High demands on advanced safety and driving functions, such as active safety and lane departure warnings, increase a vehicle’s dependency on automotive electrical/electronic architectures. Hard real-time requirements and high reliability constraints must be satisfied for the correct functioning of these safety-critical features, which can be achieved by using the AUTOSAR (Automotive Open System...

We study the reliability and sensitivity analysis of a system with M operating machines, S warm standbys, and a repairable service station. Failure times and service times of each machine (operating or standby) are assumed to be exponentially distributed. While the service station is working, it is subject to breakdowns according to a Poisson process. When the station breaks down, it requires ...

By using the Markov process, system state transitions can be modelled to predict the system availability in many realistic applications, wherein all components of the system cannot be treated as identical because of their failure and repair characteristics. In this paper, efforts have been made to examine the availability characteristics for three different configurations with warm standby, swi...

Here we examine an active redundant system with scheduled starting times of the units. We assume availability of n non-identical, non-repairable units for replacement or support. The original unit starts its operation at time s1 = 0 and each one of the (n 1) standbys starts its operation at scheduled time si (i = 2, . . .,n) and works in parallel with those already introduced and not failed bef...
