文本描述
近年来,我国汽车市场由一个合资品牌主导时期,进入一个合资品牌及自主 品牌共同发展的时期。蓬勃发展的背后是该产业相对的产能过剩和人员过剩。这 就要求行业供应链进行革新。而精益供应链管理模式,也是基于形势的发展而产 生的,是在制造企业传统运作模式基础上,以制造型及物流企业战略发展为出发 点,促进制造型企业供应商、客户与企业之间较好合作而推出的。同时,精益供 应链管理作为供应链管理中比较关键的环节,通过精益供应链管理,保障业务的 顺利开展,最终实现制造型企业的最终交付。因此,在供应链领域引进精益供应 链管理,对促进制造型企业经营发展具有不可低估的作用。 本文针对精益供应链管理研究内容如下: 现场搬运距离研究:对生产现场所选取生产线和工位进行数据汇总及观察, 围绕现场搬运浪费实际情况进行分析,运用精益工具进行研究。围绕该改进课题, 进行人工搬运和物流设备搬运的减少:其中包括生产线配送物料的包装更改,减 低包装不合理造成的搬运浪费;生产线分包装物料收容数(SNP, Standard Number of Package)和返空流程不合理造成的多次搬运。以及成品传送带传递替代物流 设备搬运的研究。 生产准时化研究:生产准时化(JIT, Just in Time)选取具有代表性的两条 生产线开展研究,识别问题,确认改善的目标。在过程中识别一些尚不清晰的途 径,并且通过 PDCA 循环找到解决办法。并最终达成目标状态。 库存周转率研究:从人机料法环进行分析目前影响库存周转率提升的因素, 主要影响因素为销售额和库存管控:首先解决销售预测准确率,通过汇总和检查 客户周期内预测准确做出相对准确的判定,减少由于销售预测虚高而造成的原材 料订购;而后通过库存管控分级工具进行科学的设置和分类。 关键词:精益供应链,生产准时化(JIT),库存周转率湖 北 工 业 大 学 硕 士 学 位 论 文 2 Abstract In recent years, China's automotive market has been moved from a period dominated by a joint venture brand to joint venture brand and independent brand development period. Behind that is the industry's relative overcapacity and over staffing. This requires innovation in the industrial supply chain. The lean logistics supply chain management model is also based on the development of the situation. It is based on the original operation mode of manufacturing enterprises, and based on the strategic development of the enterprises, it is launched to promote better cooperation between logistics enterprises' suppliers, customers and enterprises. Lean supply chain management, as a key link in the supply chain, guarantees the smooth development of logistics scope, logistics function, logistics subject and other contents through lean logistics management, and finally realizes the integrated supply of the s enterprises. Therefore, the introduction of lean logistics management in the field of supply chain is of great significance to the promotion of logistics and enterprise economic development. The research as below: Research for on-line transportation: Collect and observe the data of the production line and selected object, focus on useless transit with lean tools. Based on the improvement topic, the reduction of manual handling and logistics equipment handling is carried out: including the packaging change of materials distributed on the production line, reducing the handling waste caused by unreasonable packaging; caused by SNP (Standard Number of Package) and empty box return process in the production line. As well as the finished product conveyor belt transfer alternative logistics equipment handling research. Research on just-in-time production: JIT (Just in Time) selects two representative production lines to carry out research, identify problems and confirm the targets. In the process, identify some unclear approaches and find solutions through the PDCA cycle. And then achieve the target. DIO Research: Analyze the factors that influence the improvement of inventory turnover rate from 4M1E(Man, Machine, Material, Method, Environments). The main influence is sales and inventory control. Firstly, solve the accuracy of sales forecast, and make relatively accurate judgment by summarizing and checking the forecast in the period, it can reduce the raw material caused by the high sales forecast. Then the inventory control classification tool is used for scientific setting and classification.
