Taking a wide view of the development trends of the process industry in the world, the control and management of the production cost is developing toward informationization for the business-decision. So it drives the enterprises to make full use of modern information technology and advanced cost management theories to decrease the business costs and increase the economic profits. To take the application of MES technology is an important direction of developing，and it takes the role as a bridge of information flow in enterprise. The thesis does some researches as follows: 1. Research on MES function model and data integration technology. Based on the deeply research of MES function model, the first part of the thesis discusses how to build the data model of MES and the manner of data-integration in MES ,then overlooks the technology of SIMATIC IT form SIEMENS, and analyzes the software MFIAS developed by SCIAMPLE which using the MES data integrate model， then introduces an engineering implementation case by using MFIAS. 2. Research on Cost Control Model of Petrochemical Plants’ Producing Process. Petrochemical industry is typical in process industry. The second part of the thesis analyzes the feature of production cost control in petrochemical enterprises, researches the production cost control structure and its control model based on ERP/MES/PCS. Using an example of a fluidized catalytic cracker, it explains how to combine the economic indicators and technical indicators with operation process, and how to upbuild the relation in these indicators and transform the technical indicators into technological parameters which can be controlled in practical application. Such can realize the cost dynamic controlling. 3. Research on chemical cost management system and build the architecture. Coal chemical industry is also a branch of process industry. Based on the researches of chemical industry and its information level and the advanced enterprise management theories such as ERP and MES, this thesis presents the chemical industry oriented production cost management mode in the integrated environment of ERP/MES. According to the production management mode described above, this thesis builds integrated production cost management system based on the execution system. This thesis also analyzes the system functions, designs the system structure, and sets up the system architecture.
