With the current state of the global economy, demand for various products plummeting. To sustain in the market, companies have to reduce cost and improve quality. Today, companies have started implementing new philosophies like TQM, TPM, six sigma and lean manufacturing techniques to remain competitive in the market. Lean manufacturing is an emerging philosophy which continuously strives to reduce waste. The main objective of analyzing the assembly line with a lean perspective is to identify the areas related to human interface with other systems that could lead to the generation of waste. Improper workplace design leads to unreasonable mental or physical burden and results in waste generation like slow work (delay and inventory), and defects, which is named as muri waste. An attempt has been made in this paper to locate muri waste and create a "Lean assembly line". The proposed method, based on the use of Rapid Upper Limb Assessment (RULA) with CATIA V5 platform, has allowed the measurement of a large set of operator posture parameters and assessment of ergonomic stresses. Based on the results, the process stations in the assembly line were redesigned to prevent the generation of waste.
鉴于全球经济的现状，各类产品的需求急剧下降。为了在市场中生存，企业必须降低成本并提高质量。如今，企业已开始实施全面质量管理（TQM）、全员生产维护（TPM）、六西格玛和精益制造技术等新的理念，以在市场中保持竞争力。精益制造是一种不断努力减少浪费的新兴理念。从精益的角度分析装配线的主要目的是识别与人类与其他系统交互相关的可能导致浪费产生的区域。不合理的工作场所设计会导致不合理的精神或身体负担，并产生诸如工作缓慢（延误和库存）和缺陷等浪费，这被称为“无理”浪费。本文试图找出“无理”浪费并创建一条“精益装配线”。所提出的方法基于在CATIA V5平台上使用快速上肢评估（RULA），能够测量大量操作员姿势参数并评估人体工程学压力。基于这些结果，对装配线中的工艺工位进行了重新设计，以防止浪费的产生。
