Manufacturing enterprises how to construct the logistics system

1, the logistics system is divided into logistics operation system and logistics information system, although the two can be run separately and independently, but also closely linked, interdependent, inseparable. Logistics operations system in the center of the logistics center (or distribution center); logistics information system in the center of the company (or information center).

2, logistics operations system by the transportation, storage, packaging, handling, recycling, circulation and processing of six subsystems in one or more organic combination, each subsystem can be divided into smaller subsystems according to space and time.

Transportation can be divided into two categories:

Direct transportation: from the production plant to the user or distribution center of the transport, long-distance, large-volume rapid transport, the pursuit of improving transport efficiency, generally by train and ship.

Transit transport: from the production plant through the distribution center to the user or retail store transport, according to the nature of the transport is divided into two segments:

Conveyor: from the production plant to the distribution center of the long-distance large-volume rapid transport, the pursuit of transport efficiency.

Distribution: the so-called distribution, is in the material transit transport from the distribution center to the user or retail store transport. Distribution and general transportation is different, the main pursuit of on-time and in accordance with the amount of complete matching for the demand point of timely delivery, generally by car in the neighborhood of the multi-user cycle between delivery, pay attention to good service and do not pollute the environment. The difference between it and conveyance is shown in Table 2-2:

Table 2-2 Comparison of Distribution and Conveyance

Conveyance Distribution

1 Starting point Manufacturing plant to the distribution center or user Distribution center to the user or retail store

2.Characteristics Long distance, high volume and rapid transportation Local area of short and small batches of road cycle delivery

3. Generally automobile

4. Pursuit of the goal of more loads and fast running, improve the efficiency of transportation, on time, according to the amount of timely delivery, good service without pollution and save trips

3, logistics information system: is the generation of logistics information between the logistics network, production, processing, storage and transmission of the system. All logistics outlets at the same time and logistics information network points, plus the company or information center, it constitutes a logistics information system network. The transmission of information is mutual.

4, the characteristics of the logistics system: the material for the object of work, for the purpose of completing the physical circulation of materials.

5, the environment of the logistics system, input, output, constraints and modes:

The environment of the logistics system is the larger system in which the logistics system is located. It is the external conditions that the logistics system deals with, conditions that the logistics system accepts willingly or unwillingly. The interaction between the logistics system and its environment is specifically characterized by inputs, outputs, constraints and disturbances of the logistics system.

The input of the logistics system is the direct input of the environment to the logistics system, which is material and information, and it is the object of the logistics system.

The output of the logistics system is the direct output of the logistics system to the environment, which is also material and information, but it is material and information added to the logistics service. It is the result of the logistics system processing.

The constraints of the logistics system are the indirect inputs of the environment to the logistics system, including materials, information, energy, and political, economic, cultural, geographic and climatic conditions such as software and hardware. They are the external conditions that the logistics system deals with.

Interference, on the other hand, is an accidental constraint.

Model of the logistics system:

6, the goal of the logistics system:

1) good service:

2) cost savings:

In actual operation, the two are often contradictory. To learn to take the compromise. Such as:

Good service and cost savings compromise;

Local and global compromise.
