Bilişim Sektöründeki Şirketlerin Etkinliklerinin Veri Zarflama Analizi ile Değerlendirilmesi(Evaluation Of The Efficiency Values Of The Companies In Information Technology Sector With Data Envelopment Analysis)

Etkinlik degeri isletmelerin basari duzeylerinin olculmesinde kullanilan onemli araclardan biridir. Ancak etkinlik degerinin olculmesi sirasinda cok sayida girdi ve ciktinin birlikte dusunulmesi gereklidir. Bircok girdi ve ciktinin birlikte incelenmesine imkan saglayan tekniklerden biri veri zarflama analizidir. Bu calismada sirasiyla, Veri Zarflama Analizi (VZA) hakkinda bilgi verilmis, yontemin matematiksel isleyisi aciklanmis, konu ile ilgili yapilmis calismalara deginilmis ve BIST Bilisim endeksinde yer alan oniki firmanin etkinlik degerleri veri zarflama analizi (VZA) ile belirlenerek sonuclar degerlendirilmistir. Buna gore bazi firmalarin cok dusuk yatirimla oldukca tatminkar kazanc elde ettigi bazi firmalarin ise tam tersine yuksek yatirima ragmen oransal olarak karinin dusuk oldugu gorulmustur.

Data Envelopment Analysis (DEA) is one of the techniques that provides to evaluate many different input and output factors together. In this study, the information has been given about Data Envelopment Analysis, the mathematical process has been explained,the literature review has been made and the efficiency values of the twelve companies in BIST Information Index have been determined with data envelopment analysis and the results have been evaluated respectively. The results show that some companies have got satisfactory profit levels with low investment and some companies have got low profit in spite of huge investment.
