WEIBULL fonksiyonu, \u00f6zellikle istatistiksel analizlerde yararl\u0131 olan ve Weibull da\u011f\u0131l\u0131m\u0131n\u0131 temsil eden bir Excel ve Google E-Tablolar i\u015flevi olup, g\u00fcvenilirlik testleri ile m\u00fchendislik alan\u0131nda yayg\u0131n olarak kullan\u0131l\u0131r. Bu fonksiyon, bir ar\u0131zan\u0131n olma olas\u0131l\u0131\u011f\u0131n\u0131 ya da bir \u00fcr\u00fcn\u00fcn \u00f6mr\u00fc gibi s\u00fcrekli rastgele de\u011fi\u015fkenlerin da\u011f\u0131l\u0131m\u0131n\u0131 modellemede etkilidir.<\/p>\n

Ba\u015flang\u0131\u00e7 olarak WEIBULL i\u015flevinin s\u00f6z dizimi<\/h2>\n

WEIBULL i\u015flevinin genel s\u00f6z dizimi a\u015fa\u011f\u0131daki gibidir:<\/p>\n

=WEIBULL(x, lambda, k, kuyruk)<\/code><\/pre>\n
    \n
  • x<\/code>: Da\u011f\u0131l\u0131m\u0131n hesaplanaca\u011f\u0131 de\u011ferdir.<\/li>\n
  • lambda<\/code>: \u00d6l\u00e7ek parametresi olup, da\u011f\u0131l\u0131m\u0131n geni\u015fli\u011fini belirler.<\/li>\n
  • k<\/code>: \u015eekil parametresi, da\u011f\u0131l\u0131m\u0131n \u015feklini kontrol eder.<\/li>\n
  • kuyruk<\/code>: E\u011fer TRUE ise fonksiyon k\u00fcm\u00fclatif da\u011f\u0131l\u0131m fonksiyonunu (CDF), FALSE ise tamamlay\u0131c\u0131 k\u00fcm\u00fclatif da\u011f\u0131l\u0131m fonksiyonunu (CCDF) hesaplar.<\/li>\n<\/ul>\n
    Pratik Uygulamalar<\/h2>\n
    WEIBULL i\u015flevinin uygulamalar\u0131na dair iki temel \u00f6rnek verece\u011fim.<\/p>\n
    \u00d6rnek 1: G\u00fcvenilirlik Analizi<\/h2>\n
    Bir \u00fcr\u00fcn\u00fcn ortalama olarak ne kadar s\u00fcre \u00e7al\u0131\u015ft\u0131ktan sonra ar\u0131zalanabilece\u011fini tahmin etmek i\u00e7in WEIBULL i\u015flevi kullan\u0131labilir.<\/p>\n
     =WEIBULL(1000, 1500, 3, TRUE) <\/code><\/pre>\n
    Bu form\u00fcl, bir \u00fcr\u00fcn\u00fcn 1000 saat sonunda ar\u0131zalanma olas\u0131l\u0131\u011f\u0131n\u0131 hesaplar. Burada, lambda<\/code> 1500 ve k<\/code> 3’t\u00fcr. Sonu\u00e7, \u00fcr\u00fcn\u00fcn 1000 saatte ar\u0131zalanma olas\u0131l\u0131\u011f\u0131n\u0131 k\u00fcm\u00fclatif olarak verir.<\/p>\n
    \u00d6rnek 2: \u00dcr\u00fcn \u00d6mr\u00fc Tahmini<\/h2>\n
    Belirli bir g\u00fcvenilirlik seviyesine ula\u015fmak i\u00e7in bir \u00fcr\u00fcn\u00fcn tahmini \u00f6mr\u00fcn\u00fc hesaplama. Diyelim ki, \u00fcr\u00fcn\u00fcn\u00fcz\u00fcn %95 g\u00fcvenilirlikle ne kadar s\u00fcre \u00e7al\u0131\u015faca\u011f\u0131n\u0131 \u00f6\u011frenmek istiyorsunuz.<\/p>\n
     =WEIBULL(0.95, 1500, 3, FALSE) <\/code><\/pre>\n
    Bu form\u00fcl, lambda<\/code> de\u011feri 1500 ve k<\/code> de\u011feri 3 olan bir \u00fcr\u00fcn i\u00e7in %95 g\u00fcvenilirlikle \u00e7al\u0131\u015facak s\u00fcreyi tahmin eder. Burada, kumulatif olmayan da\u011f\u0131l\u0131m kullan\u0131ld\u0131\u011f\u0131 i\u00e7in kuyruk<\/code> FALSE olarak ayarlanm\u0131\u015ft\u0131r.<\/p>\n
    Sonu\u00e7 ve Yorumlar<\/h2>\n
    WEIBULL fonksiyonu, verilen parametrelerle \u00fcr\u00fcn \u00f6mr\u00fc ve ar\u0131zalanma zaman\u0131 gibi \u00f6nemli tahminler yapman\u0131za olanak tan\u0131r.
