| The market competition in steel enterprises becomes severer. The production looks the tendency of many types and small lots. Products with high quality, low price, timely due time, better services are required. For gaining victory in the competition, the enterprises must implement real-time efficient strategies of production management and guarantee the development with agility, continuity and automation. The enterprises must strengthen production management and the link among different departments, fully use the resources to solve the problems of macro-production disorder because of lack of production planning and chaos of control resulted from dissatisfied scheduling systems.The paper does some research for the described problem.1. Through the research of steel information framework and advanced production management theories such as ERP, MES and JIT etc, the paper presents the advanced steel management mode based on the connection of MRPII and JIT.2. Applying the described production management mode, the paper proposes multi-layer hierarchy strategies of production planning and dynamic scheduling. It builds integrative solution for upper management system ERP and lower execution system.3. Using modeling tool UML, the paper analyzes the system functions, design the system structures and set up the software framework.4. Practicing the software prototype and connecting real conditions and characteristics of the enterprise, the production management system of Dalian Steel Corporation is developed. Based on the advanced management theories and modeling of planning and scheduling, thesystem software satisfies the integration of management and production, obtains the unification of flows of material, capital and information. With the advanced means of modeling, the steel management system is built. The system realizes the optimization of planning and scheduling, shorten the cycle of production, quicken the circulation of capital, decrease cost and obtain the goal of optimal economic benefits. |
