Supply Chain Delay Prediction (DataCo Dataset)

This repository contains the trained classification model, feature engineering pipelines, exploratory notebooks, and database integration schemas for predicting supply chain shipment delays.

📊 Model Performance

The predictive model was trained on the DataCo Supply Chain dataset (excluding post-shipment features to avoid data leakage):

• XGBoost Classifier (Best Model):
  • Accuracy: 73.43%
  • ROC-AUC: 83.62%
  • Late Delivery Class Precision: 86% (high precision ensures low false-alarm rates for operations)
• Random Forest Classifier:
  • Accuracy: 72.23%
  • ROC-AUC: 83.68%

Top Feature Importances (XGBoost)

1. days_for_shipping_scheduled (53.4%) - The scheduled shipping window constraint.
2. shipping_mode (23.5%) - Shipping level (First Class, Second Class, Same Day, Standard).
3. order_hour (6.0%) - Time of day the order was placed.
4. type (3.7%) - Transaction/Payment type (Debit, Transfer, etc.)

🛠️ How to Use

1. Requirements

Ensure you have the required libraries installed:

pip install -r requirements.txt

2. Loading the Model and Predicting in Python

import pickle
import pandas as pd

# Load encoders, scaler, and model
with open("Models/label_encoders.pkl", "rb") as f:
    encoders = pickle.load(f)
with open("Models/scaler.pkl", "rb") as f:
    scaler = pickle.load(f)
with open("Models/best_xgb_model.pkl", "rb") as f:
    model = pickle.load(f)

# Example: Make a prediction (ensure feature engineering matches model_training.py)
# predictions = model.predict(X_scaled)
