【摘要】：流程型制造业是指将原料经过生产设备不间断地的加工,进行一定的化学反应或物理变化,从成份到尺寸最终得到产品的企业。钢铁企业是典型的流程型制造业,上世纪末我国的钢铁企业逐渐实现了客户全球化,客户对钢铁产品的要求也从品种单一多量逐渐趋向小批量多样化,一味追求产量的我国钢铁制造业出现了生产力过剩的现象。为适应日趋激烈的市场竞争,钢铁企业以客户定单为出发点缩短生命周期,匹配多种服务,制造执行已从过去的以产量为中心过渡为以质量为中心。相应,流程型MES系统也应随之改变。近几年来,雾霾天气的出现频率越来越高,尤其在钢铁企业集中的河北省,钢铁企业高炉转炉所排放的烟尘、粉尘等化学污染物是雾霾形成的主要来源,目前国内外的MES系统尚没有把能源也集成到制造执行系统中。MES系统为企业ERP层与PCS建立了很好的信息桥梁,在流程型企业的生产应用中,起到对信息集成承上启下作用,解决了生产过程自动化与企业管理级信息化之间的数据传递问题。它把以客户订单为中心的钢铁企业主要分为了三大功能:计划下发、生产监控、物料跟踪。本次课题将在这三个层面,再结合钢铁生产过程能源流向分析,以一个品种通知单号为切入点,来研究以钢铁企业为例的流程型制造执行系统的架构方法,从排产方法、设计方法、系统开发等层面来阐述关键问题。本文为实践项目,最终给出了一个具体针对某大型钢铁企业的钢后MES系统,基本实现了流程型企业的智能制造与绿色制造。本文主要对生产计划下发过程中的排产方式及生产过程监控模块做深入探讨。
[Abstract]:Process manufacturing refers to the enterprises that process raw materials through continuous processing of production equipment, carry out certain chemical reactions or physical changes, and finally obtain products from composition to size. Iron and steel enterprise is a typical process manufacturing industry. At the end of last century, China's iron and steel enterprises gradually realized customer globalization, and the customer's demand for steel products gradually changed from single variety to small batch diversification. China's iron and steel manufacturing industry, blindly pursuing output, appears the phenomenon of excess productivity. In order to adapt to the increasingly fierce market competition, iron and steel enterprises take customer orders as the starting point to shorten the life cycle, match various services, and manufacture execution has changed from the production as the center to the quality as the center. Accordingly, flow-based MES system should also change with it. In recent years, haze weather has become more and more frequent. Especially in Hebei Province, where iron and steel enterprises are concentrated, chemical pollutants such as dust, dust and other chemical pollutants emitted from converter of iron and steel enterprises are the main sources of haze formation. At present, the MES system at home and abroad has not integrated the energy into the manufacturing execution system. The MES system has built a good information bridge for the enterprise ERP layer and PCS. In the production application of the process enterprise, it plays an important role in information integration. The problem of data transmission between production process automation and enterprise management level informatization is solved. It divides the customer order-centric steel enterprises into three main functions: planning, production monitoring, material tracking. This topic will be in these three levels, combined with the analysis of energy flow in the steel production process, with a variety notice number as the breakthrough point, to study the steel enterprises as an example of the process of manufacturing execution system architecture, from the production scheduling method. Design methods, system development and other levels to explain the key issues. In this paper, a post-steel MES system for a large iron and steel enterprise is presented, and the intelligent manufacturing and green manufacturing of the process enterprise are basically realized. This paper mainly discusses the production scheduling mode and production process monitoring module in the process of production planning.
