📋 Overview
The Shipping Space TabPage calculates the required floor footprint for picking, inspection, packing, temporary staging, and shipping dock areas based on outbound throughput parameters.
💡 What is TabPage?
A TabPage represents an individual tab screen within a master TabControl container. In the distribution center sizing suite, multiple calculation modules are organized into distinct tabs, with "Shipping Space" implemented as one dedicated screen.
- One dedicated tab page inside the master TabControl container
- Consolidates all shipping dock and staging area calculation parameters
- Integrates with other module tabs (Inbound, Storage, etc.)
- Supports standalone calculations and reporting views
🎯 Purpose & Applications
1. Determining Optimal Shipping Footprint
Core Objectives of this TabPage:
- Footprint Area Calculation: Computes total required shipping floor area (sq. meters)
- Zoning Plan: Layout planning for picking, packing, inspection, and staging zones
- Work Throughput Capacity: Calculates hourly shipping throughput capability
- Staffing Plan: Estimates required headcount for picking and packing operations
- Equipment Investment: Determines required equipment counts and system capacities
2. Picking Methodology Adaptability
The Shipping Space TabPage adapts to multiple order picking strategies:
| Picking Strategy | Description | Target Scenario | Space Profile |
|---|---|---|---|
| Single Picking | Picks orders individually line-by-line | B2B, low-volume high-SKU | Aisle-travel focused |
| Batch (Total) Picking | Batch picks multiple orders followed by sorting | B2C, high-volume shipping | Requires sorting buffer area |
| Zone Picking | Divides warehouse into dedicated zone pickers | Large-scale fulfillment centers | Inter-zone transfer space |
| Assort Picking | Gathers items by SKU then sorts by destination | Scheduled route deliveries | Sorting station required |
🖥️ Interface Architecture
Main UI Components
1. Basic Parameters Group
Sets core throughput metrics and picking strategies:
- Daily Outbound Volume: Average daily volume (pieces/cases/orders)
- Peak Factor: Peak-to-average volume multiplier
- Picking Methodology: Single/Total/Zone/Assort selector
- Active SKU Count: Total active item catalog count
2. Detailed Conditions Group
Detailed process parameters per operation stage:
- Picking Parameters: Labor productivity, location density, automation type
- Packing Parameters: Packaging style, workbench count, pack time
- Inspection Parameters: Audit rate, inspection mode, bench space
- Shipping Dock Parameters: Dock bay count, loading cycle time, vehicle size

⚠️ Important Notes & Constraints
1. Data Accuracy & Reliability
⚠️ Garbage In, Garbage Out (GIGO)
Sizing accuracy depends directly on the quality of raw input parameters:
- Outbound Volume Data: Use at least 6–12 months of historical WMS shipment logs.
- Peak Factor: Use 90th or 95th percentile peak ratios rather than single-day anomalies.
- Labor Productivity: Base rates on actual measured engineering time studies.
- Active SKU Count: Incorporate projected business growth for future horizon planning.
