BİR DEĞER AKIŞI HARİTALAMA UYGULAMASI: BİR TEKSTİL ENDÜSTRİSİ ÖRNEĞİ
Yalın üretim, 1950’li yıllardan beri kullanılan üretim stratejisidir. Bu
stratejinin ana amacı israfın kaynağını bulmak ve elimine etmeye çalışmaktır.
Şirketler sadece israfı azaltmak değil aynı zamanda rakiplerine karşı rekabet
içinde olmaya çalışırlar. Yalın üretimin verimliliği artırmak için üretim
sistemleri üzerinde kullandıkları bazı araçlar vardır, bunlar; Değer Akışı
Haritalaması, Kanban, Kazien 5s, Conwip, vb. Bu çalışmanın amacı bir tekstil
firmasında değer akışı haritalamasını kullanarak üretim hattını geliştirmektir.
Değer akışı haritalaması üretim sürecini sergilemek ve analiz etmek için en
fazla kullanılan yalın üretim tekniklerinden biridir ve bu şirketlere bütün
üretim hattını kâğıt üzerinde görme imkânı sağlar. Değer akışı haritalaması
bütün üretim sistemini parça parça değil bir resim olarak görmek için
kullanılır. Bu çalışmada değer akışı haritalaması ile mevcut üretim hattı
sergilendi ve yalın üretim teknikleri uygulandı. Bu çalışma İstanbul’dan
Avrupa’ya tekstil ihraç eden bir firmada gerçekleştirildi. Üretimdeki hazırlık
süresini azaltmak ve verimliliği artırmak için 5s ilkeleri uygulandı. Yeni hazırlanan
değer akışı haritasında yalın teknikler uygulanmasıyla birlikte toplam hazırlık
süresi 14.5 günden 5.2 güne düşürülmüştür.
A VALUE STREAM MAPPING IMPLEMENTATION: A CASE of TEXTILE INDUSTRY
Lean manufacturing is
a production strategy that has been used since 1950's. The main concern of this
strategy is to determine resource of waste and try to eliminate waste.
Companies do not only eliminate waste but also they try to keep their competitiveness
as high as their competitors. Lean manufacturing has some tools such as Value
Stream Mapping, Kanban, Kaizen, 5s, CONWIP etc. to imply over the production
system to enhance its effectiveness. The goal of this paper is to apply Value
Stream Mapping to improve production line of a textile company as a case
study. Value stream mapping (VSM) is one
of the most used lean manufacturing technique for illustrating and analyzing
the logic of a production process and it provides companies to see all production
line on the paper. The main idea of VSM is to see the whole system as a picture
not only part by part. In this paper, VSM was used to demonstrate the present
production line and imply lean techniques on this map. Our selected company is
a textile producer which exports their products from Istanbul to Europe. We
apply 5s principles to reduce lead time and increase productivity. VSM final
result shows that Production Lead Time (PLT) decreased 14.5 days to 5.2 days by
applying lean techniques.
