摘　　要： 近年来，我国以出口为主的制造业在全球经济不景气，主要出口欧美等发达国家的消费低迷，同时再加上人民币的不断升值，人工成本不断上涨，导致出口利润严重下降，制造业面临着很大的成本压力和生存危机。所以如何提高制造业的核心竞争优势–保证质量，按时，以最少的成本生产出货变为一个非常重要的课题。 本文通过选择以出口欧美高档健身器材的LD公司作为研究对象，通过对比分析在实施精益生产之前和之后的生产效率，旨在说明精益生产体系对于在以客户需求时间节拍（TAKT）的基础上消除八大浪费（不良、修理的浪费，过分加工的浪费，动作的浪费，搬运的浪费，库存的浪费，制造过多过早的浪费，等待的浪费和员工头脑的浪费），对生产效率确有显著的提升。 本文根据LD公司生产线实际情况，依据精益生产理论和工业工程理论，分别从优化生产线布局，改善部分生产线类型，生产流程优化，进行标准作业，提高设备的作业能力，从而全面优化生产线，达到了生产线平衡，提高生产效率，提高生产线产量，缩短了交货周期，降低公司产品生产成本，提高公司产品的利润。 一般来说实施精益系统的过程可分为，首先由VSM价值流程图对LD公司现有多品种小批量生产流程的分析，鉴别出需要重点改善的环节，制定出未来基于客户需求时间节拍的未来VSM价值流程图作为改善目标。其次，使用U型生产线布局理念等方法对生产线进行布局调整。然后，通过作业时间测定，收集生产线的当前各个工位的作业时间，对LD公司生产线当前的平衡率和生产效率进行测定和评定。根据测定的时间安排相关工位，并确保工位之间的作业平衡。与此同时，实施SMED单分钟快速换模。最后在这些活动的基础上进行设备TPM和5S维持。 In recent years, China's export-oriented manufacturing industry is facing huge challengesdue to the economic downtown of Europe and other developed countries. Coupled with thecontinuous appreciation of the yuan and rising labor costs, China endures in a serious declinein export earnings. The Chinese manufacturing industry is facing significant cost pressures. Sohow to improve the core competitiveness of manufacturing-to ensure quality, on timedelivery with minimal production cost become a very important issue. In this paper, by choosing high-end fitness equipments of LD company which are mainlyexported to Europe as the research object, through comparative analysis of theimplementation of lean manufacturing productivity before and after, to illustrate the leanproduction system to customer requirements based on the elimination of eight wastes /(poorquality, rework, over processing, motion waste, waste of handling, inventory waste,excessive manufacturing waste, unnecessary waiting and waste of employee’s talent/), theproduction efficiency significantly indeed improved. Based on the reality of LD company production line, according to the lean productiontheory, and industrial engineering theory, respectively, this paper shows how the Leanpractice improved the production line balance, productivity, output, leadtime, cost reduction,and profits increase, from the perspective of optimization of production line layout,improvement of the production line type, production process optimization, standardoperations, improvement of operational capabilities of the device. Generally the process of implementing lean systems includes–First to analyze theVSM/(Value Stream Mapping/), and identify the waste cycles on the VSM based on thecustomer demand. Secondly, through PQPR /(production flow analysis/), the product family canbe identified based on the process differences. Then use U-shaped production line layout ideasto adjust the layout of the production line. Next, measure the operating time, and arrange workers based o
