The reliability behaviour of systems under changeable load is studied in the paper. A case when the load changes continuously in time is considered, i.e., a continuous extension of the discrete load-share reliability models is proposed. The main assumption used in the paper is the so-called...

Component failure in large-scale IT installations such as cluster supercomputers or internet service providers is becoming an ever larger problem as the number of processors, memory chips and disks in a single cluster approaches a million. In this paper, we present and analyze field-gathered...

Abstract. The paper presents a model of multistage degraded system subject to L random failure modes and partial repairs. A transient analysis is performed and transient probabilities are calculated to find the availability, the mean of life times and of operational life times. Constant state...
