ERP and MES data exchange middleware design
Early in the Mittal Iron and Steel ERP system implementation, with the Mittal Iron and Steel plate - three steel-making production line ME5 project started, in order to MES project smooth implementation of the data exchange between the two is necessary and will be very frequent. If the data transfer between the two is not timely, it will seriously affect the ERP implementation process of decision-making, while the quality of data exchange will affect the MES project implementation. Therefore, the design of a user-friendly data exchange middleware is critical.

System Requirements
Mittal Iron and Steel ERP system to the enterprise logistics, capital flow, and information flow to conduct a comprehensive integrated management. Mittal Iron and Steel ERP system has been implemented in modules, with financial modules, sales module, module manufacturing, quality standards, purchasing module, and equipment module. The main functions MES order to receive and design, process planning and scheduling, quality design, inventory management, data collection, production-line tracking, production reporting, interface management to pay process management. Q pieces of data exchange in the system design is based on, MES system receives the order information on the source of sales orders in the ERP system modules, so the quality of the design orders for standard library data in ERP system, the quality of standard modules, delivery instructions need to ERP systems to MES to do instructions, complete MES can not be shipped to customers, order decomposition, material handling single-processing, invoice generation also need to be completed in the ERP system. At the same time, ERP systems need to process MES systems plan, information on consumption of materials, production and performance into the ERP systems need to warehouses, by-product of information needs into ERP systems. Data Exchange Middleware System not only meets the ERP systems, MES systems are the data needs, the connection layer and the implementation of the enterprise application layer to ensure the logistics, capital flow, information flow and unity, while the fine for head office management, production-to-order manufacturing offers the possibility of change. As users demand for the product personalization Mittal Iron and Steel products are toward the multi-species, the direction of the development of small orders, ERP and MES systems for data exchange between the more frequent, the connection between the two data exchange middleware systems, to meet the customer needs, improve customer satisfaction and enhance the competitiveness of the head office will play a more important role.
