Factory Location Selection Using AHP, TOPSIS and ELECTRE Methods: A Case Study

Abstract

This study employs MCDM techniques—specifically AHP, TOPSIS, and ELECTRE—to identify the optimal location for a facility based on a set of predefined criteria: Proximity to Raw Materials, Proximity to Market, Workforce Potential, Technical Capabilities, Fixed Costs, and Public Supports. Within the methodological framework, the AHP approach was utilized to accurately assign weights to the evaluation criteria, whereas TOPSIS was applied to rank the alternatives based on their proximity to the ideal solution, and ELECTRE was employed to analyze the dominance relationships among the options. The implementation phase involved a comprehensive analysis of factors such as raw material access, cost structures, and labor availability using these methods, revealing that all three approaches yielded consistent and corroborative results. The case study concluded that Izmir, which received the highest performance score according to all three MCDM methods based on the defined criteria, stands out as the most strategically suitable city for olive oil factory locations.

AHP, ELECTRE, TOPSIS Yöntemleri ile Fabrika Lokasyon Seçimi: Vaka Çalışması

Öz

Bu çalışma, önceden tanımlanmış bir dizi kritere (Hammaddeye Yakınlık, Pazara Yakınlık, İşgücü Potansiyeli, Teknik Kapasite, Sabit Maliyetler ve Kamu Destekleri) dayanarak bir tesis için en uygun yeri belirlemek amacıyla çok kriterli karar verme (MCDM) tekniklerini (özellikle AHP, TOPSIS ve ELECTRE) kullanmaktadır. Metodolojik çerçeve içinde, değerlendirme kriterlerine doğru ağırlıklar atamak için AHP yaklaşımı kullanılırken, alternatifleri ideal çözüme yakınlıklarına göre sıralamak için TOPSIS ve seçenekler arasındaki baskınlık ilişkilerini analiz etmek için ELECTRE kullanılmıştır. Uygulama aşaması, bu yöntemler kullanılarak hammadde erişimi, maliyet yapıları ve işgücü mevcudiyeti gibi faktörlerin kapsamlı bir analizini içermiş ve üç yaklaşımın da tutarlı ve birbirini doğrulayan sonuçlar verdiğini ortaya koymuştur. Vaka çalışması, tanımlanmış kriterlere göre üç MCDM yönteminin tümüne göre en yüksek performans puanını alan İzmir'in, zeytinyağı fabrikası yerleri için stratejik olarak en uygun şehir olduğu sonucuna varmıştır.
