During the circulation of objects, seven functions are needed to support the normal operation of the carrier, including transportation, warehousing, packaging, handling and loading and unloading, circulation processing, distribution, and modern logistics information services. The tacit cooperation between these seven functions enables the operation of this industrial chain to be perfectly displayed, and the user's service experience is greatly improved. However, for customers, they have only personally experienced the preparation before the circulation of objects and the actual situation when the objects arrive at the destination, and do not understand the operation links in the middle. So, when objects are in circulation, which seven functional elements of the logistics system support the normal operation of the circulation of objects?

1. Transportation function. Transportation is one of the core businesses of logistics and an important function of the logistics system. Choosing which means of transportation is of great significance to logistics efficiency. When deciding on the means of transportation, it is necessary to weigh the transportation services and transportation costs required by the transportation system. The service characteristics of the transportation equipment can be used as the basis for judgment: freight, transportation time, frequency, transportation capacity, safety of goods, accuracy of time, applicability, scalability, network and information, etc.

2. Warehousing function. In the logistics system, warehousing and transportation are equally important components. The warehousing function includes a series of activities such as storage, management, storage, maintenance and upkeep of goods entering the logistics system. The role of warehousing is mainly manifested in two aspects: one is to ensure the use value and value of the goods intact, and the other is to store the goods for the necessary processing activities in the logistics center in order to deliver the goods to the users.

3. Packaging function. In order to deliver the goods in the logistics process intact to the users and meet the requirements of users and service objects, most goods need to be packaged in different ways and to different degrees. Packaging is divided into industrial packaging and commodity packaging.

4. Loading and unloading function. Loading and unloading is a necessary logistics activity generated by transportation and storage. It is an intermediate link for connecting logistics activities such as transportation, storage, packaging, circulation processing, and loading and unloading activities for inspection, maintenance and maintenance in storage and other activities, such as loading and unloading, transfer, picking, and classification of goods.

5. Circulation processing function. The circulation processing function is the function of processing and treating goods to make physical or chemical changes in the process of goods flowing from the production field to the consumption field in order to promote product sales, maintain product quality and realize logistics efficiency.

6. Distribution function. Distribution is a special and comprehensive form of activity in logistics, and it is a close combination of business flow and logistics. From the perspective of logistics, distribution includes almost all logistics functional elements, and is a microcosm of logistics or a manifestation of all logistics activities in a small range. Distribution is one of the most important characteristics of modern logistics.

7. Information service function. Modern logistics needs to rely on information technology to ensure the normal operation of the logistics system. The information service function of the logistics system includes planning, forecasting, dynamic (transportation volume, receipt, delivery, inventory) intelligence related to the above functions and related cost intelligence, production intelligence, and market intelligence activities. The management of financial logistics intelligence activities requires the establishment of intelligence systems and intelligence channels, and the correct selection of intelligence subjects and the collection, aggregation, statistics, and use of intelligence to ensure its reliability and timeliness.
