Abstract

Through the developing possibilities and advancing technology, companies have focused their eyes on the Supply Chain (SC) instead of focusing on the time in production to increase their profitability rates, and visible competition has started among the companies in this field. The supply process, the beginning part of SC, offers an effective improvement area. The most critical player in this process is the suppliers.
Finding the right supplier who can provide the right quality, time, and amount of products or services to the company constitutes the primary purpose of supplier selection, which can make SC more efficient and effective. On the other hand, supplier selection is a complex problem as it is typically a multi-criteria decision-making (MCDM) problem involving various conflicting criteria where the decision maker’s knowledge is often unclear and uncertain.
This variable has been weighted with the Analytical Hierarchy Process (AHP), one of the MCDM methods, by determining the evaluation criterion of a company’s supplier operating in the thermotechnical sector, and the final supplier selection of these dimensions has been decided by using TOPSIS. The primary purpose of the study; For the company, it is to rate the choice of a particular material source supplier and reduce the commercial and strategic decisions for the purchaser’s material group.

AHP VE TOPSIS ENTEGRASYONU İLE TERMOTEKNİK SEKTÖRÜNDE FAALİYET GÖSTEREN BİR FİRMADA TEDARİKÇİ SEÇİMİ

Abstract

Gelişen olanak ve ilerleyen teknoloji sayesinde, firmalar karlılık oranlarını arttırmak amacıyla üretimdeki zamanlara odaklanmak yerine gözlerini Tedarik Zinciri (TZ) üzerine dikmişlerdir ve firmalar arasında bu alanda gözle görülür bir rekabet başlamıştır. TZ’nin başlangıç kısmı olan tedarik süreci etkin bir iyileştirme alanı sunmaktadır. Bu sürecin en önemli oyuncusu ise tedarikçilerdir.
Firmaya doğru kalitede, doğru zamanda ve doğru miktarda ürün veya hizmet sunabilecek doğru tedarikçiyi bulma süreci TZ’yi daha verimli ve daha etkin duruma getirebilecek olan tedarikçi seçiminin temel amacını oluşturmaktadır. Öte yandan, tedarikçi seçimi tipik olarak karar vericinin bilgisinin genellikle belirsiz ve kesin olmadığı çeşitli çelişkili kriterleri içeren çok kriterli karar verme (ÇKKV) problemi olması nedeniyle zor bir problemdir.
Yapılan bu çalışmada termoteknik sektöründe faaliyet gösteren bir firmanın tedarikçi değerlendirme kriterleri belirlenerek, ÇKKV yöntemlerinden Analitik Hiyerarşi Prosesi (AHP) ile ağırlıklandırılmış ve bu kriterler doğrultusunda tedarikçi seçimine TOPSIS kullanılarak karar verilmiştir. Çalışmanın ana amacı; firmanın için, belirli bir materyal grubunda tedarikçi seçimini derecelendirmek ve satın alma sorumlusunun materyal grubu için alacağı ticari ve stratejik kararları kolaylaştırmaktır.
