Rekabetin her geçen gün daha yoğun yaşandığı günümüz kapitalizminde, performans ile onun unsurları olan etkinlik ve verimlilik artan önemini korumaktadır. Üretim sisteminde yüksek bir performans gerçekleştirmek için tüm süreçte optimal kaynak kullanımının sağlanması, maliyetlerin düşürülmesi gerekmektedir. Malzeme arzı, malzeme tedariki ve lojistik süreci boyunca tüm aşama optimum uyum içinde gerçekleştirilmelidir. Dolayısıyla performans artışında, lojistik sektörlerinin etkinliğinin ve verimliliğinin sağlanması önem kazanmaktadır. Bu çalışmada, Avrupa Geçiş Ekonomisi Ülkeleri içinde geçişi tamamlamış olan 11 ülkenin etkinlik ve verimlilik analizi, Lojistik Performans Endeksi alt boyutlarına ait veriler kullanılarak Girdi Odaklı Ölçeğe Göre Sabit Getiri (CCR) ve Girdi Odaklı Ölçeğe Göre Değişken Getiri (BCC) Modellerine göre yapılmıştır. Lojistik Performans Endeksinin altı alt boyutundan üçü (gümrük, altyapı ve lojistik kalite) girdi olarak kullanılırken, diğer üçü ise (uluslararası gönderiler, izleme-takip ve zamanında teslimat) çıktı olarak ele alınmıştır. Veri Zarflama Analizi ile yapılan çalışmada “EMS Paket Programı” kullanılarak etkinlik değerlendirilmesi yapılmıştır. Analiz bulgularından elde edilen sonuçlara göre etkin ve verimli olan ülkeler bulunmuştur. Aynı zamanda etkinsiz ve verimsiz olan ülkeler de bulunarak, etkin olmayan ülkelerin ideal etkinlik düzeyine çıkabilmesi için girdi değişkenlerin iyileştirme oranları hesaplanmıştır.

Evaluation of European transition economies using the logistics performance index with data envelopment analysis

In today's capitalism, where competition is more intense day by day, performance and its elements, efficiency, and productivity, remain of increasing importance. In order to realise a high performance in the production system, it is necessary to ensure optimal resource utilisation in the whole process and to reduce costs. The entire stage during the material supply, material procurement and logistics process should be carried out in optimal harmony. Therefore, ensuring the activity and efficiency of logistics sectors has come into prominence in performance improvement. In this study, the efficiency and productivity analysis of 11 countries that have completed the transition within the European Transition Economy Countries were made according to the Input-Oriented Constant Return to Scale Model and Input-Oriented Variable Returns to Scale Model by using the data belonging to the Logistics Performance Index sub-dimensions. Three of the six sub-dimensions of the Logistics Performance Index (customs, infrastructure, and logistics quality) were used as inputs, while the other three (international shipments, tracking / tracking, and on-time delivery) were considered as outputs. In the study conducted with Data Envelopment Analysis, the efficiency evaluation was made by using the "EMS Package Program". According to the results acquired from the analysis findings, efficient and productive countries were found. At the same time, ineffective and nonproductive countries were found and the improvement rates of the input variables have been calculated so that the inefficient countries can reach the ideal efficiency level.
