The issue of navy vessel's overall system and life-cycle effectiveness-cost analysis is presented. The life-cycle's composition of navy vessel and the procedures of effectiveness-cost analysis are explored, and the difficulties of overall effectiveness-cost analysis aimed at whole life cycle are analyzed. On this basis, the simplification rules of effectiveness and cost are proposed respectively....
In this paper an authentication protocol, Kerberos, is investigated. To consider the scenario where there are multiple realms, a simplification is applied. The simplified model is equivalent to original model in terms of the steady state distribution. It is analysed numerically using a fluid flow approximation and is verified by stochastic simulation.
For a dynamic fault tree (DFT) that models dynamic system, the occurrence of top event depends on not only the combination of basic events, but also on the occurrence order of basic events. Cut sequence is a set of basic events that fail in a particular order that can induce top event. Cut sequence set (CSS) model uses cut sequences to analyze the dynamic behaviors of dynamic systems, and if includes...
