A Multi Criteria Decision Making Methodology Based Novel Model For Supplier Selection

Abstract

Supplier selection and measurement of supplier performance are multiple criteria decision making (MCDM) problems and have strategic importance for all industries. The study contains analyzed factors that are affecting the process of the supply chain with respect to supplier performance. Supplier performance measures is a tool to determine whether suppliers are doing their job as expected. The importance of supplier performance measurement should not be underestimated due to direct and indirect productivity-related consequences. Supplier evaluation is a complex multiple criteria decision-making problem that is affected by several conflicting factors. Because of this, the measurement of supplier performance has been becoming increasingly important and critical throughout the world. The purpose of this paper is to investigate the MCDM methods and propose a novel method in order to check how the performance of suppliers is being measured with using three different methods. Qualification and final selection of the supplier can be done with a proposed novel model. In the study, the criteria are weighted with the Analytical Hierarchy Process, while TOPSIS and VIKOR methods are used to evaluate and rank the suppliers. Evaluating supplier performance, derive the importance of the main criteria and sub-criteria applied in decision-matrix to sort the suppliers according to the measurement of supplier performance criteria.

Tedarikçi Seçiminde Çok Kriterli Karar Verme Tabanlı Yeni Bir Model

Abstract

Tedarikçi seçimi ve performansının ölçülmesi tüm endüstriler için stratejik öneme sahip çok kriterli karar verme (ÇKKV) problemleridir. Çalışma, tedarik zinciri sürecini etkileyen, analiz edilmiş faktörlerin tedarikçi performansına dayalı şekilde ölçümlenmesini içermektedir. Tedarikçi performans ölçütleri, tedarikçilerin işlerini beklendiği ve istenilen formatta yapıp yapmadıklarını belirleyen bir araçtır. Tedarikçi performans ölçümü verimlilikle alakalı doğrudan ve dolaylı sonuçları sebebiyle hafife alınmamalıdır. Tedarikçi değerlendirmesi, çeşitli ve karmaşık faktörlerden etkilenen yapıda, çok kriterli bir karar verme problemidir. Bu nedenle, tedarikçi performansının ölçülmesi giderek daha önemli ve kritik hale gelmektedir. Bu çalışmanın amacı, tedarikçilerin performansının ölçümlenmesini ÇKKV yöntemleriyle incelemek ve üç yöntemi barındıran yeni bir metodolojisi önermektir. Çalışmada Analitik Hiyerarşi Süreci yöntemi ile kriterlerin ağırlandırılması yapılırken TOPSIS ve VIKOR yöntemleri ile tedarikçilerin değerlendirilmesi ve sıralanması sağlanmaktadır. Tedarikçi yeterliliğinin testi ve nihai seçimi önerilen yeni modelle yapılabilir. Tedarikçi performansının değerlendirilmesi, tedarikçi performansı için belirlenen ana ve alt kriterlere göre ölçümlenmekte ve karar matrisi ile alternatiflerin sıralanmasını sağlamaktadır.
