# Distribution Service (Enterprise Tier)
## Overview
The **Distribution Service** is an enterprise-tier microservice that manages fleet coordination, route optimization, and shipment tracking for multi-location bakery networks. Designed for parent bakeries operating multiple retail outlets, it optimizes daily delivery routes using Vehicle Routing Problem (VRP) algorithms, tracks shipments from central production to retail locations, and ensures efficient inventory distribution across the enterprise network. This service is essential for reducing transportation costs, preventing stockouts at retail locations, and maintaining operational consistency across bakery chains.
**🆕 Enterprise Tier Feature**: Distribution management requires an Enterprise subscription and operates within parent-child tenant hierarchies. This service coordinates inventory transfers between central production facilities (parents) and retail outlets (children).
## Key Features
### Route Optimization
- **VRP-Based Routing** - Google OR-Tools Vehicle Routing Problem solver for optimal multi-stop routes
- **Multi-Vehicle Support** - Coordinate multiple delivery vehicles simultaneously
- **Capacity Constraints** - Respect vehicle weight and volume limitations (default 1000kg per vehicle)
- **Time Window Management** - Honor delivery time windows for each retail location
- **Haversine Distance Calculation** - Accurate distance matrix using geographic coordinates
- **Fallback Sequential Routing** - Simple nearest-neighbor routing when VRP solver unavailable
- **Real-Time Optimization** - 30-second timeout with fallback for quick route generation
### Shipment Tracking
- **End-to-End Visibility** - Track shipments from packing to delivery
- **Status Workflow** - pending → packed → in_transit → delivered → failed
- **Proof of Delivery** - Digital signature, photo upload, receiver name capture
- **Location Tracking** - GPS coordinates and timestamp for current location
- **Parent-Child Linking** - Every shipment tied to specific parent and child tenants
- **Purchase Order Integration** - Link shipments to internal transfer POs from Procurement
- **Weight and Volume Tracking** - Monitor total kg and m³ per shipment
### Delivery Scheduling
- **Recurring Schedules** - Define weekly/biweekly/monthly delivery patterns
- **Auto-Order Generation** - Automatically create internal POs based on delivery schedules
- **Flexible Delivery Days** - Configure delivery days per child (e.g., "Mon,Wed,Fri")
- **Lead Time Configuration** - Set advance notice period for order generation
- **Schedule Activation** - Enable/disable schedules without deletion
- **Multi-Child Coordination** - Single schedule can coordinate deliveries to multiple outlets
### Enterprise Integration
- **Tenant Hierarchy** - Seamless integration with parent-child tenant model
- **Internal Transfer Consumption** - Consumes approved internal POs from Procurement Service
- **Inventory Synchronization** - Triggers inventory transfers on delivery completion
- **Subscription Gating** - Automatic Enterprise tier validation for all distribution features
- **Demo Data Support** - Enterprise demo session integration with sample routes and shipments
### Fleet Management Foundation
- **Vehicle Assignment** - Assign routes to specific vehicles (vehicle_id field)
- **Driver Assignment** - Assign routes to specific drivers (driver_id UUID)
- **Route Sequencing** - JSONB-stored ordered stop sequences with timing metadata
- **Distance and Duration** - Track total_distance_km and estimated_duration_minutes per route
- **Route Status Management** - planned → in_progress → completed → cancelled workflow
## Technical Capabilities
### VRP Optimization Algorithm
⚠️ **Current Implementation**: The VRP optimizer uses Google OR-Tools with a fallback to sequential routing. The OR-Tools implementation is functional but uses placeholder parameters that should be tuned for production use based on real fleet characteristics.
#### Google OR-Tools VRP Configuration
```python
from ortools.constraint_solver import routing_enums_pb2
from ortools.constraint_solver import pywrapcp
# Calculate required vehicles based on demand and capacity
total_demand = sum(delivery['weight_kg'] for delivery in deliveries)
min_vehicles = max(1, int(total_demand / vehicle_capacity_kg) + 1)
num_vehicles = min_vehicles + 1 # Buffer vehicle
# Create VRP model
manager = pywrapcp.RoutingIndexManager(
len(distance_matrix), # number of locations
num_vehicles, # number of vehicles
[0] * num_vehicles, # depot index for starts
[0] * num_vehicles # depot index for ends
)
routing = pywrapcp.RoutingModel(manager)
# Distance callback
def distance_callback(from_index, to_index):
from_node = manager.IndexToNode(from_index)
to_node = manager.IndexToNode(to_index)
return distance_matrix[from_node][to_node]
transit_callback_index = routing.RegisterTransitCallback(distance_callback)
routing.SetArcCostEvaluatorOfAllVehicles(transit_callback_index)
# Add capacity constraint
routing.AddDimensionWithVehicleCapacity(
demand_callback_index,
0, # null capacity slack
[vehicle_capacity_kg] * num_vehicles, # vehicle maximum capacities
True, # start cumul to zero
'Capacity'
)
# Solve with 30-second timeout
search_parameters = pywrapcp.DefaultRoutingSearchParameters()
search_parameters.first_solution_strategy = (
routing_enums_pb2.FirstSolutionStrategy.PATH_CHEAPEST_ARC
)
search_parameters.time_limit.FromSeconds(30.0)
solution = routing.SolveWithParameters(search_parameters)
```
#### Haversine Distance Matrix
```python
import math
def haversine_distance(lat1, lon1, lat2, lon2):
"""Calculate distance between two lat/lon points in meters"""
R = 6371000 # Earth's radius in meters
lat1, lon1, lat2, lon2 = map(math.radians, [lat1, lon1, lat2, lon2])
dlat = lat2 - lat1
dlon = lon2 - lon1
a = math.sin(dlat/2)**2 + math.cos(lat1) * math.cos(lat2) * math.sin(dlon/2)**2
c = 2 * math.asin(math.sqrt(a))
return R * c # Distance in meters
# Build distance matrix for all locations (depot + deliveries)
n = len(locations)
matrix = [[0] * n for _ in range(n)]
for i in range(n):
for j in range(n):
if i != j:
lat1, lon1 = locations[i]
lat2, lon2 = locations[j]
dist_m = haversine_distance(lat1, lon1, lat2, lon2)
matrix[i][j] = int(dist_m)
```
#### Fallback Sequential Routing
If OR-Tools is unavailable or optimization fails, the system uses a simple nearest-neighbor algorithm:
```python
def _fallback_sequential_routing(deliveries, depot_location):
"""
Fallback routing: sort deliveries by distance from depot (nearest first)
"""
# Calculate distances from depot
deliveries_with_distance = []
for delivery in deliveries:
lat, lon = delivery['location']
depot_lat, depot_lon = depot_location
dist = haversine_distance(depot_lat, depot_lon, lat, lon)
deliveries_with_distance.append({
**delivery,
'distance_from_depot': dist
})
# Sort by distance (nearest first)
deliveries_with_distance.sort(key=lambda x: x['distance_from_depot'])
# Build route: depot → delivery1 → delivery2 → ... → depot
route_stops = [{'delivery_id': 'depot_start', 'is_depot': True}]
for i, delivery in enumerate(deliveries_with_distance):
route_stops.append({
'stop_number': i + 2,
'delivery_id': delivery['id'],
'location': delivery['location'],
'weight_kg': delivery.get('weight_kg', 0),
'is_depot': False
})
route_stops.append({'delivery_id': 'depot_end', 'is_depot': True})
return {'routes': [{'route_number': 1, 'stops': route_stops}]}
```
### Distribution Plan Generation Workflow
```
1. Fetch Approved Internal POs
(Procurement Service API call)
Filter by parent_tenant_id + target_date
2. Group by Child Tenant
Aggregate weight, volume, items per child
3. Fetch Tenant Locations
Parent: central_production location (depot)
Children: retail_outlet locations (delivery stops)
4. Build Deliveries Data
[{id, child_tenant_id, location:(lat,lng), weight_kg, po_id}]
5. Call VRP Optimizer
optimize_daily_routes(deliveries, depot_location, capacity)
6. Create DeliveryRoute Records
route_number = R{YYYYMMDD}{sequence}
status = 'planned'
route_sequence = JSONB array of stops
7. Create Shipment Records
shipment_number = S{YYYYMMDD}{sequence}
link to parent, child, PO, route
status = 'pending'
8. Publish Event
RabbitMQ: distribution.plan.created
9. Return Plan Summary
{routes: [...], shipments: [...], optimization_metadata: {...}}
```
### Shipment Lifecycle Management
```
Status Flow:
pending → packed → in_transit → delivered
failed (on delivery issues)
On Status Change to "delivered":
1. Update shipment.actual_delivery_time
2. Store proof of delivery (signature, photo, receiver)
3. Publish event: shipment.delivered
4. Trigger Inventory Transfer:
- Inventory Service consumes shipment.delivered event
- Deducts stock from parent inventory
- Adds stock to child inventory
- Creates stock movements for audit trail
```

async def generate_daily_distribution_plan(
self,
parent_tenant_id: str,
target_date: date,
vehicle_capacity_kg: float = 1000.0

}
# This automatically:
# 1. Creates parent tenant with central_production location
# 2. Creates 3 child tenants with retail_outlet locations
# 3. Calls distribution service demo setup
# 4. Generates sample routes and shipments
# Generate distribution plan for demo tenants
POST http://localhost:8013/api/v1/tenants/{parent_id}/distribution/plans/generate?target_date=2025-11-28
# View created routes
GET http://localhost:8013/api/v1/tenants/{parent_id}/distribution/routes?date_from=2025-11-28
# View created shipments
GET http://localhost:8013/api/v1/tenants/{parent_id}/distribution/shipments?date_from=2025-11-28
```
## Integration Points
### Dependencies (Services This Depends On)
**Tenant Service** - Primary dependency
- **Purpose**: Fetch tenant locations (central_production for parent, retail_outlet for children)
- **Client**: `TenantServiceClient`
- **Methods Used**:
- `get_tenant_locations(tenant_id)` - Fetch geographic coordinates and location types
- `get_tenant_subscription(tenant_id)` - Validate Enterprise tier access
- **Critical For**: Route optimization requires accurate lat/lng coordinates
**Procurement Service** - Primary dependency
- **Purpose**: Fetch approved internal purchase orders for delivery
- **Client**: `ProcurementServiceClient`
- **Methods Used**:
- `get_approved_internal_purchase_orders(parent_id, target_date)` - Get orders ready for delivery
- **Critical For**: Distribution plans are driven by approved internal transfers
**Inventory Service** - Event-driven dependency
- **Purpose**: Inventory transfer on delivery completion
- **Integration**: Consumes `distribution.delivery.completed` events
- **Flow**: Shipment delivered → event published → inventory transferred from parent to child
- **Critical For**: Ensuring stock ownership transfers upon delivery
### Dependents (Services That Depend On This)
**Orchestrator Service**
- **Purpose**: Include distribution planning in daily enterprise orchestration
- **Client**: `DistributionServiceClient`
- **Methods Used**:
- `generate_daily_distribution_plan()` - Trigger route generation
- `get_delivery_routes_for_date()` - Fetch routes for dashboard
- `get_shipments_for_date()` - Fetch shipments for dashboard
- **Use Case**: Enterprise dashboard network overview, distribution metrics
**Demo Session Service**
- **Purpose**: Setup enterprise demo data
- **API Called**: `POST /api/v1/tenants/{id}/distribution/demo-setup` (internal)
- **Use Case**: Initialize sample routes and schedules for demo enterprise networks
## Business Value for VUE Madrid
### Problem Statement
VUE Madrid's bakery clients operating multiple locations (central production + retail outlets) face significant challenges in distribution management:
1. **Manual Route Planning** - 2-3 hours daily spent manually planning delivery routes
2. **Inefficient Routes** - Non-optimized routes waste fuel and time (20-30% excess distance)
3. **Poor Visibility** - No real-time tracking of deliveries leads to stockouts and customer complaints
4. **Ad-Hoc Operations** - Lack of systematic scheduling results in missed deliveries and operational chaos
5. **No Proof of Delivery** - Disputes over deliveries without digital records
6. **Scaling Impossible** - Can't grow beyond 3-4 locations without hiring dedicated logistics staff
### Solution
The Distribution Service provides enterprise-grade fleet coordination and route optimization:
1. **Automated Route Optimization** - VRP algorithm generates optimal multi-stop routes in < 30 seconds
2. **Real-Time Tracking** - GPS-enabled shipment tracking from packing to delivery
3. **Systematic Scheduling** - Recurring delivery patterns (e.g., Mon/Wed/Fri to each outlet)
4. **Digital Proof of Delivery** - Signature, photo, and receiver name for every shipment
5. **Inventory Integration** - Automatic stock transfer on delivery completion
6. **Scalability** - Support up to 50 retail outlets per parent bakery
### Quantifiable Impact
**For Bakery Chains (5+ Locations):**
- **Distance Reduction**: 20-30% less km traveled through optimized routes
- **Fuel Savings**: 200-500/month per vehicle
- **Time Savings**: 10-15 hours/week on route planning and coordination
- **Delivery Success Rate**: 95-98% on-time delivery (vs. 70-80% manual)
- **Scalability**: Support growth to 50 locations without linear logistics cost increase
- **Dispute Resolution**: 100% digital proof of delivery eliminates delivery disputes
**For VUE Madrid:**
- **Market Differentiation**: Only bakery SaaS with enterprise distribution features in Spain
- **Higher Pricing Power**: 299/month (vs. 49/month Professional tier) = 6x revenue per tenant
- **Target Market**: 500+ multi-location bakeries in Spain (vs. 5,000+ single-location)
- **Competitive Moat**: VRP optimization + enterprise hierarchy creates technical barrier to entry
### ROI Calculation
**For Enterprise Customer (10 Locations):**
**Monthly Costs:**
- Fuel savings: 400 (optimized routes)
- Labor savings: 800 (automated planning, 15 hours @ 50/hr)
- Reduced waste: 300 (fewer stockouts from missed deliveries)
- **Total Savings: 1,500/month**
**VUE Madrid Subscription:**
- Enterprise tier: 299/month
- **Net Savings: 1,201/month**
- **ROI: 402% monthly, 4,825% annually**
**Payback Period:** Immediate (first month positive ROI)
**For VUE Madrid:**
- Average customer LTV: 299/month × 36 months = €10,764
- Customer acquisition cost (CAC): 2,000-3,000
- LTV:CAC ratio: 3.6:1 (healthy SaaS economics)
- Gross margin: 90% (software product)
### Target Market Fit
**Ideal Customer Profile:**
- Central production facility + 3-20 retail outlets
- Daily deliveries to outlets (fresh bakery products)
- Current manual route planning (inefficient)
- Growth-oriented (planning to add more locations)
**Spanish Market Opportunity:**
- 500+ multi-location bakery chains in Spain
- 50 enterprise customers @ 299/month = €178,800 ARR
- 200 enterprise customers @ 299/month = €715,200 ARR (achievable in 24 months)
**Competitive Advantage:**
- No Spanish bakery SaaS offers distribution management
- Generic logistics SaaS (e.g., Route4Me) not integrated with bakery ERP
- VUE Madrid offers end-to-end solution: Forecasting Production Procurement **Distribution** Inventory

Demo Distribution History Seeding Script for Distribution Service
Creates 30 days of historical delivery routes and shipments for enterprise demo
This is the CRITICAL missing piece that connects parent (Obrador) to children (retail outlets).
It populates the template with realistic VRP-optimized delivery routes.
Usage:
python /app/scripts/demo/seed_demo_distribution_history.py
Environment Variables Required:
DISTRIBUTION_DATABASE_URL - PostgreSQL connection string
DEMO_MODE - Set to 'production' for production seeding
