A Petri Net-based Supply Chain System

In order to solve the problem of supply of agricultural products, the current mode of decentralized agricultural product supply is described with the Petri net formalized modeling method. A corresponding Petri net model is established. Based on this, combined with mathematical methods, the supply chain is divided into different links, and a quantitative analysis of the operation cycle and the operational efficiency of each link is carried out. The construction of the program has changed the previous scattered farmer operating model, integrated the information of farmers and related products, and completed the production and processing of agricultural products in the form of task distribution. The circulation of information in the entire supply chain has been realized, thus ensuring the production benefits of each farmer, reducing the previous business risks that a single farmer needs to bear, and improving the operational efficiency of the entire supply chain.
