A simple and effective method of assessing the reliability of a piece of software is to plot the cumulative number of failures observed during testing, N(x), against time x. Since no software is ever completely free of errors, be it careless minor oversights or the results of serious design...

Many existing works on multi-level time sharing policies have assumed infinitely small quanta, infinite levels or exponential service time distributions. In this paper, we investigate the performance of a multi-level time sharing policy under heavy-tailed workloads under finite levels when...
