Process automation and the ERP is needed between MES
ERP in the steel industry, for the product is very detailed description of the project there must be a variety of finished and semi-finished features, attributes description. The production process there are many uncertain factors, we must control the entire process. Although iron and steel industry basically the foundation for automation and process automation, but they are the core of a modular production facilities for the detection and control, production equipment lack of information resources sharing and unified management of the production process. The ERP system itself is difficult to connect with basic automated systems can not automatically manage the production data. These management information systems management plans and decision-making during production analysis, production and operation enterprises rely heavily on the actual data generated in the process. To facilitate the ERP system is running, the actual operation had to be a lot of production data to pass through the paper reports, and then input into the management information system. However, this method of data transmission error-prone, low efficiency, the data obtained from lagging behind the actual production, thus affecting the effectiveness of the underlying data, resulting in timely and accurate management information system could not be related to the production and operation of processing and decision making.
MES through the transmission of messages right from the production orders issued to the product done to optimize the management of the entire production process. When the real-time event occurs MES timely response to these events, reports, and use accurate data on their current constraints and processing.
MES functions
Role as a bridge
MES process-model as the core, connect real-time database or non-real-time relational database, the production process in real-time monitoring, diagnosis and control, completion of the integration and system optimization in the production process layer material balance, arrange for production planning, implementation scheduling , scheduling and optimization. Then the production process material flow, energy flow, mass flow, capital flow and data flow full monitoring, analysis, control and optimization.
Iron and steel metallurgical industry, the type of material presented dumbbell-style feature, namely that many different types of inputs of raw materials, intermediate products such as molten iron, steel, billet type of small, but after rolling, and other after-processing and later translated into many different specifications finished product. To achieve efficient production and ensure the correct quantity and quality of qualified, in the required time and with minimum cost according to the customer orders for the organization process, the need for an area to the entire production, including planning, real-time monitoring, the actual results oriented orders, as well as various factors such as material inventory data integration system. The system can improve the transparency of integrated production workflow, enhance productivity and cost efficiency, and optimize the use of equipment, while the MES system will have this feature, which can play up and down to communicate business management platform and on-site control equipment vertically integrated role, since the same time linking all the production lines and realize the whole process of integration of product and quality of design, planning and logistics scheduling, production control and management of the central role in the production of business process automation system and management information systems as a bridge between.
ERP system needs to provide MES cost, manufacturing cycle time and expected outputs the actual production data; ERP were obtained from the MES to the production orders for the actual state of the enterprise's current actual production capacity as well as businesses shift production of the mutual binding relationship; Customer The success of the relationship management module offers and on-time delivery of production decisions at each moment of the actual situation, so it must be closely linked MES; process control need to be based MES products to optimize the process parameters; while basic control module must be from the MES were obtained from the control data or steps. |
