With
ever rising number of shipyards and production capabilities, ship building in
Turkey is a strategic industry that generates significant economic revenue.
However, periodic recessions, one of the characteristics of the ship building
industry, have had lingering effects since the 2008 crisis and caused business
volumes to shrink and consequently inefficient use of resources. Therefore a
data envelopment analysis was carried out covering the years 2005-2016 of
Turkish ship building industry. The model of the study evaluates the efficiency
of number of employees and project capacity on the two most important functions
of a shipyard, the production and repair-maintenance services. Findings reveal
that while the production function resources haven’t been efficiently utilized
after the crisis, repair-maintenance function has been efficiently utilized.
The decrease of new building orders resulted in a downward usage of production
resources, focus have shifted to repair-maintenance and these activities have
been carried out with high levels of efficiency.

VERİ ZARFLAMA ANALİZİ YÖNTEMİYLE TÜRK GEMİ İNŞA SANAYİNİN ETKİNLİK DEĞERLENDİRMESİ

Öz

Türkiye’de
gemi inşa sanayi, devamlı artış gösteren tersane sayıları ve üretim imkânlarıyla
kayda değer ekonomik katkılar elde edilen stratejik bir sanayidir. Ancak gemi
inşa sanayinin bir karakteristik özelliği olan dönemsel durgunluklar 2008
küresel ekonomik krizinden bu yana kendini göstermekte ve sanayinin iş hacmini
küçülterek kaynakların verimsiz kullanılmasına sebep olmaktadır. Bu bağlamda,
Türk gemi inşa sanayinin 2005-2016 yıllarını kapsayan döneme ait etkinliğinin
değerlendirilmesi veri zarflama analizi aracılığıyla gerçekleştirilmiştir.
Araştırmanın modeli, tersanelerin en önemli iki fonksiyonu olan üretim ve
bakım-onarım çıktıları üzerinde, çalışan sayısının ve proje kapasitelerinin
etkinliğini değerlendirmiştir. Elde edilen bulgular, kriz sonrası dönemde
üretim fonksiyonunda kaynakların etkin kullanılamadığına işaret ederken,
bakım-onarım fonksiyonunda tersi bir etkinlik seyri sergilendiğini göstermiştir.
Siparişlerin düşmesinden kaynaklanan üretim azalmasıyla bakım-onarım
faaliyetleri yoğunluk kazanmış ve bu faaliyetler yüksek etkinlik seviyelerinde
gerçekleştirilmiştir.
