APPLICATION OF ANALYTIC HIERARCHY PROCESS AND GOAL PROGRAMMING IN SUPPLIER SELECTION PROBLEM

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
