According to the general concept and characteristics of the system and the role and characteristics of the logistics in the logistics, we can see that the logistics activities must be studied systematically and in order to better play the role of logistics in the national economy, To achieve the macroeconomic and logistics activities of microeconomic efficiency.
Logistics system is composed of elements of the logistics, elements exist between the organic link and the logistics of the overall rationalization of the function of the complex. A logistics system is a subsystem or component of a socio-economic system. Specifically, the logistics system refers to a certain time, space, by the need to run the logistics products, packaging equipment, handling machinery, transport, storage facilities, transport roads, circulation processing and waste recycling facilities and other substances , Energy, personnel and communication network (intelligence information) of a number of interaction, interdependence and constraints of the dynamic elements of the composition, with packaging, handling handling, transportation, storage custody, circulation processing, waste recycling, and intelligence information collection , Processing, finishing and other functions of the organic whole, and in the entire national economic system environment.
2. Logistics system model
In the field of circulation, the logistics process can be seen as a process by the production of circulation to the consumption of the logistics elements of the interaction and interdependence of the process system. In the field of production, the logistics process is a continuous investment in raw materials, machinery and equipment, labor, after processing, output to meet the needs of society investment and output system; on the logistics process in every aspect, the same is a vote Man and output system. Each part of the external environment from the external environment to absorb a certain amount of energy, resources (people, finances, objects), and input in the form of input, through conversion processing, directly or indirectly to produce a certain product or service, and then output To the outside world to meet the needs of a society.
Therefore, the logistics system is still a continuous input from the environment elements, through the conversion process, the continuous output of the product or service cycle process, which is the basic model of the logistics system.
