Phased-mission system (PMS) usually has the characteristic of high complexity and integration and operates under a complex condition, so system reliability plays an important role during its mission. The common cause failure (CCF) in system which can destroy the hypothesis that the failures are independent, especially in the PMS. Based on their impacts on the components, CCFs can be classified into...
Solar systems are highly penetrating into the electrical networks all over the world currently. Solar radiation is not steady and never will be, and so, a storage system is required to ensure a stable and continuous supply. To increase the reliability of the system whether islanded or network connected, it is better to have a storage system. After all, the decision of whether to use a storage system...
This paper discusses a method used for the systematic improvement of NASA's Lunar Surface Systems avionics architectures in the area of reliability and fault-tolerance. This approach utilizes an integrated system model to determine the effects of component failure on the system's ability to provide critical functions. A Markov model of the potential degraded system modes is created to characterize...
Traditional approaches to handling functional dependence in systems with imperfect fault coverage are based on Markov models, which are inefficient due to the well-known state space explosion problem. Also, the Markov-based methods typically assume exponential time-to-failure distributions for the system components. In this paper we propose a new combinatorial approach to handling functional dependence...
We present a two-level random telegraph noise (RTN) characterization technique which allows the estimation of RTN model parameters with statistical validity, thus acquiring a deeper insight into the physics of noise-generating process. A two-state Markov chain is used to model the stochastic behavior of RTN. In this way, an easy implementation of Monte Carlo performance and reliability simulations...
The traditional approach to handling functional dependence loops is based on Markov models, which are inefficient due to the well-known state space explosion problem. This paper proposes a new and efficient approach to handling functional dependence loops in the system reliability analysis. Based on the divide-and-conquer strategy, the approach transforms a system with functional dependence loops...
In order to enhance both dependability and security which are two aspects of relaying system, self-checking and monitoring facilities are usually considered along with routine test. In practice, back-up relay can has mal trip when not required and may fail to trip when required which may cause power system blackout due to cascading failure. Generally, this situation is not taken into account in the...
This paper presents a novel and simple approach to reliability analysis of phased-mission systems. The technique presented in this paper transforms a phased-mission system into several non-phased-mission systems, and thus allows each phase to be modeled separately. The mission succeeds as long as every phase successively executes its requirements, and failed component(s) of any phase is(are) repaired...
