The production line design and manufacturing facilities planning based on Cell production Abstract With the rapid development of economic, most orders of the assembly line enterprises are more varieties and small batch, which makes companies need to have high flexibility and rapid response of the market demand. Cell production have the characteristic of flexibility and efficiency, which has being applied to more and more assembly-oriented enterprises. The paper take the carburetor assembly line as a background, designing and simulating the production site in the laboratory. By analyzing preliminary data and researching, the feasibility of the implementation of Cell production in the enterprise is analyzed. Based on the feasibility, the paper using the priority matrix search method for process synchronization, in order to determine the final number of work places and work load. Using SPL to layout and developing a planning scheme to meet with principles of personnel operation and economic. Finally, contrasting the mode of Cell production and the traditional assembly line production, explaining the advantages of production units, which provides reference for cell production in the implementation of the enterprises.

基于单元制造的生产线设计与设施规划 1 引言 本节结合企业生产实际，从选题背景及意义，国内外研究动态，研究内容和技术路线出发，重点阐述企业实施单元生产的必要性，单元生产线的设计及设施规划布局。 1.1 选题背景 随着经济的快速发展，市场需求逐渐趋于个性化、多样化，因此多品种、小批量的企业生产模式逐渐成为主流。单元生产方式具有柔性与效率兼顾的特点，是精益生产的一个模块，是非常有效的一种生产组织模式。本文在对 5家企业实际调研及查阅相关文献分析及总结后发现，如果生产组织方式选择不当或设施规划不合理，会导致企业生产成本增加，生产周期增加，无法按时交货，造成客户的流失的现象发生。本文以宁波可瑞迪化油器生产公司为例，调研发现近几年，随着企业规模的不断扩大，企业仍旧采用传统流水线，并沿用之前生产线的布局模式，企业订单呈多品种、小批量，传统流水线生产模式的应用导致企业在频繁转线等过程中造成了大量的人力资源及时间浪费。因此，企业如何选择一个适合的生产组织方式成为亟待解决的问题。通过实验室对卡瑞迪生产现场进行模拟发现问题并提出不断改善方案，为企业实施单元生产提供了一定的理论参考。
