Introduction to supply chain:
1, refers to the core enterprise, starting from the supporting parts, making intermediate products and final products, and finally delivering the products to consumers through the sales network, connecting suppliers, manufacturers, distributors and end users as a whole. The business philosophy of supply chain management is to seek the overall optimization of supply chain from the perspective of consumers through cooperation between enterprises. Successful supply chain management can coordinate and integrate all activities in the supply chain, and eventually become a seamless integration process.
2. The concept of supply chain is developed from the concept of expanding production, which expands and delays the production activities of enterprises. In the lean cooperation mode of Toyota in Japan, the activities of suppliers are regarded as an organic part of production activities and are controlled and coordinated. Harrison defines the supply chain as: "Supply chain is a functional network that buys raw materials, transforms them into intermediate products and finished products, and sells the finished products to users." Stevens of the United States believes: "Controlling the flow from suppliers to users through value-added processes and distribution channels is a supply chain, which starts from the source of supply and ends at the consumer end." Therefore, the supply chain is the interface between customers and suppliers through planning, acquisition, storage, distribution and service, so that enterprises can meet the needs of internal and external customers.
3. We can describe the supply chain as a tree with luxuriant branches and leaves: production enterprises form roots; The sole agent is the backbone; Distributors are branches and treetops; The tree is full of green leaves and safflower, which is the end user; On the nodes of root and trunk, branch and trunk, the common thread is information management system, which circulates again and again.
4. The relationship between enterprises in the supply chain is similar to the food chain in biology. In such a simple food chain as "grass-rabbit-wolf-lion" (for convenience of discussion, it is assumed that there are only four kinds of creatures in this natural environment), if we kill all the rabbits, the grass will grow wildly, the wolf will starve to death because of the extinction of the rabbits, and even the most powerful lion will slowly starve to death because of the death of the wolf. It can be seen that every creature in the food chain is interdependent, and destroying any creature in the food chain will inevitably lead to the imbalance of this food chain and eventually destroy the ecological environment on which human beings depend.
