Abstract

Rekabetin yoğun yaşandığı günümüz iş dünyasında işletmeler, maliyetlerini sorgulamaya devam etmektedir. Bu bağlamda, lojistik maliyetlerine önemli etkisi olan depo yeri seçimi kritik bir önem arz etmektedir. Bu çalışmada bahsedilen depo yeri seçim modeli, ürünlerin dağıtım ağı verimliliğine katkı vermek ve lojistik maliyetlerini minimize etmek amacıyla geliştirilmiştir. Çalışmada, depo seçim probleminin çözümüne yönelik 3 farklı yöntemin sentezlenmesi yapılmış olup, bunlardan birincisi, Analitik Hiyerarşi Prosesi (AHP); ikincisi, Vise Kriterijumska Optimizacija I Kompromisno Resenje (VIKOR); üçüncüsü ise Multi-Objective Optimization by Ratio Analysis (MOORA) yöntemidir. Kriterlerin ağırlıklandırılmasında AHP yöntemi, alternatiflerin sıralanmasında ise VIKOR ve MOORA yöntemleri kullanılmıştır. AHP ve VIKOR yöntemlerinde klasik ölçekler yerine gerçek verilerin ve MOORA yönteminin bu problemde kullanılması, yeni bir bakış açısı ve çözüm önerisi olması açısından önemli görülmektedir. Uygulama, büyük ölçekli bir döküm fabrikasının 3 ayrı ilde depo yeri belirlenmesi problemi üzerine, 11 alternatifin değerlendirilmesiyle gerçekleştirilmiştir. Çalışmada, 2 ayrı modelden elde edilen sonuçlar karşılaştırılmış ve uygulama sonuçlarına göre belirlenen 3 alternatif ilde ürün deposu kurulması kararı alınmıştır.

APPLICATION OF AHP-VIKOR AND MOORA METHODS IN WAREHOUSE SITE SELECTION PROBLEM

Abstract

Today companies continue to examine their costs in business life where competition is hard. In this sense, warehouse site selection, which is significantin terms of logistics costs, becomes a critical process. Warehouse site selection decision making model proposed in this study is developed for contributing the efffiency of distribution network and minimizing logistics costs. In this study, to solve warehouse site selection problem 3 different methods are synthesised, which are Analytical Hierarchy Prıocess (AHP), Vise Kriterijumska Optimizacija I Kompromisno Resenje (VIKOR) and with Multi-Objective Optimization by Ratio Analysis (MOORA). AHP method is used for determining the criteria of alternatives and VIKOR and MOORA methods are used for ranking of alternatives.Using real data instead of classical pairwise comparison scales for AHP and VIKOR applications and the use of MOORA method in warehouse site selection problem have been important for considering a new approach and solution method in this field. The application is carried out for the decision problem of determining 3 best alternatives of a casting factory among 11 alternatives. In the study, comparisons are conducted for results of both of the methods and final decision is made according to application results.
