# Example: Basic demand forecasting algorithm structure
import pandas as pd
from sklearn.ensemble import RandomForestRegressor

def forecast_demand(historical_data, production_schedule):
    """
    Predict future demand based on historical patterns
    and production requirements
    """
    # Feature engineering
    features = [
        'historical_consumption',
        'production_volume',
        'seasonal_factor',
        'supplier_lead_time'
    ]
    
    # Train model on historical data
    model = RandomForestRegressor(n_estimators=100)
    model.fit(historical_data[features], historical_data['actual_demand'])
    
    # Generate forecast
    forecast = model.predict(production_schedule[features])
    return forecast

Intelligent Supplier Selection
