Logistics Analysis

A growing collection of simple Python scripts to visualize common flows in Supply Chain Management (SCM) using Matplotlib.

🎯 Goal

Provide visual, data-driven examples of real-world SCM challenges and metrics — from warehouse flow to lead time variability — using clean, well-structured Python code.

📦 SCM examples

Each example will live in its own folder with a self-contained Python script and visualization.

📊 Transportation Cost Analysis

• Analyze transportation costs across different routes

• Use scatter plots to compare cost vs distance

• 📁 Folder: transportation-cost-analysis/

• 📄 Script: transport_cost.py

📈 Product Flow Through Warehouse

• A line chart showing incoming and outgoing product quantities over one week.

• 📁 Folder: product-flow-analysis/

• 📄 Script: productflow.py

📦 Inventory Levels Over Time

• Simulate daily stock levels

• Show reorder points & safety stock

• Visualize with line charts

• 📁 Folder: inventory-levels-over-time/

• 📄 Script: inventory_sim.py

🚚 Order Fulfillment Timeline

• Visualize order entry → processing → shipping

• Use horizontal timeline (e.g., Gantt-style or step lines)

• 📁 Folder: order-fulfillment-timeline/

• 📄 Script: order_timeline.py

⏱️ Lead Time Variability

• Compare supplier lead times

• Use bar charts with error bars to show variability and risk

• 📁 Folder: lead-time-variability/

• 📄 Script: leadtime_chart.py

⚖️ Demand vs Capacity

• Match incoming orders vs available capacity

• Spot bottlenecks with comparative bar charts

• 📁 Folder: demand-vs-capacity/

• 📄 Script: capacity_balance.py

🔁 Cycle Time Analysis

• Show time from raw material to final product

• Use stacked bars or time-flow graphs

• 📁 Folder: cycle-time-analysis/

• 📄 Script: cycle_time.py

🛠 Tech Stack

• Python 3.12+
• Matplotlib
• Virtual Environment (.venv)
• VS Code (recommended)
