Iron and steel enterprise production logistics information organization method based on PM chain

Provided is an iron and steel enterprise production logistics information organization method based on PM chain which belongs to the technical field of flow industrial informatization. First decomposing a production process into several processes; then recording a process instance during the production of the process; combining a material instance as a feed and a process instance into a link of the PM chain; recording the output as a material instance and combining it with the process instance as a link of the PM chain; at the same time, deducting feeding material in a current stock table andadding output material. When the whole flow information is organized according to the scheme, a complete logistics chain and a synchronously changed current stock table are obtained. The advantage lies in that the information flow of the production process is realized before and after, and the stock information is synchronously generated using the organization method, which lays a foundation for production management, log
