Other more elaborate metrics (such as the cost elasticity of reliability or cost elasticity of life expectancy ) can be used to assess the cost-benefit aspect of adding redundancy to a system with the purpose of enhancing its reliability. We study the and metrics analytically and numerically for the partially redundant or k-out-of-n:G(F) system (or k-out-of-n system, for short). We believe the metric is a more tangible and a more cumulative measure than the metric. The expression of is dependent on component reliability or failure rate, and is highly susceptible to round-off errors to the extent that catastrophic cancellations take place. By contrast, our expression for is independent of component characteristics and is really insensitive to round-off errors since it is a purely additive formula. We provide charts for that a reliability engineer can use to assess the cost incurred in achieving a certain life expectancy for a partially redundant system. These charts are also applicable to any coherent system, since the life expectancy for a coherent system can be approximated by that of a partially redundant system.  Conference Name : The Seventh Saudi Engineering Conference in Riyadh  Publishing Year : 1428 AH 2007 AD  Number Of Pages : 12  Article Type : Article  Conference Place : Riyadh, Kingdom of Saudi Arabia  Organizing Body : The College of Engineering at King Saud University, Riyadh  Added Date : Sunday, June 19, 2011  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email علي محمد رشدي Rushdi, Ali Muhammad Investigator Doctorate arushdi@kau.edu.sa عبد العزيز عفين السلمي Alsolami, Abdulaziz Efaien Researcher Master anaawaw@gawab.com Files File Name Type Description  29857.pdf pdf ON RELIABILITY-COST CHARACTERIZATION OF A PARTIALLY REDUNDANT SYSTEM Back To Researches Page
