Design And Implementation Of The Workshop Scheduling System For Iron And Steel Enterprises

Iron and steel enterprises as an important force in promoting China's economic growth, its sustainable development is to ensure that the main way of the development of the industry. In the current economic situation, prospects for the development of iron and steel enterprises are facing severe challenges, the individual needs of the market and the product innovation, in the iron and steel enterprises to many varieties, small batch production mode, which put forward higher requirements to enterprise production plan scheduling management. The enterprise informatization as the embodiment of the concept of modern management, management software, the more scientific modern management concept applied to the actual enterprise management process. Manufacturing execution system (Manufacturing Executing System, MES) as the process of enterprise informatization, information system for enterprise top strategic management and lower workshop operation management of fault, in the management and optimization of job shop scheduling, played a good management effect.In this paper, the iron and steel enterprise as background, combined with the MES system, the scheduling function of the system is analyzed and designed. First of all, based on the theory and key techniques are analyzed, the related theoretical basis including the basic connotation of job shop scheduling and evaluation standard, the related technologies including information system development method, system architecture, three layer B/S mode Secondly, the system needs analysis, including system design and objectives, the overall function of scheduling system module, scheduling and management requirements, planning and scheduling requirements, as well as the analysis of the business model, such as steelmaking production scheduling model, scheduling of steelmaking. Finally, design and implementation of the system were studied, the overall framework of the system is mainly to design the overall framework and the technical route, in the realization of system functions, the main task of production and material planning, monthly plan, plan, and has issued the query and maintenance and other aspects of the function analysis.
