Abstract. The internal logistics system planning in distribution center includes: processes planning;
functional area layout planning; facilities and equipment selection configuration; cargo storage
planning. In recent years, China has the unprecedented scale of logistics park construction. In order
to build a scientific and rational logistics infrastructure, it has a very practical value to research the
theory and method of internal logistics system planning in distribution center. From the point of
reality, this paper studies the processes planning, functional area layout planning, facilities and
equipment selection configuration and cargo storage planning. Using the planning methods and
models presented in this paper we can design processes, quantitatively plan facilities in distribution,
improve operational efficiency and reduce operating costs in distribution center.
With the rapid development of economy, the logistics industry has become a pillar industry of
the national economy, playing an increasingly important role in the socio-economic development.
Healthy and orderly development and management of the logistics industry in increasing levels of
society have saved a lot of resources, reducing the cost of commodity circulation. “Logistics is the
third profit source” point of view has been accepted. As one of the most complex network nodes in
the logistics system, distribution center plays an important role in reducing logistics costs. Given
the important role of logistics distribution center in the system, further research and distribution
center logistics system planning methods to achieve a reasonable distribution center layout,
distribution center operations to improve efficiency and reduce logistics costs, logistics and truly
become “the third profit source” has important theoretical and practical significance .
The Concept of Distribution Center
Distribution center is an organization and logistics facilities which received many varieties,
large quantities of goods from the hands of supplier, after the necessary storage and custody, and
then picking, distribution processing, packing, sorting and group information processing and other
operations according to the order requirements of the customer and in the provisions of time the
goods should be delivered to the designated place. Distribution center solves the contradiction
between large quantities of small quantities of specialized production and the diverse needs of users,
is a product of modern logistics development.
The Contents of Distribution Center Planning
The main distribution center is the first organization of business based on customer demand
supply ordering, and then stored custody, picking, distribution processing, packing, sorting, picking
and delivery group. Therefore, the distribution center is to achieve a high level of merchandising
and supply services, modern logistics facilities. Planning and construction of the distribution center
is a complex systems engineering, logistics should be planned from the system planning, operations
management and information systems planning three aspects . The specific planning contents are
as shown in Figure 1.

Fig. 1 The planning of distribution center
Logistics system planning is a planning involving goods circulation. Specifically included.
(1)The processes planning. Distribution center operations carried out according to their own
planning processes, develop scientific and rational processes, improve operational efficiency and
distribution centers. Distribution center processes are the basis for the other layout, especially the
impact on the layout of the functional areas of maximum.
(2)The functional area layout planning. Distribution centers need to determine the functional
areas based on business and job constitutes, according to the job in order workflow layout various
functional areas of science, in order to reduce logistics and transportation distances, reduce logistics
costs and improve operational efficiency.
(3)The machinery equipment configuration. According categories, processes and the degree of
mechanization goods distribution center operated, first select the right type of machinery and
equipment, and then calculate the amount of equipment has a reasonable basis for the amount of
work and mechanical equipment parameters.
(4)The cargo storage planning. General distribution center stocks a large variety, high turnover
rate, reasonable storage of goods distribution center operating efficiency greatly. Therefore, we
should be scientific planning for cargo storage and improve operational efficiency.
The Design Methods of Distribution Center Workflow
Processes is the procedure followed when performed an operation. Distribution center
processes is the operation of the distribution center operations in the order determined by a variety
of operating activities. For the characteristics of the distribution center processes, we use the
modular design approach to design the distribution center workflow. Specific design is shown in

(2)Processes data collection. Master the customer needs of distribution center to determine the
types of goods and operations possible content distribution processing, in order to determine the
(3)Processes.functional partitioning. Processes carried out in accordance with customer
requirements and functional partitioning processes needed to achieve these demands, in order to
determine the processes function modules.
(4)Workflow module.functional analysis. Modules for the proposed formation of functional
analysis process, to see whether it can meet customers’ needs, be adjusted according to actual
situation, until the requirements.
(5)Establish a workflow module. Meet customer needs for functional modules for confirmation,
setting up input and output interfaces.
(6)Module combination. For the establishment of an appropriate combination of functional
modules, arrange the interface design features to achieve docking.
(7)Forming processes. Modules combine to form a distribution center processes .
Distribution Centers Ribbon Layout Planning Methods
Ribbon is the area venues to achieve a particular function. Distribution center is a lot of work
area and it is established in order to achieve logistics and distribution operations. Distribution center
ribbon layout is based on certain principles to determine the relative position of functional areas in
distribution centers, in co-operation with the respective functional areas, to achieve fast and
efficient delivery service.
There are a lot of distribution centers ribbon layout methods and in which the system layout
design (SLP) method is being used more often in recent years.The SLP method has made the plant
layout design developed from qualitative analysis to quantitative calculation, also contributed to the
Facilities Planning widely used in various production and service areas, including distribution
centers, including. SLP method to the product (P), quantity (Q), path (R), ancillary services (S),
time (T) as the basic operational data, analysis and graphical models graphically amount of
introducing the concept of the whole process of design analysis, by introducing the concept to
quantify the relationship between security classification, to build relationships with non-logistics
logistics charts the relationship between the various functional areas, which constitute the
mathematical model area layout design is the main method of layout design. SLP method layout
process is shown in Fig. 3.

Distribution Center Equipment Selection and Configuration Methods
Machinery equipment is also known as logistics technology equipment. It is the general term
for logistics machinery and apparatus in all aspects of logistics activities in use. Distribution centers
to achieve fast and accurate distribution operations to meet customer needs, with the right choice of
machinery and equipment is necessary. AHP can be used in distribution center equipment selection.
AHP (The analytic hierarchy process) is a combination of qualitative and quantitative,
systematic, hierarchical methods for analyzing. Since AHP practicality and effectiveness in dealing
with complex decision problems to a wider range of applications .
Cargo Storage Planning Methods
Distribution centers usually purchase in large quantities and variety of goods, after a short
storage necessary it needs processing operations according to customer orders, and then the goods
reach the customer designated locations. The feature of distribution center storage area is to store
variety, volume. The problem caused by the characteristics is the large demand for storage area and
it is difficult to manage. Distribution center storage area for cargo storage plan will improve the
way the efficiency of warehouse operations and storage area utilization, improve customer service
quality. Cargo storage and distribution center planning include: storage area inside the regional
distribution, storage layout, cargo management planning.
(1)Through in-depth study of the theory and methods in distribution center logistics system
planning, we formed a relatively systematic planning theories and methods in processes planning,
functional area layout planning, machinery equipment configuration and cargo storage plan. And
we provide a theoretical basis for the future distribution center logistics system planning
(2)Logistics is a booming new industry in society and logistics industry will be sustained and
get a much more rapid development driven by the rapid economic development, providing a
guarantee for economic development and became the” third profit source “of national economy.
