Abstract

In this paper, a goal programming (GP) approach was utilized to solve the problem of
materials’ supplier selection for a company operating in textile industry. The proposed
approach determines the company’s objectives and assigns their relative importance to be
used for Analytic Hierarchy Process (AHP). Weighted GP approach was used to develop two
alternative mathematical models for selecting the suppliers. One of the alternatives restricts
the number of suppliers to be selected to two for each material; the other one does not put any
restrictions on this subject. The results are compared within each other and with the current
system in terms of the objectives determined at the beginning.

TEDARİKÇİ SEÇİMİ PROBLEMİNDE HEDEF PROGRAMLAMA VE ANALİTİK HİYERARŞİ PROSESİNİN UYGULAMASI

Abstract

Bu çalışmada bir tekstil firmasının tedarikçi seçimi problemini çözmek üzere bir hedef
programlama yaklaşımı geliştirilmiştir. Geliştirilen yöntem firmanın amaçlarını ve önem
derecelerini belirler. Bu veriler Analitik hiyerarşi süreci ile ağırlıklara dönüştürülür.
Yöntemin ikinci aşamasında hesaplanan değerler ile ağırlıklı hedef programlama modeli
çalıştırılır. Model iki alternatif sonuç oluşturur. Birincisinde her malzeme için tedarikçi sayısı
iki ile sınırlandırılmıştır. İkincisinde ise tedarikçi sayısı üzerinde herhangi bir kısıt yoktur.
Her iki alternatifin sonuçları birbiriyle ve firmanın mevcut durumuyla belirlenen amaçlar
doğrultusunda karşılaştırılmıştır
