YALIN ÜRETİM UYGULAMALARINDA KARŞILAŞILAN ENGELLERİN GRİ DEMATEL BÜTÜNLEŞİK YAKLAŞIMIYLA ANALİZİ

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

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.
