【摘要】：随着经济的全球化、计算机辅助制造技术和互联网信息技术的飞速发展,企业信息化越来越成为企业关注的焦点。当今中小型企业在信息化浪潮中,为了达到降低管理成本、提高生产效益的目的引入了如ERP、MRP这类信息化管理系统。但是通过调研发现,这些管理系统普遍存在由于底层生产制造信息无法上传到上层管理层,而且上层决策层的管理无法抵达底层生产层,导致生产计划排程始终无法达到最优的状态。而随着企业信息化的进一步发展,MES生产制造执行系统的出现,使得很大一部分由于生产制造信息和管理层的信息不互通而产生的问题得到了很好的解决。同时在产品质量控制层面,中小企的整体质量评价体系都缺乏一套科学合理的指标,往往是借鉴车间工人或相关行业的经验来制定检验指标。这就直接导致产品质量控制会产生很多无用功,而且无法真正实现对产品质量的控制。H公司作为一个小型电子制造企业,顺应市场变化,也引入了ERP系统作为企业信息化管理系统。但是经过此案场实地调研,以上的问题H公司都存在,因此拥有一套与企业具体情况相适应的,兼备拓展性、可靠性、可用性的生产制造执行系统对H公司来说势在必行。本文首先分析了MES系统的国内外发展现状,阐述了MES系统的定义和基本框架。再通过对MES生产制造执行系统的生产管理模式的研究,分析电子制造行业的特点,提出MES生产管理模式对小型电子制造企业的必要性。然后分析H公司目前生产管理中存在的问题,根据H公司实际情况,提出一套基于产品质量控制的MES解决方案。接着基于产品质量控制,通过对统计学的研究,分析目前H公司的产品质量指标评价体系,建模分析并得到一套更能科学合理的反映产品质量的指标体系。在以上理论基础上,结合H公司的生产管理现状和优化的质量评价体系,提出一套基于质量控制的面向小型电子制造企业的个性化MES执行系统解决方案,并对系统进行了设计与实施。
[Abstract]:With the globalization of economy, the rapid development of computer-aided manufacturing technology and Internet information technology, enterprise informatization has become the focus of attention. In order to reduce the cost of management and improve the efficiency of production, small and medium-sized enterprises have introduced such information management systems as ERP MRP in the information tide. However, through the investigation, we found that these management systems generally exist because the manufacturing information of the bottom production can not be uploaded to the upper management level, and the management of the top decision level can not reach the bottom production layer. As a result, the production planning schedule is always unable to reach the optimal state. With the further development of enterprise informatization and the emergence of mes manufacturing execution system, a large part of the problems caused by the lack of communication between manufacturing information and management information have been solved. At the same time, at the level of product quality control, the whole quality evaluation system of small and medium-sized enterprises lacks a set of scientific and reasonable indicators. It is often to draw lessons from the experience of workshop workers or related industries to establish inspection indicators. This will directly lead to product quality control will produce a lot of useless work, and can not really achieve the control of product quality. H company, as a small electronic manufacturing enterprise, adapt to market changes. ERP system is also introduced as enterprise information management system. But through the field investigation of this case, all the above problems exist in H Company, so it is imperative for H Company to have a set of production and manufacturing execution system which is suitable for the specific situation of the enterprise and has both expansibility, reliability and availability. This paper first analyzes the development of MES system at home and abroad, expounds the definition and basic framework of MES system. Through the research on the production management mode of the MES manufacturing execution system, the characteristics of the electronic manufacturing industry are analyzed, and the necessity of the MES production management model for the small electronic manufacturing enterprises is put forward. Then the problems existing in the production management of H Company are analyzed. According to the actual situation of H Company, a set of MES solution based on product quality control is put forward. Then, based on the product quality control, through the research of statistics, this paper analyzes the evaluation system of product quality index of H company, modeling and analyzing, and obtains a set of index system which can reflect the product quality more scientifically and reasonably. On the basis of the above theory, combined with the production management status of H Company and the optimized quality evaluation system, a set of personalized MES execution system solution for small electronic manufacturing enterprises based on quality control is put forward. The system is designed and implemented.
