It is also a network of businesses and business units involved in the process of material acquisition, material processing, and delivery of finished products to users. In the image, we can portray the supply chain as a large, leafy tree: the tree roots of the manufacturing enterprises; the sole agent; the distributors are the branches and treetops; the green leaves of the trees are the end users; Roots and the main rod, branch and pole one by one node, contains a time of circulation, the context of the same body is the information management system.
