摘要

目的本研究旨在展示精益六西格玛(LSS)在日本一家不锈钢制造企业的应用，以改善良率。设计/方法/方法采用了由单个描述性案例研究组成的定性方法。我们使用了第一手资料和第二手资料。访谈是由六西格玛团队进行的。此外，还对项目文件进行了深入审查。通过检查表格、事实和数字，解释了“定义、测量、分析、改进和控制(DMAIC)”阶段。公司因材料不良导致的降级率为0.21%。在张力单元、地毯清洗单元、涂层单元、薄膜表面和辊的清洗中发现了根本原因。因此，采取了相应的改进措施。实施LSS后，轧制吞吐率为99.05%，不良率降至0.08%，提供了统计证明的结果，直接反映了客户满意度。原创性/价值据作者所知，这是第一个案例研究，研究了LSS的应用，以提高 rkiye中型不锈钢公司的产量。

Application of lean six sigma for yield improvement in the stainless steel industry: a recipe from Türkiye

Purpose This study aims to demonstrate the application of Lean Six Sigma (LSS) at a stainless steel manufacturer in Türkiye for yield improvement. Design/methodology/approach A qualitative approach consisting of a single descriptive case study was adopted. Both primary and secondary sources were used. The interviews were conducted with the Six Sigma team. In addition, an in-depth review of the project documents was conducted. The “define, measure, analyze, improve and control (DMAIC)” phases were explained by examining the tables, facts and figures. The company’s downgraded rate owing to defective materials was 0.21%. Root causes were detected in the tension unit, carpet cleaning, coating unit, film surface and cleaning of the rolls. Therefore, improvements were taken accordingly. Findings The rolled throughput yield was 99.05%, and the defect rate was reduced to 0.08% after implementing LSS, which provided statistically proven results and a direct reflection on customer satisfaction. Originality/value To the best of the author’s knowledge, this is the first case study examining the application of LSS to improve the yield of a medium-sized stainless steel company in Türkiye.
