Statistical Process Control as a Tool for Quality Improvement A Case Study in Denim Pant Production

In this paper, we show that concept of Statistical Process Control tools was thoroughly examined and the definitions of quality control concepts were presented. This is significant because of it is anticipated that this study will contribute to the literature as an exemplary application that demonstrates the role of statistical process control (SPC) tools in quality improvement in the evaluation and decision-making phase. This is significant because of this study is to investigate applications of quality control, to clarify statistical control methods and problem-solving procedures, to generate proposals for problem-solving approaches, and to disseminate improvement studies in the ready-to-wear industry. The basic Statistical Process Control tools used in the study, the most repetitive faults were detected and these faults were divided into sub-headings for more detailed analysis. In this way, it was tried to prevent the repetition of faults by going down to the root causes of any detected fault. With this different perspective, it is expected that the study will contribute to other fields. We give consent for the publication of identifiable details, which can include photograph(s) and case history and details within the text (“Material”) to be published in the Journal of Quality Technology. We confirm that have seen and been given the opportunity to read both the Material and the Article (as attached) to be published by Taylor & Francis.

本文全面检视了统计过程控制（Statistical Process Control，SPC）工具的相关概念，并阐述了质量控制相关概念的定义。本研究具有重要价值，其可作为一项示范性应用，为相关学术文献贡献研究成果，阐明统计过程控制工具在质量改进的评估与决策阶段所发挥的作用。本研究旨在探究质量控制的应用场景，厘清统计控制方法与问题解决流程，为问题解决路径提出改进建议，并在成衣行业推广质量改进相关研究成果。研究中，我们针对所使用的基础统计过程控制工具，检测出最频发的质量缺陷，并将这些缺陷划分为若干子项以开展更细致的分析。通过追溯所检出缺陷的根本成因，旨在避免同类缺陷再次发生。本研究采用这一独特视角，有望为其他领域的相关研究提供参考。作者同意将可识别细节（包括文本中的照片、病例史及相关内容，统称为"研究材料"）发表于《质量技术杂志》（Journal of Quality Technology）。作者确认已审阅并获阅读机会，可通读拟由泰勒弗朗西斯（Taylor & Francis）出版的研究材料与正文（如附件所示）。
