Bir perakende firmasında çoklu karar verme yöntemleri entegre yaklaşımı ile tedarikçi performans değerlendirmesi

Today, in a very rapid development, the competitive structure of the retail world is increasing every passing day. Companies are adopting different strategies to maintain the race ahead. Most of these strategies are shaped around the product features. The product cost, sales price, quality and customer attention are considered as the important factors. The supplier selection process has become critic, because these important elements are based on supplier characteristics.Because supplier selection has become such an important issue, the number of studies on this subject in academic literature has started to rise. The analysis which contains various models and techniques was used in these studies to make the companies have an ability to choose optimum suppliers.In this study we address the measurement of supplier efficiencies in a retail company. For that purpose, we suggest a two stage approach which employs both the Data Envelopment Analysis (DEA) and the Analytical Hierarchical Process (AHP) methods. In the first stage, we measure the efficiency of the suppliers with DEA method. Next, in the second stage, we use the AHP method to verify the results obtained with the first stage. As an illustrative example, we have applied the proposed approach in the supplier selection process of a retail company. We have observed that the results obtained by both DEA and AHP methods are consistent.
