AI Supply Chain Optimization

1. 1
   Define Supply Chain Objectives & Data Sources

   Identify specific supply chain problems (e.g., frequent stockouts, excess inventory, long lead times). Pinpoint relevant data sources like historical sales, inventory levels, supplier lead times, and transportation data.
2. 2
   Select AI Tools & Platforms

   Choose your AI development environment. Options include cloud-based AI services (e.g., AWS Sagemaker, Azure ML, Google AI Platform) or open-source libraries (e.g., Python with Prophet, Scikit-learn, TensorFlow) for on-premise or custom solutions.
3. 3
   Collect & Preprocess Data

   Gather historical data for demand forecasting (e.g., daily/weekly sales for at least 1-2 years). Clean the data, handle missing values, and structure it into a time-series format (e.g., 'ds' for date, 'y' for demand) suitable for modeling.
4. 4
   Develop a Demand Forecasting Model

   Train a demand forecasting model using your preprocessed historical data. For a quick start, use a library like Facebook Prophet, which is excellent for time series data with trends and seasonality. Evaluate its performance using metrics like MAE or RMSE.
5. 5
   Implement Basic Inventory Optimization Logic

   Use your demand forecasts to inform inventory decisions. Develop simple rules or calculations for reorder points and quantities, considering lead times, safety stock levels, and holding costs.
6. 6
   Set Up Basic Anomaly Detection (Optional but Recommended)

   For disruption detection, collect operational data (e.g., delivery times, production rates). Use simple statistical methods or machine learning algorithms (e.g., Isolation Forest, Z-score) to detect unusual patterns that might signal a disruption.
7. 7
   Integrate & Monitor Initial AI Agents

   Deploy your trained models (e.g., as simple Python scripts or API endpoints) and integrate them into your existing systems (e.g., ERP, SCM). Set up monitoring to track model performance and alert on significant deviations or detected anomalies.

import pandas as pd
from prophet import Prophet

# Sample Data (replace with your actual historical sales data)
data = {
    'ds': pd.to_datetime(['2022-01-01', '2022-01-08', '2022-01-15', '2022-01-22', '2022-01-29',
                          '2022-02-05', '2022-02-12', '2022-02-19', '2022-02-26', '2022-03-05']),
    'y': [100, 110, 95, 120, 105, 115, 100, 130, 125, 140]
}
df = pd.DataFrame(data)

# Initialize and fit the Prophet model
m = Prophet()
m.fit(df)

# Create a future dataframe for 4 weeks of forecasts
future = m.make_future_dataframe(periods=4, freq='W')

# Make predictions
forecast = m.predict(future)

# Display the next 4 weeks of demand forecasts
print("Next 4 weeks demand forecast:")
print(forecast[['ds', 'yhat', 'yhat_lower', 'yhat_upper']].tail(4))
