# APS3D (Automatic Pallet Shuttle 3D)
|
|
|
|
## Overview
|
|
|
|
APS3D is a fully automated multi-level warehouse system where mobile carts (shuttles) move throughout the warehouse autonomously to handle container movements. Unlike standard Pallet Shuttle (which uses a single cart per channel), APS3D carts can traverse all aisles of a level (loaded or empty, via passage channels) and change levels via lifts.
|
|
|
|
The carts are directed by a **Fleet Manager** — a centralized controller that receives orders from Easy WMS, assigns them to specific carts, manages traffic, and reports order completion. Locations are of type **APS** or **APSFIFO** for maximum space utilization.
|
|
|
|
## Key capabilities
|
|
|
|
- Fully automated 3D container movement: carts traverse horizontal aisles and change levels via lifts
|
|
- Fleet Manager integration: central controller managing all cart orders and traffic
|
|
- LIFO and FIFO channel modes (APS and APSFIFO location types)
|
|
- Multiple operational modes for the Fleet Manager
|
|
- Order sequencing: configurable sequence levels for multi-level execution
|
|
- Channel compaction: push containers together within a channel to maximize capacity
|
|
- Defragmentation: rotation-based and shipping-based defragmentation across channels
|
|
- Aisle balancing: distribute container load evenly across aisles
|
|
- Error management: extraction and putaway errors with automated recovery
|
|
- Order cancellation and container relocation
|
|
- Pending movement accumulation management
|
|
- Depth confirmation: operator confirms depth for origin/destination
|
|
- Passage channel requests: request free channels for aisle changes
|
|
|
|
## Architecture
|
|
|
|
### System components
|
|
|
|
| Component | Description |
|
|
|-----------|-------------|
|
|
| APS3D carts | Mobile shuttles that carry containers horizontally through aisles and vertically via lifts |
|
|
| Fleet Manager | External controller; receives orders from Easy WMS, assigns to carts, manages traffic, reports completion |
|
|
| Lifts | Allow carts to change warehouse levels |
|
|
| APS / APSFIFO locations | High-density storage channels for compact 3D storage |
|
|
| Passage channels | Empty channels used as transit paths for carts changing aisles |
|
|
|
|
### Fleet Manager work modes
|
|
The Fleet Manager can operate in different modes that affect how orders are processed and assigned to carts. Mode changes are initiated from the Easy WMS interface.
|
|
|
|
### Order flow
|
|
1. Easy WMS generates a container movement task (putaway, extraction, replenishment, etc.)
|
|
2. Easy WMS sends order to Fleet Manager
|
|
3. Fleet Manager assigns available cart
|
|
4. Cart executes movement (horizontal + vertical if level change required)
|
|
5. Fleet Manager reports completion to Easy WMS
|
|
6. Easy WMS confirms task completion
|
|
|
|
### APS vs APSFIFO locations
|
|
- **APS**: standard compact channel, LIFO access
|
|
- **APSFIFO**: FIFO channels for first-in-first-out extraction requirements
|
|
|
|
## Configuration
|
|
|
|
### Prerequisites
|
|
1. Configure APS/APSFIFO locations in EasyS/EasyAssistant
|
|
2. Configure Fleet Manager connection (IP, credentials)
|
|
3. Configure lifts and passage channels
|
|
4. Set APS3D parameters:
|
|
|
|
| Parameter | Description |
|
|
|-----------|-------------|
|
|
| (Various) | APS3D has a dedicated parameter section in Easy WMS parameters (areas/aps3d/parameters.md) |
|
|
|
|
### Warehouse layout
|
|
- Each aisle has defined locations (APS or APSFIFO) at each depth
|
|
- Passage channels designated per level for cart transit
|
|
- Lift stations defined for level changes
|
|
|
|
## Operations
|
|
|
|
### Order management
|
|
All container movements (inbound putaway, outbound extraction, replenishment, internal transfer) are managed through the Fleet Manager. Easy WMS generates tasks → Fleet Manager executes via carts.
|
|
|
|
### Defragmentation
|
|
Three modes specific to APS3D:
|
|
- **Channel compaction**: pushes containers within a channel toward the extraction end
|
|
- **Cross-channel defragmentation**: moves containers between channels for optimization
|
|
- **Rotation defragmentation**: reassigns containers by ABC rotation across channels
|
|
- **Shipping defragmentation**: pre-positions containers toward extraction for pending shipments
|
|
|
|
### Aisle balancing
|
|
Distributes container inventory evenly across aisles to prevent hotspots and optimize cart utilization.
|
|
|
|
### Error management
|
|
- **Extraction error**: no container at pickup location → task managed per location type (APS: cancel + lock; other: hold pending manual)
|
|
- **Putaway error**: destination occupied → Easy WMS searches for alternate location; locks original destination
|
|
|
|
### Depth confirmation
|
|
When the system cannot determine exact depth for origin or destination, an operator confirms the channel depth through the web interface before the order proceeds.
