Research on Cooperative Sharing of Material Purchase Based on Vector Model

In the process of material procurement, the supply chain procurement business involves different software and hardware operations in the network system. In order to reduce the cost of material procurement, the design of material procurement collaborative sharing system based on information flow hierarchy model is proposed. The hierarchical model of material procurement information flow is established to integrate the material procurement information. The data in the supply chain is managed and stored based on the block chain. The hierarchical model is used to describe the flow of information in the basic network, observe the sharing demand, and randomly extract the material procurement information. Finally, the vector model is used to realize the collaborative sharing of material procurement. The experimental results show that it can reduce the cost of material procurement and the time of collaborative sharing, improve the efficiency of material procurement, meet the demand of collaborative sharing of material procurement, and has practical significance.
