Many enterprises have implemented corresponding systems in management and process control, but most of them are “information silos” that are difficult to effectively integrate. Due to the production characteristics of the petrochemical industry, most petrochemical enterprises attach great importance to the construction of process control systems, implementing the Process Control System (PCS) on important equipment and devices, and emphasizing the collection, storage, and organization of real-time data. With the landing and increasing popularity of ERP (Enterprise Resources Planning) in the Chinese market, many enterprises in the petrochemical industry have also implemented corresponding ERP systems, which have been optimized and improved in management. At present, it can be said that management information systems represented by MRP II and ERP, as well as automation technologies represented by distributed control systems (DCS) and fieldbus, have been widely applied in the process manufacturing industry. Although the promotion of these two types of systems has achieved certain results, the effective integration between them has been ignored, resulting in a lack of effective real-time information support for the upper level planning of the enterprise and a lack of optimized scheduling and coordination for the lower level control links. There is no good two-way information flow interaction between the planning layer and the workshop execution layer, making it difficult for enterprises to respond in real-time, hindering the normal functioning of various systems, and also unable to reflect the overall benefits of the information system.
