Abstract

To address the problems of unreasonable functional area configuration and intersecting logistics routes in express transit warehouses, Warehouse F was taken as the research object and the Systematic Layout Planning (SLP) was adopted to optimize its spatial layout. Basic data, including the area of each operating unit, logistics volume, handling distance, and operational relationships, were collected through field observations and interviews. Based on PQRST analysis, logistics and non-logistics relationships among the operating units were established. A weighting ratio of 3:1 was then assigned to the logistics and non-logistics relationships to determine the comprehensive closeness ratings. An activity relationship diagram and a space relationship diagram were designed to generate the optimized layout. The results show that the optimized scheme places highly related operating units in closer spatial proximity, provides a clearer separation between major logistics operating areas and auxiliary functional areas, and reorganizes the main parcel flow into a more continuous and clearly structured process, thereby reducing unnecessary detours and intersections. The optimized layout improves the consistency between the spatial configuration of functional areas and the actual parcel flow process and provides a reference for the layout optimization of similar express transit warehouses.
