Reducing Vacuum Charge Test Time Using Exploratory Data Analysis

Tuğba Demircan Kutluay, Süleyman Eken

Nowadays, external factors such as increasing levels of competition and having a permanent place in the market are directing companies to use their systems more efficiently, to reduce their costs, and to produce higher quality products. Process improvement steps are important in studies of these companies. In this study, the vacuum test station that created a bottleneck was determined by analyzing the production process in an exploratory way. Through exploratory data analysis, it was possible to perform an initial data investigation to discover patterns, spot anomalies, test hypothesis, and check assumptions with the help of summary statistics and graphic representations. By determining the value-added test time of the vacuum test station, the process time was reduced. Using the new test period, production capacity increased and a more efficient operation of the line was achieved. The number of daily production increased from 136 to 188, line efficiency increased from 55% to 77%, and the stations waiting for each other decreased from 35% to 10%. At the same time, the annual production capacity of the line increased by 27%, reaching from 58K to 79K.

Keşifsel Veri Analizi Kullanarak Vakum Şarj Test Süresinin Azaltılması

Tuğba Demircan Kutluay, Süleyman Eken

Günümüzde giderek artan rekabet koşulları ve pazarda kalıcı olabilme gibi dış faktörler firmaların sistemlerini daha verimli kullanmaya, maliyetlerini azaltmaya, yüksek kalite düzeyinde ürün üretmeye yönlendirmektedir. Firmaların yaptıkları bu çalışmalarda proses iyileştirme adımları önem taşımaktadır. Bu çalışmada üretim süreçleri keşifsel yolla analiz edilerek darboğaz oluşturan istasyon tespit edilmiştir. Keşifsel veri analizi ile kalıpları keşfetmek, anormallikleri tespit etmek, özet istatistikler ve grafik gösterimler yardımıyla varsayımları kontrol etmek için veriler üzerinde ilk araştırmaları gerçekleştirmek mümkün olmuştur. Vakum test istasyonunun katma değersiz test süresi belirlenerek proses süresi azaltılmıştır. Belirlenen yeni test süresi ile üretim kapasite artışı ve hattın daha verimli çalışması sağlanmıştır. Bu sayede günlük üretim adedi 136’dan 188’e, hat verimliliği %55’ten %77’ye artmış ve istasyonların birbirini beklemesi %35’ten %10’a düşmüştür. Aynı zamanda hattın yıllık üretim kapasitesi %27 artarak 58K dan 79K adede ulaşmıştır.
