Bu çalışma, ülkelerin telekomünikasyon yatırımlarının miktarlarını araştırmakta ve verileri matematiksel olarak modellemek için uygun bir yöntem aramaktadır. Çalışmada kesirli kalkülüs kullanılarak model 1 ve model 2 olarak adlandırılan iki yöntem önerilmiştir. Fransa, Almanya, İtalya, İspanya, Türkiye ve OECD toplamından elde edilen telekomünikasyon yatırımlarının yıllık verileri kullanılarak geleneksel polinom modeli ile 1 ve 2 modelleri arasında bir karşılaştırma yapılmıştır. Önerilen yöntemler, geleneksel polinom modelinden daha iyi performans gösterdiği gözlenmiştir.

This study investigates the amounts of countries’ telecommunication investments and seeks a decent method to mathematically model the data. Using fractional calculus, two methods are proposed which are called model 1 and model 2 in the study. A comparison is performed between the conventional polynomial model and models 1 and 2 using the yearly data of telecommunication investments from France, Germany, Italy, Spain, Turkey, and the OECD total. The proposed methods outperform the conventional polynomial model.
