Gelişmiş teknolojiye sahip savunma sistemlerinin tedarik edilmesi ve yaşam döngüsü içerisinde
sürdürülebilirliği lojistik süreçler açısından her geçen gün daha maliyetli ve karmaşık olabilmektedir.
Performansa Dayalı Lojistik (PDL), tedarik zinciri ve lojistik vasıtasıyla sistemlerin desteklenmesi ve
tedarik edilmesi için ortaya konulan yeni yaklaşımlardan birisidir. Bu yaklaşım, son kullanıcı ihtiyacının
operasyonel hazır bulunuşluk açısından belirli performans hedefleri dikkate alınarak ve daha uygun
maliyetle karşılanmasına önem vermektedir. Performans değerlendirilmesi için kullanılan parametrik ve
parametrik olmayan birçok araç ve yöntem kullanılmaktadır. Parametrik olmayan yöntemler arasında en
çok tercih edilen analiz yöntemi ise Veri Zarflama Analizi (VZA)’dır. VZA, karar verme birimlerinin
performans ve göreceli etkinliklerini değerlendirmek için kullanılan doğrusal programlama tabanlı bir
yöntemdir. Bu çalışmada, gerçek bir örnek olay çalışması ele alınmıştır. PDL stratejisi kapsamında yerli
akü üreticisi firmaların geçmiş yıllara ait verileri dikkate alınarak dinamik bir performans değerlendirmesi
yapılmıştır. Performans değerlendirmesi için VZA ile Malmquist Toplam Faktör Verimliliği Endeksinden
yararlanılmıştır. Çalışmada, yerli 12 adet akü üretici firmanın geçmiş dört yıllık verileri dikkate alınmış
ve iki adet girdi ile iki adet çıktı faktörü kullanarak etkinlikleri analiz edilmiştir. Analiz sonucunda
yalnızca bir akü üreticisi firmanın tüm dönemlerde etkin olduğu sonucuna ulaşılmıştır.

A Dynamic Performance Evaluation For Performance Based Logistics: An Applicaton For Defense Industry

Öz

Supplying advanced technology defense systems and sustainability within the life cycle can be
more costly and complex in terms of logistical processes day by day. Performance Based Logistics (PBL)
is one of the new approaches to support and supply systems through supply chain and logistics. This
approach focuses on importance to satisfying the needs of the end-user in terms of operational availability
by taking into account the specific performance targets and with cost effectively. Many parametric and
nonparametric methods are used for performance evaluation. The most preferred method of analysis
among nonparametric methods is Data Envelopment Analysis (DEA). DEA is a linear programmingbased method used to evaluate the performance and relative effectiveness of decision-making units. A
real case study is carried out and the results are discussed.In the context of PDL strategy, a dynamic
performance evaluation is performed by taking into consideration the data of the domestic battery
manufacturer companies in the past years. For this purpose, DEA and the Malmquist Total Factor
Productivity Index are used. In the study, 12 domestic battery manufacturers are taken into consideration and their efficiencies are analyzed. The results from this analysis indicate that only one battery
manufacturer is effective in all periods
