Research And Application On Integrated Quality Management System Based On MES

Quality is one of the most important conditions for a company to success in the fierce market competition. Especially for the discrete manufacturing enterprise, whose quality management efficiency is reduced by the mutual independence of the manufacturing process and quality activities because of the discontinuous process. How to improve the quality control ability by integrating the logistics information with the quality information in the manufacturing process is a common issue for the traditional manufacturing enterprises. MES can provide enterprises with the real-time status of materials in the manufacturing process. So the research of the integrated quality management system based on MES has practical and theoretical significance.With an certain enterprise producing wind accelerators as the background, based on the research situation of the integrated quality management system at home and abroad and today's advanced quality management technology and mainstream quality management theories, according to the ERP/MES/PCS structure which is a three-tier model for enterprise integration, the architecture of the integrated management system based on MES is established in this paper. By the investigation and analysis of products and production features, organizational structure and business process of the enterprise, the integration and functional requirements are confirmed, and the functional model of the system is established. According to the analysis and optimization of the current business processes and information flows, the business processes and information models of the quality management system based on MES are established; In view of the requirements of information exchange between production process and quality process, a loosely coupled integration method is proposed and used in the integrated quality management system based on MES; by researching the technology principle of SPC, the SPC flow in the quality management system is established and the detailed design of the functional models of the system are completed. Finally, based on C/S mode, using object-oriented design methods, choosing SQL Server 2000 as the database system, and adopting Visual Basic.NET as the development tool, the integration quality management system is developed and implemented.At present, through the implementation of the system in the enterprise for half a year, the quality management efficiency is improved with improving the interaction efficiency between the manufacturing process and the quality activities. The research in this paper is exemplary for other discrete manufacturing enterprises to apply IT.
