Abstract

Bu çalışmada, kalite ve kalite kontrol kavramlarının tanımları yapıldıktan sonra istatistiksel proses kontrol araçları kavramı etraflıca irdelenmiştir. Ardından, hazır giyim sektöründe faaliyet gösteren bir tekstil firmasında üretilen denim pantolonlardan elde edilen veriler sonucunda hataların analizleri, istatistiksel proses kontrol teknikleri ile yapılmıştır. Çalışmada akış şemaları, kontrol şemaları, pareto analizi, kontrol şemaları, neden-sonuç diyagramı ve gruplama tekniği kullanılmıştır. Temel istatistiksel proses kontrol araçlarının kullanılmasıyla, en çok tekrar eden hatalar tespit edilmiş ve bu hatalar daha detaylı analiz için alt başlıklara ayrılmıştır. Bu sayede tespit edilen hataların kök nedenlerine inilerek hataların tekrarı engellenmeye çalışılmıştır. Üretim sırasında oluşabilecek olası hataların nedenleri ve çözüm önerileri kategorize edilmiştir. Tespit edilen hatanın temel nedenlerine inilerek ve kategorize edilmiş, çözüm önerileri sunulması ve uygulanması ile hataların önüne geçilmiştir. Bu farklı bakış açısı ile çalışmanın sektöre ve ilgili alanlara alternatif bir yöntem olarak örnek olması beklenmektedir. Bu çalışmanın amacı, hazır giyim sektöründe kalite kontrol uygulamalarını incelemek, istatistiksel kontrol yöntemleri ve problem çözme prosedürlerine katkı sağlamak, problem çözme yaklaşımları için öneriler üretmek ve iyileştirme çalışmalarını yaygınlaştırmaktır.

Abstract

In this study, after defining the concepts of quality and quality control, the concept of statistical process control tools is examined. As a result of the data obtained from denim pants produced by a textile company operating in the ready-to-wear sector, defects were analyzed using statistical process control techniques. In this study, flowchart, control charts, pareto analysis, p-control diagram, cause-effect diagram, and grouping techniques were used. With the use of basic statistical process control tools, the most recurring defects were, and these defects were divided into subheadings for more detailed analysis. In this way, it was tried to prevent the repetition of defects by going down to the root causes of the detected defects. The causes of possible defects that may occur during production and solution suggestions were categorized. By going down to the basic causes of the detected defects and categorized them, defects were prevented by presenting and implementing solution suggestions. It is expected that the study with this different perspective will be an example of the sector and related fields as an alternative method. The aim of this study is to examine quality control practices in the garment industry, contribute to statistical control methods and problem-solving procedures, produce suggestions for problem-solving approaches, and disseminate improvement studies.
