In Mes Steel Enterprise Production Planning Management System

China manufacturing compared with developed country, has several disadvantages, such as technology and equipment lagging behind, product frame unreasonable, product process with poor quality and high costs, and advanced management mechanism scarce, so lack of competitiveness in the world. The word economy is coming in the direction of integrating, the company of China should improve product quality and research advanced technology, at the same time it will satisfy enterprise goal that profit maximize. Then this could guarantee the renewal of the equipment, the cultivation of talent and so on. The enterprise obtains the larger profit, which depended on the advanced management, production planning management system based on MES (Manufacturing Execution Systems) theory, is an important part in the whole management system. It can join with upper planning such as ERP, obtain the information from it and realize it. It draws the running state of the factory automation equipment and send out the control order downwards. It can make the production planning of every day concretely according to the long-term plan, follow the material in process in real time, control the production process, make a response to the accidental event in time, restrain and dealt with them with the present accurate data. These guaranteed production in order.The flow industry is a basic one and occupies the important position in the whole industrial system. It mainly deals with continuous or intermittent material flow and energy flow. Products are usually made in form of large lots. The special steel industry belongs to the flow industry. It has the general character, and has its individuality as product changeable and market changeable.The thesis is to the characteristic of the special steel industry, regard MES as the theoretical foundation, proceed from development practice of the system, and propose the solution against the production planning management system of the special steel industry. Take Liaoning special steel group as an example, has analyzed to the structure and characteristic of the system, use the J2EE enterprise solution to finish the enterprise software system with B/S mode. The implementation of this system speeds the popularization of the enterprise informationization.The production planning management system is difficult to develop. But if can develop suitable to enterprise, it will produce the enormous economic benefits. This system is set up on the foundation of detail research, customize according to the actual requirement of the enterprise, having solved the practical problems effectively, the system is in test run stage at present, the enterprise reacts well. This system framework and solution has reference function to the other same type enterprise.
