Abstract: Modern distribution center is a complex logistics system, which is composed of many storage zones and picking zones, and includes many operation patterns with different equipments. Its scientific and rational planning and design are very important to build an efficient distribution center. The needs analysis, capacity planning and the detailed planning syllogism distribution center system planning methodology，the capacity planning model based on the orders data analysis and the equipment allocation model based on storage and picking pattern model are put forward, after doing long-term research on distribution center system planning. The basic storage unit design, the overall capacity planning, storage area planning, process flow designing, and storage area capacity planning based on EIQ-PCB etc are expounded. Finally the application of the methodology in medicine distribution center system planning is introduced.

Key words: Distribution center, EIQ-PCB analysis, Planning, Storage area
