The reliability of software is one of the most important software metrics. In the course of time, systems have become more and more complex and that is why software has become more complex, too. It is an undeniable fact that this will lead to an increasing number of software faults. Models of software reliability are used to track down software faults. The aim is to make sure that an improvemen...

Recent investigations into resilience of large-scale highperformance computing (HPC) systems showed a continuous trend of decreasing reliability and availability. Newly installed systems have a lower mean-time to failure (MTTF) and a higher mean-time to recover (MTTR) than their predecessors. Modular redundancy is being used in many mission critical systems today to provide for resilience, such...

In recent times in the business of semiconductor testing, the claim has been that Test Cost has begun to dominate the overall cost of product (die + packaging + test) in some product lines. The cost models that I have seen are simplistic models that just take into account the product yield and the per-second test cost. More recently, I have become even more concerned over the effects of Mean-Ti...

Due to the expected increase of defects in circuits based on deep submicron technologies, reliability has become an important design criterion. Although different approaches have been developed to estimate reliability in digital circuits and some measuring concepts have been separately presented to reveal the quality of analog circuit reliability in the literature, there is a gap to estimate re...

In order to solve the problem that online upgrade system for vehicle ECU (Electronic Control Unit) has poor reliability and stability, this paper presents a reliability assessment model based on Markov mathematical model. According to the practical operation of online upgrade system, this paper divided the work state of the system into eight kinds such: normal running state, equipment failure s...

An accurate estimate of host reliability is important for correct analysis of many fault-tolerance and replication mechanisms. In a previous study, we estimated host system reliability by querying a large number of hosts to find how long they had been functioning, estimating the mean timeto-failure (MTTF) and availability from those measures, and in turn deriving an estimate of the mean time-to...
