We can describe the supply chain as a big tree with luxuriant branches and leaves: the production enterprises constitute the root; the exclusive agent is the trunk; the distributors are the branches and the treetops; the green leaves and safflower covered with trees are the end users; the nodes between the roots and the trunk, the branches and the trunks contain the circulation again and again, and the interlinked vein is the information management system.
The relationship among enterprises in the supply chain is similar to the food chain in biology. In the simple food chain of "grass rabbit wolf lion" (for the convenience of discussion, assuming that only these four living things exist in this natural environment), if we kill all the rabbits, then the grass will grow up, the wolf will starve to death because of the extinction of the rabbit, and even the most powerful lion will slowly starve to death due to the death of the wolf. It can be seen that every living creature in the food chain is interdependent. Destroying any living creature in the food chain will inevitably lead to the imbalance of the food chain and eventually destroy the ecological environment on which human beings depend for survival.
Similarly, in the supply chain "enterprise a - enterprise B - enterprise C", enterprise a is the raw material supplier of enterprise B, and enterprise C is the product seller of enterprise B. If enterprise B ignores the interdependence of various elements in the supply chain, and pays too much attention to its internal development, and its ability to produce products continues to improve, but if enterprise a fails to provide it with raw materials for production in time, or if the sales capacity of enterprise C cannot keep up with the development of production capacity of enterprise B, then we can draw the following conclusion: the development of productivity of enterprise B is not suitable The overall efficiency of this supply chain should be considered.
Note: "value chain" is the same concept as supply chain. There is also the so-called global operations research management, which is actually connected with the supply chain and covers the same scope.
The national standard logistics terminology defines it as the network chain structure formed by upstream and downstream enterprises that provide products or services to end users in the process of production and circulation.
With the continuous iteration of 3G, 4G and even 5g mobile networks, supply chain has entered the mobile era. Mobile supply chain is the technology of using wireless network to realize supply chain. It migrates the customer relationship management function from the original supply chain system to mobile phone. Mobile supply chain system has incomparable advantages compared with traditional supply chain system. Mobile supply chain system enables business to get rid of time and place limitations, communicate with the company business platform anytime and anywhere, effectively improve management efficiency and promote enterprise efficiency growth. The mobile supply chain system of digital star is a mobile supply chain product integrating 3G mobile technology, intelligent mobile terminal, VPN, identity authentication, geographic information system (GIS), WebService, business intelligence and other technologies.
Supply chain in express service, express service has become an indispensable "supply chain" of e-commerce. Every single commodity depends on the delivery of express business to complete the "door-to-door" service.
