According to the general concepts and characteristics of the system we have introduced, and the role and characteristics of logistics in logistics overview, we can see that we must study the logistics activities in a systematic way in order to better play the role of logistics in the national economy. Realize the macroeconomic and microeconomic benefits of logistics activities.

 

The logistics system is composed of various elements of logistics. There are organic links among the elements and a comprehensive body that can rationalize the overall logistics function. The logistics system is a subsystem or component of a large socio-economic system. Specifically, the logistics system refers to the logistics products, packaging equipment, loading and unloading and transporting machinery, transportation tools, storage facilities, transportation roads, circulation processing and waste recycling facilities and other materials that need to be operated in a certain period of time and space. The dynamic elements of interactions, interdependence, and constraints of energy, personnel, and communications networks (information information) include packaging, handling, transportation, storage, storage, distribution processing, waste recycling, and intelligence information collection. The organic whole of the functions of processing, processing, and sorting is in the entire national economic system environment.

 

2. The mode of logistics system

 

In the field of circulation, the logistics process can be seen as a process system in which the various logistics elements, from production to circulation, interact and interdependent. In the production field, the logistics process is a constant investment in raw materials, machinery and equipment, and labor. After processing and processing, the output meets the social needs of the investment and output systems; in terms of every aspect of the logistics process, it is also a vote. People and output systems. Each link must absorb a certain amount of energy, resources (people, money, and goods) from the external environment, and invest in the form of input. After conversion processing, it directly or indirectly produces a certain product or service, and then outputs it. Provided to the outside world to meet certain social needs.

 

Therefore, the logistics system is still a process of constantly losing people from the environment, through conversion processing, and constantly outputting products or services. This is the basic model of the logistics system.
