【摘要】：造纸术作为我国古代四大发明之一,从出现至今已经有一千八百多年的历史,纸张的发明对人类交流思想、传播文化、发展科技起到不可估量的作用。近年来,随着科学技术的迅速发展,造纸工业受到了严重冲击,造纸企业不仅要面对国内同行业激烈的竞争,而且还要面对国外先进造纸大国的产品冲击;除此之外,造纸成本与日俱增,造纸企业迫切需要进行生产流程优化,提高生产效率和产品质量、降低生产成本和库存,从而提升造纸企业市场竞争力。本文选取MZ纸业公司自动化水平较高、产品种类相对丰富、最具代表性的造纸车间为研究对象,研究成果可以广泛应用于其他造纸车间;因此,对该车间进行生产流程优化可以反映整个公司生产流程优化情况。首先,通过秒表法对造纸车间各工位进行作业测定,然后运用工序分析法对车间现有生产流程进行平衡分析,识别出生产流程的瓶颈工序,然后运用Vensim系统动力学仿真软件对瓶颈工序进行因果分析、模型构建和仿真,运用ABC分类法对库存管理进行优化,运用Flexsim仿真软件对车间布局进行优化,构建瓶颈工序和车间布局仿真模型。其次,根据设计的方案对瓶颈工序进行工序、工艺和工位的改进;通过建立信息平台、ABC分类管理以及看板管理等对库存管理进行优化;通过对设备布局、物料搬运路径和人员移动路线的优化对车间布局进行改善;然后对优化后的生产流程进行二次作业测定和平衡分析。最后,对比分析生产流程优化前后的改善效果,然后针对性提出保障措施。通过本文的研究,不仅可以取消造纸车间不必要的工作环节和内容、合并不必要的工作、重排不合理程序、简化所必须的工作环节,而且能够为企业进行大规模的生产线优化和自动化设计提供研究方法;也为工作人员进行生产线布局优化设计和生产线平衡分析等提供研究思路。方案实施后可以帮助企业实现减员增效、增加收益、提升产品质量和管理水平的目的。
[Abstract]:As one of the four great inventions in ancient China, papermaking has a history of more than 1,800 years since its emergence. The invention of paper has played an inestimable role in the exchange of ideas, the dissemination of culture, and the development of science and technology. With the rapid development of science and technology, the paper industry has been seriously impacted. Paper enterprises not only have to face the fierce competition in the same industry at home, but also face the impact of foreign advanced paper-making countries. With the increasing cost of papermaking, papermaking enterprises urgently need to optimize the production process, improve production efficiency and product quality, reduce production costs and inventory. In order to enhance the market competitiveness of papermaking enterprises, this paper selects MZ Paper Company as the research object, which has high automation level, relatively rich product types and the most representative papermaking workshop. The research results can be widely used in other paper mills. The optimization of the production process of the workshop can reflect the whole company's production process optimization. First, the stopwatch method is used to measure the work of each station in the papermaking workshop, and then the process analysis method is used to analyze the balance of the existing production process in the workshop. The bottleneck process of production process is identified, and then the causality analysis of bottleneck process is carried out by using Vensim system dynamics simulation software, the model is constructed and simulated, and the inventory management is optimized by ABC classification. The Flexsim simulation software is used to optimize the layout of the workshop, and the simulation model of bottleneck procedure and workshop layout is constructed. Secondly, the process, process and work station are improved according to the design scheme. The inventory management is optimized by establishing the information platform ABC classification management and Kanban management, and the workshop layout is improved by optimizing the equipment layout, material handling path and personnel movement route. Finally, the improvement effect before and after the optimization of the production process is compared and analyzed, and then the safeguard measures are put forward. Not only can we eliminate unnecessary work links and contents in papermaking workshops, merge unnecessary work, rearrange unreasonable procedures, and simplify the necessary work links. Moreover, it can provide research methods for large-scale production line optimization and automation design. It also provides research ideas for the staff to optimize the layout of production line and analyze the balance of production line. The implementation of the scheme can help enterprises to achieve the purpose of reducing staff and increasing profits and improving product quality and management level.
