【摘要】：随着经济全球化的发展,多品种、小批量及定制化生产模式使得制造企业的生产成本急剧上升,而精益思想的提出为企业带来了希望。精益生产通过消除浪费,从整体上降低了生产成本。然而,完全人工的精益生产管理方式带了了诸多问题,如看板管理困难、纸质单据不统一、库存管理混乱等,标准化作业、一个流、均衡生产等也难以在车间落实。基于制造执行系统(MES)的车间层管理信息系统为精益生产提供了可靠的技术支持,二者在车间层生产管理上可以相互依赖和促进,共同提高生产管理水平。本文通过文献研究、实地调研和行业资料收集的方法,分别研究了精益生产体系以及MES的架构,从理论上总结出二者在车间生产管理中相互支持之处,试图将精益生产工具借助MES更好地应用到车间的生产派工、质量管理、设备管理、物料配送等业务流程中,实现车间生产的精益化。对于面向MES的精益生产是否可行,本文从推拉理念、可视化管理、价值流分析以及持续改善等方面,根据生产计划和过程控制,进行理论和应用层面的深入研究。首先,在生产计划层面,结合MES推式生产原理和精益生产的拉式生产原理,通过对关键节点实行推式生产和非关键节点实行拉式生产,实现生产计划的推拉结合。其次,在生产过程控制层面,通过安灯、电子看板以及触摸屏等可视化工具与MES集成,实现生产派工、物料配送、质量控制的动态管理以及数据的实时收集与反馈。再次,在总体流程层面,由于价值流图涉及多种精益工具的应用,同时包括生产计划与控制全过程,本文将其作为总体流程分析工具。通过研究面向MES的价值流图分析的实现模型,实现车间总体价值流图的实时绘制,及时发现生产过程中的浪费,进行生产、技术和管理层面的持续改善。最后,文章以某柴油机公司机械加工车间为例,以价值流分析为主线,对车间进行定量(增值比)和定性的需求分析,结合实际生产过程对面向MES的精益生产应用进行描述。在基于MES和精益生产的未来价值流的设想下,绘制出价值流未来状态图,作为持续改善的依据。本研究为车间精益管理提供一种新的思路和方法,利用MES来实现车间精益生产的高效执行,提高生产管理效率,实现管理的实时化、可视化和精益化,为正在实施精益生产以及正在利用MES的车间提供管理思想和管理技术融合的参考。
[Abstract]:With the development of economic globalization, many varieties, small batch and customized production mode makes the enterprise manufacturing costs rose sharply, and put forward the lean thinking for the enterprise has brought hope. Lean production through the elimination of waste, reduce the overall cost of production. However, completely artificial lean production management brought many problems, such as Kanban management difficulties, paper documents are not unified, inventory management confusion, standardized operation, a balanced production flow, etc. it is difficult to implement the workshop. Based on the manufacture execution system (MES) provides a reliable technical support for the workshop management information system for lean production, two people can rely on each other and in promoting workshop production management, to improve the level of production management. This article through the literature research, field research methods and data collection industry, lean production system and MES research frame The theoretically summed up the two mutual support in workshop production management, lean production tools with the help of MES trying to be better applied to the workshop production dispatching, quality management, equipment management, material distribution and other business processes, implementation of workshop production lean. The feasibility of lean production for MES this paper, from the push and pull concept, visual management, value stream analysis and continuous improvement and so on, according to the production plan and process control, in-depth study of the theory and application. Firstly, in the production planning level, combined with the principle of push pull type production MES production principle and lean production, through the introduction of push type production and non the key nodes implement pull production of key nodes, realize the push-pull production planning. Secondly, in the production process control level, through an electronic Kanban and lamp, touch screen and other visual tools integrated with MES, To realize the production dispatching, material distribution, real-time collection and feedback of quality control and dynamic management of data. Thirdly, in the overall process level, due to the application of value stream mapping involves a variety of lean tools, including the production plan and control the whole process, will be the overall process analysis tool. The flow graph analysis model through the study of the MES oriented value, real-time rendering of the overall value stream map, discover the waste during the production process, production, continuously improve the technology and management level. Finally, the article based on a diesel engine company of mechanical processing workshop as an example, on the basis of analysis of value flow, quantitative workshop (value added ratio) analysis and qualitative requirements, combined with the actual production process opposite to MES application of lean production are described. Based on MES and lean production future value stream under the idea, draw out the value stream is not To state chart, as a basis for continuous improvement. This research provides a new idea and method for the workshop to achieve the efficient implementation of lean management, lean production workshop by MES, improve the efficiency of production management, real-time management, visualization and lean, as is the implementation of lean production and is using the MES workshop provide management idea and technology integration.
