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.

Mathematical Modeling of European Countries’ Telecommunication Investments

Öz

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.
