المستخلص:

          في هذا البحث , استعملنا طرائق مختلفة لتقدير معلمة القياس للتوزيع الاسي كمقدر الإمكان الأعظم ومقدر العزوم ومقدر بيز في ستة أنواع مختلفة عندما يكون التوزيع الأولي لمعلمة القياس : توزيع لافي  (Levy) وتوزيع كامبل من النوع الثاني وتوزيع معكوس مربع كاي وتوزيع معكوس كاما وتوزيع غير الملائم (Improper) وتوزيع Non-informative. وفقا لدالتي الخسارة هي : دالة الخسارة التربيعية و دالة الخسارة التربيعية الموزونة. استعمل أسلوب المحاكاة في مقارنة اداء كل مقدر, بافتراض عدة حالات لمعلمة التوزيع الاسي استعملت لتوليد البيانات ولأحجام مختلفة من العينات ( صغيرة , متوسطة , كبيرة). وقد أظهرت نتائج المحاكاة بان طريقة بيز الأفضل وفقا لمقياس اقل قيمة متوسط مربع الأخطاء (MSE) , متوسط مربع الأخطاء الموزونة (MWSE) مقارنة بطريقتي الإمكان الأعظم (MLE)  وطريقة العزوم (ME) . وفقا للنتائج المستحصلة , نرى بانه عندما يكون التوزيع الاولي لـ توزيع معكوس كاما عند قيم معينة لمعلمتي التوزيع الاولي , أعطى نتائج أفضل وفقا لاقل قيمة لـ MSE ولـ MWSE مقارنة بنفس القيم المستحصلة بطريقتي MLE و ME,عندما تكون القيمة الحقيقة المفترضة لـ ولكل حجوم العينات (n). وعندما يكون التوزيع الاولي لـ هو غير الملائم  (Improper) عند قيم معينة لمعلمتي التوزيع الاولي, اعطى نتائج أفضل وفقا لاقل قيمة لـ MSE  ولـ MWSE مقارنة بنفس القيم المستحصلة بطريقتي MLE و ME, للقيم الحقيقة المفترضة لـ ولكل حجوم العينات (n) .

...Show More Authors
Abstract<p>The research presents the reliability. It is defined as the probability of accomplishing any part of the system within a specified time and under the same circumstances. On the theoretical side, the reliability, the reliability function, and the cumulative function of failure are studied within the one-parameter Raleigh distribution. This research aims to discover many factors that are missed the reliability evaluation which causes constant interruptions of the machines in addition to the problems of data. The problem of the research is that there are many methods for estimating the reliability function but no one has suitable qualifications for most of these methods in the data such </p> ... Show More
