Sağkalım ve Güvenilirlik Analizlerinde Yeni Bir Olasılık Dağılımı

Öz

Sağkalım ve güvenilirlik analizleri; bir makinenin, malzemenin ya da bir canlının “ömrünü sürdürme ihtimali” ve “bu ömrün sonlanmasına kadar geçen süre” ile ilgilenilir. Bu analizlerde, verinin en iyi şekilde temsil edilebilmesi için veriyi modelleyecek olasılık dağılımının brlirlenmesi çok önemlidir. Bu çalışmada, bu alanda kullanılabilecek yeni bir olasılık dağılımı tanımlanmış ve bu dağılıma ilişkin istatistiksel özellikler elde edilmiştir. Uygulama iki farklı, gerçek güvenilirlik veri seti üzerinde gerçekleştirilmiş ve bu verileri modellemede daha önce kullanılmış olasılık dağılımları ile karşılaştırılmıştır. Önerilen dağılımın veriyi diğer dağılımlardan çok daha iyi modellediği gösterilmiştir.
