Abstract

This study aims to reduce the delivery time by applying value stream mapping techniques in the commercial mirror product group of a company operating in Bursa, producing automotive parts. For this purpose, the product family was first selected by ABC analysis, a time study was conducted to determine station cycle times, and stocks were counted. The current situation map was drawn, and the points where stocks and transportations were intense were determined. NVA/VA analyses were performed to differentiate the value-added and non-value-added process steps, and a spaghetti diagram was drawn to determine the walks in the assembly line. The future situation map was drawn by considering the kaizen suggestions developed as a result of the analyses made. With this study, the company’s delivery time was shortened by 52%. In addition, an ideal situation map has been drawn for an ideal scenario where the system has unlimited possibilities, and it has been shown that the delivery time can be shortened by 93% in such a case.

Özet

Bu çalışma, Bursa’da faaliyet gösteren otomotiv parçaları üreten bir firmanın ticari ayna ürün grubunda değer akış haritalama tekniği uygulayarak teslim süresini azaltmayı amaçlamaktadır. Bu doğrultuda, öncelikle ABC analizi ile ürün ailesi seçilmiş, istasyon çevrim sürelerini belirlemek amacıyla zaman etüdü yapılmış ve stoklar sayılmıştır. Mevcut durum haritası çizilerek stok ve taşımaların yoğun olduğu noktalar belirlenmiştir. Değer katan ve katmayan işlem adımlarının ayrıştırılması için NVA/VA analizleri yapılmış ve montaj hattı içerisindeki yürümeleri belirlemek için spagetti diyagramı çizilmiştir. Yapılan analizler sonucunda geliştirilen kaizen önerileri dikkate alınarak gelecek durum haritası çizilmiştir. Bu çalışma ile firmanın teslim süresi %52 kısalmıştır. Ayrıca, sistemin sınırsız imkânlara sahip olduğu ideal bir senaryo için ideal durum haritası çizilmiş, böyle bir durumda teslim süresinin %93 kısaltılabileceği gösterilmiştir.
