【摘要】：随着市场竞争的日趋激烈，为满足客户的个性化需求，制造业从面向库存的生产方式转变为面向订单的生产方式。在该方式下，生产部门如何满足订单按时按量的交货成为企业处于市场不败的关键，为此，越来越多的企业选择了使用信息化管理系统。本文针对当前企业应用ERP管理系统时常见的数据输入瓶颈，生产活动实时信息的缺失，而产生的资源配置不合理，生产管理不到位，订单执行周期长等现象，提出了一套基于RFID的制造执行系统理念，实现了数据录入的智能化，生产信息的透明化，生产控制的实时化，达到了生产过程的彻底的信息化管理。依据制造执行系统现有功能模型，结合企业实际所需，设计了基于RFID技术的制造执行系统总体结构，，重点研究了数据采集和处理方法，详细分析和设计了系统数据库，同时对系统各主要功能模块进行了详细设计。由于企业生产过程的特殊性，本文重点研究和解决了以下问题：（1）制造执行系统的数据采集技术。由于生产数据的分散性和并发性，研究了采集数据的数据终端的分布特点、通讯集成技术，与数据库的互动模式等。（2）数据匹配模式。设计了与ERP的接口标准，数据可以从不同的ERP层级实现集成，本MES的数据可以反写入ERP的相关数据表，并生成符合企业要求的数据报表。（3）现场作业计划的生成。根据周提货单，随时修改生产数量，将相关需求联动修改；由订单生成车间作业计划，进行计划的自动预排，自动安排每道工序的开工和完工时间。（4）现场作业的处理。本系统根据企业的要求，可以进行分批、改制、返修等作业处理，可以实现无缝的订单跟踪，每道作业可以在任意加工数量和工步停止，而不会丢失标识、物料的数据对应关系。（5）现场的质量管理功能的实现，以及数据的现场录入。可以在现场数据终端上查看检验要求，记录质量数据。系统目前已在企业实施，明显改善了车间的黑箱管理现象，提高了企业按时交付能力。
[Abstract]:With the increasingly fierce competition in the market, in order to meet the individual needs of customers, the manufacturing industry has changed from inventory oriented production to order oriented production. In this way, how the production departments meet the orders on time and according to the quantity of delivery has become the key of the enterprise in the market. Therefore, more and more enterprises choose to use information management system. This paper aims at the common bottleneck of data input in the application of ERP management system, the lack of real-time information of production activities, the unreasonable allocation of resources, the lack of production management, the long execution period of orders, and so on. A set of manufacturing execution system based on RFID is put forward, which realizes the intelligence of data input, the transparency of production information, the real-time of production control, and the complete information management of production process. According to the existing functional model of the manufacturing execution system and the actual needs of the enterprise, the overall structure of the manufacturing execution system based on RFID technology is designed. The methods of data acquisition and processing are studied, and the database of the system is analyzed and designed in detail. At the same time, the main functional modules of the system are designed in detail. Because of the particularity of enterprise production process, this paper focuses on the following problems: (1) data acquisition technology of manufacturing execution system. Due to the dispersion and concurrency of the production data, the distribution characteristics of the data terminal, the communication integration technology, the interactive mode with the database and so on are studied. (2) the data matching mode. The interface standard with ERP is designed. The data can be integrated from different levels of ERP. The data of this mes can be written back into the relevant data tables of ERP and generate data reports that meet the requirements of enterprises. (3) the generation of field job plan. According to the weekly bill of lading, modify the production quantity at any time, modify the related demand; generate the workshop work plan by order, carry on the automatic pre-scheduling of the plan, Arrange the start and finish time of each working procedure automatically. (4) processing of site operation. According to the requirements of the enterprise, the system can be processed in batches, restructuring, rework, and so on. It can realize seamless order tracking, and each job can be stopped at any processing quantity and step without losing the mark. Material data correspondence. (5) the realization of site quality management function, and the field data input. You can view the inspection requirements and record the quality data at the site data terminal. At present, the system has been implemented in the enterprise, which has obviously improved the black box management phenomenon in the workshop and improved the enterprise's ability to deliver on time.
