.

The focus is not only technical, but also business-oriented: KPIs, inventory decisions and report automation to support management.

Use cases covered

• 📊 OTIF KPI (On Time In Full) by customer and period
• 📦 Inventory management: ABC classification, safety stock and reorder point (ROP)
• ⚙️ Report automation: consolidation of daily files into a weekly Excel report

All data used is dummy/demo, created only to showcase methodology and logic.
