Pick Path
Also known as: Pick Route, Travel Path, Picking Route
Definition
A pick path is the sequence and route that warehouse workers follow when collecting items to fulfill orders. Optimized pick paths minimize travel distance, reduce picking time, and improve overall warehouse productivity.
Pick Path Strategies
Serpentine (S-Pattern)
- Picker travels up one aisle, down the next
- Simple, intuitive pattern
- Works well for dense picking
Shortest Distance
- Algorithmic optimization
- Visits locations in most efficient order
- Requires WMS support
Zone-Based
- Picker stays within assigned zone
- Reduces travel distance
- Orders consolidated later
Directed
- WMS tells picker exactly where to go
- Optimizes based on current picks
- Most sophisticated approach
Pick Path Optimization Factors
| Factor | Impact |
|---|---|
| Slotting | Fast movers in accessible locations |
| Pick density | Items per path segment |
| Order batching | Combine orders for efficiency |
| Aisle width | Affects equipment and speed |
| Pick method | Each, case, or pallet |
| Equipment | Cart, forklift, conveyor |
Calculating Pick Path Efficiency
Travel Time % = Travel Time ÷ Total Pick Time × 100
Industry benchmarks:
- Poor: 60%+ travel time
- Average: 40-50% travel time
- Good: 30-40% travel time
- Excellent: <30% travel time
Improving Pick Paths
Layout Changes
- Place fast movers near pack stations
- Group frequently ordered together items
- Minimize backtracking requirements
Process Changes
- Batch orders strategically
- Use zone picking for large facilities
- Implement wave planning
Technology
- WMS-directed picking
- Voice picking guidance
- Pick-to-light systems
- Autonomous mobile robots
