# Stellantis Supply Chain Predictive Analytics
## Deep Learning Project Proposal
---
## Executive Summary
This proposal outlines a comprehensive machine learning project targeting the Stellantis automotive supply chain. Based on the analysis of the provided dataset, we propose developing a **Delivery Delay Prediction System** that leverages deep learning techniques to forecast potential delays in vehicle delivery timelines. The project will establish a production-ready MLOps pipeline with continuous monitoring and provide actionable insights through an interactive Power BI dashboard for business stakeholders.
**Key Value Proposition:** By accurately predicting delivery delays 7-14 days in advance, this system will enable proactive inventory management, improve customer satisfaction through accurate delivery estimates, and optimize logistics planning, potentially saving millions in expedited shipping costs and reducing customer dissatisfaction.

## 1. Problem Statement and Business Value
### 1.1 Problem Definition
The automotive industry faces significant challenges in accurately predicting vehicle delivery timelines due to complex global supply chains, manufacturing variability, and logistics disruptions. The Stellantis dataset reveals a critical opportunity to build a predictive system that can:
1. **Forecast delivery delays** before they materialize
2. **Quantify the delay duration** in days
3. **Identify root causes** contributing to delays
4. **Recommend mitigation actions** based on historical success patterns
### 1.2 Business Impact
Successful implementation will deliver:
| Business Area | Impact | Potential Value |
|---------------|--------|-----------------|
| Customer Satisfaction | Provide accurate delivery estimates | Reduced cancellations and improved NPS scores |
| Logistics Planning | Optimize transport mode selection | 5-10% reduction in expedited shipping costs |
| Inventory Management | Better forecasting of vehicle arrival | Reduced lot holding costs and improved cashflow |
| Dealer Relations | Improved transparency on vehicle timelines | Strengthened dealer network confidence |

## 2. Data Understanding and Feature Selection
### 2.1 Target Variable
Based on the analysis of your dataset, the most promising prediction target is:
**`delay_days`** - The numerical difference between expected and actual delivery dates (with 0% missing values in the dataset)
This target allows for both:
- **Regression task**: Predicting the exact number of days of delay
- **Classification task**: Predicting delay risk categories (No Delay, Minor: 1-3 days, Moderate: 4-7 days, Severe: >7 days)
### 2.2 Feature Selection
The following groups of features will be utilized for our model:
#### Core Temporal Features
```
DT_EXPECTED_DELIVERY_TO_FINAL_CUSTOMER_DATE
DT_PROOF_OF_DELIVERY_DATE
DT_ARRIVAL_AT_DESTINATION_BY_TRANSPORTER_DATE
DT_VEHICLE_ASSEMBLY_SHOP_ENTRY_DATE
DT_INGESTION_TIMESTAMP
DT_INGESTION_DATE
```
#### Vehicle Status Flags
```
FL_IS_SHIPPED_TO_COMPOUND_FLAG
FL_IS_VEHICLE_PASSED_TO_SALES_FLAG
FL_IS_VEHICLE_ORDER_IN_PLANT_FLAG
FL_IS_VEHICLE_ORDER_IN_COUNTRY_FLAG

FL_IS_VEHICLE_FOR_SHOWROOM_FLAG
FL_IS_NETWORK_STOCK_IN_TRANSIT_FLAG
FL_IS_VEHICLE_ON_MARKET_COMPOUND_FLAG

## 3. Deep Learning Architecture and Methodology
### 3.1 Model Architecture
We propose a hybrid deep learning approach that combines the strengths of multiple architectures:
**Primary Model: Temporal Fusion Transformer (TFT)**
The TFT architecture is ideal for this supply chain prediction problem because it:
- Handles both temporal and static features effectively
- Captures long-range dependencies in delivery timelines
- Provides interpretable attention weights to identify delay causes
- Supports multi-horizon forecasting (predicting at various points in the supply chain)
**Complementary Models**
1. **LSTM-based Sequence Model**: For capturing complex temporal dependencies in vehicle movement
2. **TabNet**: For handling categorical features with high cardinality (e.g., dealer codes, vehicle configurations)
3. **Gradient Boosting Models**: For baseline comparison and potential ensemble integration
### 3.2 Training Methodology
- **Train/Validation/Test Split**: 70%/15%/15% with time-based splitting to prevent data leakage
- **Loss Function**: Custom weighted MAE/MSE for regression with higher penalties for underestimated delays
- **Validation Strategy**: Time-series cross-validation with expanding window
- **Hyperparameter Optimization**: Bayesian optimization with weighted metrics
- **Transfer Learning**: Pre-train on general automotive delivery data, then fine-tune on Stellantis-specific patterns
### 3.3 Feature Engineering
- **Temporal Features**:
- Day of week, month, quarter for all date fields
- Time deltas between key milestones (e.g., production to shipping)
- Trailing averages of delays by region, vehicle type, dealer
- **Categorical Encodings**:
- Entity embeddings for high-cardinality fields (dealer codes, vehicle models)
- Target encoding for location-based features
- **Derived Features**:
- Supply chain complexity score based on component sourcing
- Distance-based features for manufacturing-to-delivery routes
- Queue position indicators at key bottlenecks
