Abstract

Malzeme
taşıma ve depolama işlemleri, fabrika içi lojistik hareketlerini kapsayan ve
üretimin her alanında etkin olarak kullanılan faaliyetlerdendir. Temel amacı,
istenen malzemenin, doğru miktarda, doğru yerde, doğru zamanda, doğru
koşullarda, minimum maliyetle ve güvenli bir şekilde taşınmasını sağlamaktır. Yapılan
çalışmada, savunma sanayinde yer alan bir firmanın üretim bölümündeki taşıma
problemlerine çözüm getirmek ve uygun taşıma yönteminin seçimini sağlamak
amaçlanmıştır. Bu kapsamda, imalat bölümünde taşımada meydana gelen problemler
ve bu problemlerin nedenlerini belirlemek için Pareto analizi yapılmıştır.
Üretimi aksatan bu problemleri ortadan kaldırmak amacıyla öncelikle imalat
ortamına özgü olarak taşımada önem arz eden kriterler (araç kapasitesi, satın
alma maliyeti, taşıma hassasiyeti, araç hızı, üretim ortamına uygulanabilirlik,
taşıma kolaylığı, bakım-onarım sıklığı, ergonomi olmak üzere sekiz farklı
kriter) belirlenmiş ve kriterlerin önem dereceleri AHP yöntemi ile
hesaplanmıştır. Sonrasında ise yine imalat ortamına uygun dört farklı taşıma
alternatifi (el arabası, römorklu çekici tren, çatallı yük arabası ve otomatik
yönlendirmeli araçlar) belirlenerek; bu alternatifler içerisinden en uygun
olanın seçimi VIKOR ve MOORA yöntemleri kullanılarak yapılmıştır.

SELECTION OF MATERIAL HANDLING SYSTEM by USING VIKOR&MOORA METHODS

Abstract

Material handling and storage operations are activities
that are used effectively in all areas of production including internal
logistics movements. The main objective is to ensure that the needed material
is transported in the right amount, in the right place, at the right time, in
the right conditions, with minimum cost and safely. In this study, it is aimed
to solve the material handling problems in the production department of a
company in the defense industry and to ensure the selection of suitable
material handling methods. In this context, Pareto analysis has been carried
out in order to determine the material handling problems and the causes of
these in the production. In order to eliminate these problems that interrupt
the production, firstly, the criteria (eight different criteria for material
handling: vehicle capacity, purchase cost, transportation accuracy, vehicle
speed, applicability to production environment, ease of transportation,
maintenance-repair frequency, ergonomics), which are important in the material
handling and dependent to production environment, have been determined. And the
importance degree of criteria are computed by AHP. Then, four different
alternatives (wheelbarrow, trailer towing trailers, forklift trucks,
auto-guided vehicles) suitable for production system are determined to select
the most appropriate one among these alternatives by comparing VIKOR and MOORA
methods.
