چکیده
در این مقاله، به مقایسۀ تصادفی افزونگی فعال در سطح مؤلفه، در مقابل به سطح سیستم می‌پردازیم. هم‌چنین به مقایسۀ تصادفی طول عمر سیستم‌های سری با استفاده از ترتیب‌های تصادفی معمولی، نرخ خطر و نرخ خطر معکوس در دو حالت‌ (الف) مؤلفه‌های یدکی و اصلی هم توزیع و مستقل و (ب) مؤلفه‌های یدکی و اصلی غیر هم توزیع و وابسته، می‌پردازیم.

چکیده English

In this paper, we discuss stochastic comparisons of active redundancy at component level versus system level. We also consider series systems in order to compare their lifetimes using the usual stochastic, the hazard rate and the reversed hazard rate orders, for two cases: (i) the spare and parent components are independent and have the same distribution, and then (ii) the spare and parent components are dependent and have not the same distribution. ./files/site1/files/72/6Abstract.pdf
