Section 10 Logistics Space Summary

This document explains the "Logistics Space Summary" process—the final stage of distribution center design—consolidating individual area footprints and executing adjustments matching real-world operations.

Rather than simply summing up areas calculated in preceding sections, incorporating space sharing opportunities and auxiliary equipment zones derives realistic and efficient baseline parameters for building specification modeling.

1. Consolidation and Adjustment of All Logistics Spaces

Aggregation covers the following 5 primary functional zones:

After summarizing each zone individually, floor area reductions via "Space Sharing" are evaluated considering operational time-window overlaps.

2. Optimization via Space Sharing

Re-using functional floor areas for secondary purposes during time windows when primary tasks are inactive allows suppressing total building gross floor area.

3. Additional Required Functional Spaces

Essential operational zones omitted from individual section calculations are added to overall space totals:

4. Omitted Items Requiring Planning Review

In practical implementation, the following items must be verified for statutory compliance and environmental considerations:

Utilizing Logistics Space Summary Results

Final summary figures calculated in this step serve as baseline input values for "Building Specification Settings".

Subsection 1 Total Logistics Space Floor Area and Area Adjustments

Logistics space area aggregates shipping space area, receiving space area, outbound work space area, storage space area, and office/welfare space area independently. These areas can be shared during off-peak hours or through operational ingenuity. Spaces where sharing enables floor area reductions are receiving and case sorting.
Additionally, required spaces that must be added to above calculations include packaging material storage and main traffic aisles.

Subsection 2 Receiving Space Sharing

Normally, inbound receiving volume concentrates during morning hours prior to shipping. If shipping space can be 100% utilized as receiving space during morning 60% receiving volume peaks, receiving space loading is reduced by 60%. While area calculations involve other parameters preventing a simple 60% net reduction, overall area reduction is guaranteed.
Although space sharing calculations are not built into default Tera Settings, evaluation is strongly encouraged.

Subsection 3 Case Sorting Space Sharing

Case sorting operations naturally run continuously with bulk retrieval from storage space. Case shipping involves high volume, yet shipping staging areas remain empty prior to sorting; portions of main aisles exhibit low traffic frequency; handling aisles within storage space offer low-use zones; as long as staging sits along traffic flow lines from storage to shipping, dispersing sorting zones does not degrade operational efficiency. Factors permitting space sharing between sorting and other zones exist.
Although space sharing calculations are not built into default Tera Settings, evaluation is strongly encouraged.

Subsection 4 Packaging Material & Auxiliary Supply Storage Area

Covers shipping cardboard boxes, packing tapes, unprinted shipping labels, and various administrative forms.
Because shipping cardboard storage occupies substantial space, cardboard shipping volume (used in piece shipping) represents the primary area determinant. Default Tera Settings calculate 20 PL slots (2% of storage PL capacity) for a 1,000 PL storage warehouse.

Subsection 5 Main Traffic Aisle Configuration

When receiving space and storage space are non-adjacent, or when storage space and outbound work space are non-adjacent, primary transport corridors are required.
Tera Settings calculate 4 m × width dimensions of the distribution center, but a rule-of-thumb guideline assumes 50% of prior calculated area totals.

Subsection 5 Logistics Space Summary

Logistics space summaries factoring in final space adjustments and main traffic aisles serve as foundational baseline input values for building specification modeling.
