Yoğun rekabetin olduğu günümüz
koşullarında artan ve sürekli değişen müşteri talepleri karşısında işletmeler,
üretim sistemlerinin müşteri odaklı, yüksek kaliteli ve aynı zamanda düşük
maliyetli olmasını sağlamalıdır. Özellikler küresel faaliyet gösteren şirketler,
envanter azaltmaya, süreç verimliliğini artırmaya ve israfı ortadan kaldırmaya
yönelik yalın üretim sistemleri ile hedeflerine ulaşmaya çalışmaktadır. Yalın
üretim sistemlerinin işletmelerde nasıl başarılı bir şekilde uygulanabileceğine
dair bir tespit ortaya koymak amacıyla bu çalışmada, bu sistemlerin
uygulanmasının önündeki temel engeller incelemiştir. Bu amaç doğrultusunda
belirsiz ve karmaşık kararları kesin sayısal değerler ile betimleyebilen,
kriterler arasındaki ilişkileri ve önem düzeylerini tespit edebilen için gri
sistem teorisi ile DEMATEL yaklaşımı bütünleşik olarak ele alınmıştır. Bulgular
ile yalın üretim uygulamalarında karşılaşılan engeller arasındaki karşılıklı
ilişkileri ortaya koyularak ve en önemli engeller belirlenmiştir. Makale
sonuçlarının işletmelere ve yöneticilere, yalın üretim uygulamalarında
karşılaşılabilecek engellerin belirlenmesinde uygulanabilecek bir model
önerisiyle yardımcı olacağı düşünülmektedir.

ANALYZING BARRIERS ENCOUNTERED IN LEAN MANUFACTURING APPLICATIONS BY THE GREY DEMATEL INTEGRATED APPROACH

Öz

In
today's highly competitive market conditions, enterprises must ensure that
their production systems are customer focused, high quality and at the same
time low cost. The global companies are trying to achieve their goals with lean
manufacturing systems aimed at reducing inventory, increasing process
efficiency and eliminating wastage. In this study, we have examined the key
barriers to the implementation of lean manufacturing systems in order to
identify how they can be successfully implemented in enterprises. For this
purpose, the grey system theory and the DEMATEL approach are integrated in
order to determine the relations and importance levels between the criterions,
which can represent uncertain and complex decisions with definite numerical
values. The most important obstacles have been identified by demonstrating the
mutual relations between the findings and the obstacles encountered in lean
production practices. It is believed that the results of the article will help
the enterprises and managers to propose a model that can be applied in the
determination of the obstacles that can be encountered in lean production applications.
