In addition to physiological needs such as hunger and thirst, people also have shelter needs. As a result of natural disasters such as fire, flood, earthquake, epidemics and wars, people settle in different regions. The world's increasing population, epidemics and disasters show how priority and vital the construction industry is. The earthquake disaster in Turkey and the increasing migration due to wars in the border regions once again reveal how important and priority the construction sector is for Turkey. As in many other sectors, labor and financial resources must be used efficiently in the construction industry. Measuring the efficiency of construction companies operating in Turkey is very important for the current situation of the construction industry. This study aims to evaluate the efficiency of ten companies on the Fortune 500 list operating in the field of construction and contracting in Turkey. The Data Envelopment Analysis (DEA) method is generally widely used in efficiency measurement. In the study, input-oriented CCR model and Super Efficiency (SE)-CCR model were used for efficiency analysis. For DEA analysis, "total assets" and "number of employees" were used as input variables, and "net sales" were used as output variables. According to the DEA analysis results, three of the ten companies considered as decision-making units (DMU) were efficient. Efficient companies are ranked among themselves according to the results of the SE CCR model.

VERİ ZARFLAMA ANALİZİ YÖNTEMİ KULLANILARAK İNŞAAT SEKTÖRÜNDE ETKİNLİK ÖLÇÜMÜ

Öz

İnsanların açlık susuzluk gibi fizyolojik ihtiyaçlarına ek olarak barınma ihtiyaçları da bulunmaktadır. Yangın, sel, deprem gibi doğal afetler, salgınlar ve savaşlar neticesinde insanlar farklı bölgelere yerleşmektedirler. Dünya genelinde artan nüfus, salgın hastalıklar ve felaketler inşaat sektörünün ne kadar öncelikli ve hayati öneme sahip bir sektör olduğunu göstermektedir. Türkiye’de yaşanan deprem felaketi ve sınır komşularında yaşanan savaşlara bağlı olarak artan göç inşaat sektörünün Türkiye açısından ne kadar önemli ve öncelikli olduğunu bir kez daha gözler önüne sermektedir. Diğer birçok sektörde olduğu gibi inşaat sektöründe de işgücü ve finansal kaynakların etkin bir şekilde kullanılması gerekmektedir. Türkiye’de faaliyet gösteren inşaat firmalarının etkinliklerinin ölçülmesi inşaat sektörünün mevcut durumu açısından oldukça önemlidir. Bu çalışmanın amacı Fortune 500 listesinde bulunan ve Türkiye’de inşaat ve taahhüt alanında faaliyet gösteren on firmanın etkinlik değerlendirmesini gerçekleştirmektir. Etkinlik ölçümünde genellikle Veri Zarflama Analizi (VZA) yöntemi yaygın bir şekilde kullanılmaktadır. Çalışmada etkinlik analizleri için girdi odaklı CCR modeli ve Süper Etkinlik (SE)-CCR modeli kullanılmıştır. VZA analizi için "toplam aktifler" ve "çalışan sayısı" girdi değişkenleri, "net satış" ise çıktı değişkeni olarak kullanılmıştır. VZA analizi sonuçlarına göre karar verme birimi (KVB) olarak ele alınan on firma arasından üçünün etkin olduğu tespit edilmiştir. Etkin çıkan firmalar SE CCR modeli sonuçlarına göre kendi aralarında sıralanmıştır.
