In structural reliability analysis, simulation methods are widely used. The statistical characteristics of failure probability estimate these have been well investigated. this study, the sensitivities and its with regard to sample, called ‘contribution indexes’, proposed measure contribution sample. indexes in four methods, i.e., Monte Carlo (MCS), importance sampling (IS), line (LS) subset (SS...

Abstract Second-order reliability methods are commonly used for the computation of reliability, defined as probability satisfying an intended function in presence uncertainties. These can achieve highly accurate predictions owing to a second-order approximation limit-state around Most Probable Point failure. Although numerous formulations have been developed, lack full-scale comparative studies...

A framework supporting fast prototyping as well as tuning of distributed applications is presented. The approach is based on the adoption of a formal model that is used to describe the orchestration of distributed applications. The formal model (Orc by Misra and Cook) can be used to support semi-formal reasoning about the applications at hand. The paper describes how the framework can be used t...
