【摘要】：从传统的福特生产方式到丰田精益生产方式,再到基于IT的各种先进制造技术的应用,工业工程的思想无不贯穿于其中。面对我国制造业大而不强的现状,要想改变我国制造业在国际分工中的地位,实现产业升级,企业必须从基础工业工程做起,通过一系列的整合优化,推动生产力的发展。本论文将工业工程基本理论与实践相结合,首先介绍了文章的研究背景、目的。在分析国内外制造企业的应用情况后,指出基础工业工程是我国制造业实现工业化、迈向现代化的必经之路；阐述了工作研究理论中的方法研究和作业测定两大技术,并确定了本研究采用的方法。接着选取市场潜力巨大的环保产品——某型空气过滤器装配线为研究对象,针对该装配线产量难以满足需求的现状,以流程分析为切入点,运用“5W1H”提问法和“ECRS”四技巧提出初步改进方案。在此基础上运用工作研究对装配线作业条件和操作进行标准化,将原有的13道工序细分为48项作业单元,分别进行作业测定,对各工位的操作进行了初步的平整。最后找出制约生产率的瓶颈工序,制定解决方案,并利用启发式方法对新方案进行了搜索平衡。通过平衡前后对比计算,可以看出该生产线产量大幅提高,空闲时间减少、负荷系数提高。实践证明：基础工业工程适合于现阶段我国制造业的技术和管理水平,对提高企业生产率、减少浪费、增加效益效果明显。本文的研究方法具有较强的可操作性,可为从事工业工程的技术人员提供参考借鉴。
[Abstract]:From the traditional Ford production mode to Toyota lean production mode, to the application of various advanced manufacturing technologies based on IT, the idea of industrial engineering runs through it. In the face of the large and weak situation of China's manufacturing industry, in order to change the position of China's manufacturing industry in the international division of labor and realize industrial upgrading, enterprises must start with basic industrial projects and promote the development of productive forces through a series of integration and optimization. This paper combines the basic theory and practice of industrial engineering, first introduces the research background and purpose of the article. After analyzing the application of manufacturing enterprises at home and abroad, it is pointed out that basic industrial engineering is the only way for China's manufacturing industry to realize industrialization and modernization. This paper expounds the two techniques of method research and job measurement in the theory of work research, and determines the methods used in this study. Then, the environmental protection product, a certain type of air filter assembly line, which has great market potential, is selected as the research object. In view of the fact that the output of the assembly line is difficult to meet the demand, the process analysis is taken as the starting point. A preliminary improvement scheme is put forward by using the method of "5W1H" and the four techniques of "ECRS". On this basis, the working conditions and operation of the assembly line are standardized by using the work research. The original 13 processes are divided into 48 operation units, and the operation is measured respectively, and the operation of each station is preliminarily leveled out. Finally, the bottleneck process that restricts productivity is found out, the solution is worked out, and the heuristic method is used to search and balance the new scheme. Through the comparison and calculation before and after balancing, it can be seen that the output of the production line is greatly increased, the idle time is reduced, and the load coefficient is increased. The practice has proved that the basic industrial engineering is suitable for the technical and management level of China's manufacturing industry at the present stage, and has obvious effect on improving the productivity of enterprises, reducing waste and increasing benefits. The research method in this paper has strong maneuverability and can provide reference for technical personnel engaged in industrial engineering.
