## The Problem

> Logistics networks transport shipments with **partially filled vehicles** due to poor load planning. There is **no AI-driven system** for automatic load consolidation that intelligently groups shipments, maximizes vehicle capacity, simulates strategies, and learns continuously.
>
> At the same time, **15M+ gig delivery workers** in India face systemic dispatch bias — traditional systems assign **3x more deliveries** to some drivers (Gini = 0.85) while others earn near nothing.

**FairRelay solves both.**

---

## Our Solution

FairRelay is a **full-stack AI logistics platform** with two core engines:

| Engine | What It Does | Agents |
|--------|-------------|--------|
| **Load Consolidation Engine** | Groups shipments by geography + time windows, bin-packs into trucks using OR-Tools CP-SAT solver, scores confidence, and learns via Q-Learning | 5 agents |
| **Fair Dispatch Engine** | Allocates routes to drivers using fairness-aware AI with Gini coefficient optimization, wellness tracking, EV-aware routing, and LLM explanations | 8+ agents |

Both engines are orchestrated via **LangGraph** multi-agent workflows, exposed as single API endpoints, and come with live visualization dashboards.

### Hackathon Deliverables Mapping

| Expected Deliverable | Our Implementation |
|---------------------|-------------------|
| **Consolidation Engine Prototype** | 5-agent LangGraph pipeline — KMeans geo-clustering + OR-Tools CP-SAT bin-packing |
| **Visualization Dashboard** | Interactive dark-themed dashboard with Leaflet maps, Chart.js analytics, agent pipeline viz, heatmaps |
| **Performance Simulation** | Multi-scenario simulator comparing Tight/Balanced/Aggressive strategies with full KPI comparison |
| **Continuous Optimization** | Tabular Q-Learning agent with file-based experience store, reward function, and policy recommendation |

### Agent Breakdown

| # | Agent | Algorithm | What It Does |
|---|-------|-----------|-------------|
| 1 | **Geo-Clustering** | scikit-learn KMeans + Silhouette scoring | Groups shipments by pickup/drop proximity. Auto-selects optimal K (2–10). Splits oversized clusters via greedy radius fallback. |
| 2 | **Time-Window** | Interval overlap analysis | Filters clusters by delivery time compatibility. Configurable tolerance (default 120 min). Splits time-incompatible shipments into separate groups. |
| 3 | **Capacity Optimization** | Google OR-Tools CP-SAT Integer Programming | Bin-packs shipments into trucks respecting weight + volume. Minimizes trucks used. Falls back to First-Fit-Decreasing heuristic if solver unavailable. 3-second solver timeout. |
| 4 | **Scoring & Confidence** | Weighted composite scoring | Per-group confidence = `capFit×0.4 + geoScore×0.35 + timeScore×0.25`. Global optimization score factors in utilization, trip reduction, and improvement gain. Computes all KPIs vs naive baseline. |
| 5 | **Continuous Learning** | Tabular Q-Learning (RL) | Stores experience in `data/rl_experience.json` (max 500 episodes). Reward = f(utilization, trips, carbon, score). Updates Q-table to recommend optimal (radius, tolerance) parameters. Detects policy convergence/degradation trends. |

### Consolidation KPIs Produced

| KPI | Description |
|-----|-------------|
| Vehicle Utilization (Before/After) | Percentage improvement from naive to consolidated |
| Trips Reduced | Absolute count + percentage of eliminated trips |
| Distance Saved (km) | Haversine-calculated route distance reduction |
| CO2 Saved (kg) | `distanceSaved × 0.21 kg/km` |
| Carbon Credit Value (USD) | `carbonSaved / 1000 × $25/ton` |
| Fuel Saved (INR) | `distanceSaved × Rs.22.5/km` |
| Cost Reduction (%) | Direct cost savings from trip elimination |
| Optimization Score (0–100) | Weighted composite with letter grade (A+/A/B/C/D) |
| Avg AI Confidence (0–100) | Mean per-group confidence across all bins |

### Scenario Simulation

```
POST /api/v1/consolidate/simulate
```

Run multiple consolidation strategies in parallel and get the best recommendation:

| Scenario | Radius | Time Tolerance | Use Case |
|----------|--------|---------------|----------|
| **Tight Clustering** | 15 km | 60 min | Dense urban, strict deadlines |
| **Balanced** | 30 km | 120 min | General purpose |
| **Aggressive Merge** | 60 km | 240 min | Inter-city, flexible windows |

The system runs all scenarios, compares optimization scores, and recommends the best strategy.

| Agent | Purpose | Key Algorithm |
|-------|---------|---------------|
| **Initialize Node** | Validates inputs, sets up allocation state | Schema validation |
| **Clustering Agent** | Groups packages by geography | K-Means |
| **ML Effort Agent** | Scores driver-route effort pairs | XGBoost |
| **Route Planner** | Solves optimal driver-route assignment | Hungarian Algorithm |
| **Fairness Manager** | Evaluates workload inequality | Gini Index (threshold: 0.25) |
| **EV Recovery Node** | Handles electric vehicle battery constraints | Charging station insertion |
| **Driver Liaison** | Processes driver negotiations/appeals | Rule-based + AI |
| **Learning Agent** | Improves future allocations from feedback | Feedback loop |
| **LLM Explain Node** | Generates natural language explanations | Google Gemini |

### Fairness Algorithms

**Workload Score:**
```
workload = a × num_packages + b × total_weight_kg + c × route_difficulty + d × estimated_time
```

**Gini Index** (0 = perfect equality, 1 = maximum inequality):
```
G = (2 × Σ(i × x_i)) / (n × Σx_i) − (n + 1) / n
```

**Individual Fairness Score:**
```
fairness_score = 1 − |workload − avg_workload| / max(avg_workload, 1)
```

Key Result: **Gini reduced from 0.85 → 0.12** (Grade A fairness)

## Deployment

| Component | Platform | URL Pattern |
|-----------|----------|-------------|
| Brain (AI Engine) | Render | `brain-api.onrender.com` |
| Backend-DM | Render | `backend-dm.onrender.com` |
| Dashboard | Vercel | `dashboard.fairrelay.io` |
| Landing Page | Vercel | `fairrelay.io` |

Both backend services include `render.yaml` for one-click Render deployment. Frontend apps include `vercel.json` with API rewrites configured.

## Usage

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = 'MouleeswaranM/FairRelay'
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id)
```

For non-causal architectures, replace `AutoModelForCausalLM` with the appropriate `AutoModel` class.
