In many cases, redundant systems are beset by both independent and dependent failures. Ignoring dependent variables in MTBF evaluation of redundant systems hastens the occurrence of failure, causing it to take place before the expected time, hence decreasing safety and creating irreversible...

Purpose The purpose of this paper is to propose a procedure to construct the membership functions for a one-unit repairable system, which has both active and standby redundancy. The coverage factor is the same for the operating and standby unit failure. Design/methodology/approach The α -cut...

In this paper, we examined the reliability of Funtone software and its impact on quality service to the user. As Global System for Mobile (GSM) software is relatively new in the market and the level of awareness of its quality service is low; the need for quality assessment of these services...
