【摘要】：当前随着全球经济和技术的发展,客户需求日趋多样化,相应的生产制造模式越来越多的转变为多品种、中小批量生产,使得制造过程中生产物流系统的瓶颈大量存在。而占极少数的瓶颈资源是控制生产物流的关键,决定了占大多数的非瓶颈资源的利用程度,只有管理好企业的瓶颈资源才可以优化生产系统的物流和有效产出。因此,生产物流系统瓶颈的诊断和优化研究是提高企业生产效率,降低生产成本,提高设备利用率的重要手段。生产物流系统属于具有高度随机性的复杂离散事件系统,用传统方法分析比较困难。计算机仿真是对真实系统的模仿,能够全面正确的描述有大量随机因素存在的复杂系统,对于分析一般不容易处理的不确定性特别有效。由于WITNESS仿真软件与同类相关软件相比,具有用户界面友好、模型单元丰富、交互式面向对象建模、实时动画显示、输入输出方式灵活、模型柔性好、提供软件间的数据接口、模块化建模、统计性能参数动态显示等优点。因此,本文选择了WITNESS仿真技术和TOC瓶颈约束理论进行结合,以山东弘宇机械有限公司加工车间为实例,来对企业生产物流系统进行研究,重点探讨了生产物流系统瓶颈的诊断和优化技术。本文首先介绍了当前经济和国际背景下对企业生产物流系统进行研究的重要性,分析了生产物流系统的瓶颈诊断和优化的研究现状。其次,对制造业生产物流系统的仿真建模方法进行了初步研究,并介绍了WITNESS仿真软件的功能特点,以及与其他仿真软件对比所具有的优势。再次,从生产物流系统瓶颈的内涵和特点出发,探讨了生产物流系统瓶颈的产生原因,提出了运用仿真技术和TOC技术对系统瓶颈进行诊断、控制和优化的思想方法。最后,以多产品小批量典型制造企业山东弘宇机械有限公司为例,验证了运用计算机仿真和TOC理论对生产物流系统的瓶颈进行诊断和优化的可行性以及优势,从而证明了研究成果的有效性和实用性。
[Abstract]:At present, with the development of global economy and technology, customer demand is becoming more and more diversified, and the corresponding manufacturing mode is becoming more and more multi-variety, medium and small batch production. In the manufacturing process, the bottleneck of production logistics system exists a lot, and the bottleneck resource is the key to control the production logistics, which determines the use of non-bottleneck resources. Only by managing the bottleneck resources of enterprises can the logistics and effective output of production system be optimized. Therefore, the diagnosis and optimization of bottleneck in production logistics system is to improve the production efficiency and reduce the production cost. An important means of improving the utilization rate of equipment. Production logistics system is a complex discrete event system with high randomness. It is difficult to analyze it by traditional method. Computer simulation is the imitation of real system. It is very effective to analyze the uncertainty that is not easy to deal with because the WITNESS simulation software is compared with the similar software because it can describe the complex system with a large number of random factors correctly. It has friendly user interface, rich model unit, interactive object-oriented modeling, real-time animation display, flexible input and output mode, flexible model, data interface between software, modular modeling. Therefore, this paper chooses WITNESS simulation technology and TOC bottleneck constraint theory to combine, taking the processing workshop of Shandong Hongyu Machinery Co., Ltd as an example. This paper mainly discusses the diagnosis and optimization technology of the bottleneck of production logistics system. This paper first introduces the importance of the research on the enterprise production logistics system under the current economic and international background, and analyzes the status quo of the bottleneck diagnosis and optimization of the production logistics system. Secondly, the simulation modeling method of manufacturing production logistics system is studied, and the function characteristics of WITNESS simulation software and the advantages compared with other simulation software are introduced. Thirdly, starting from the connotation and characteristics of the bottleneck of the production logistics system, this paper discusses the causes of the bottleneck of the production logistics system, and puts forward the application of simulation technology and TOC technology to diagnose the bottleneck of the system. The idea of control and optimization. Finally, take Shandong Hongyu Machinery Co., Ltd. as an example. The feasibility and advantage of using computer simulation and TOC theory to diagnose and optimize the bottleneck of production logistics system are verified, which proves the validity and practicability of the research results.
