background: simulation can be used for educating, evaluating and assessing psychometric properties of an instrument. the aim of this study was to contextualize and assess the validity and reliability of the interprofessional collaborative assessment tool (icar) in an iranian context using simulation.   methods: in this descriptive study, contextualization of the icar was assessed through severa...

In this presentation the characteristics of parameters such as loading conditions, geometrical and material properties as used for structural analysis and design are discussed. Stochastic models are shown to be most suitable for their rational representation. In particular the aspect of uncertainties and their consequences are treated. The suggested approach which combines the FE method with Mo...

In this article, reliability sampling plans are developed for the Weibull distribution when the life test is progressively first-failure censored.We use themaximum likelihoodmethod to obtain the point estimators of the model parameters. We propose an approach to establish reliability sampling plans which minimize three different objective functions under the constraint of total cost of experime...

In this paper, a more efficient approach for component-level structural reliability analysis using the First Order Reliability Method (FORM) is presented. In this approach, the continuum design sensitivity analysis (DSA) and a two-point approximation (TPA) method are employed to support the most probable point (MPP) search in the random variable space for structural reliability analysis. This a...

Reliability estimates are useful for making design decisions. We consider the case where a designer must choose between an existing component whose reliability is well-established and a new component that has an unknown reliability. This paper compares the statistical approaches for updating reliability assessments based on additional simulation or experimental data. We consider four statistica...

The lifetime of micro electro–thermo–mechanical actuators with complex electro–thermo–mechanical coupling mechanisms can be decreased significantly due to unexpected failure events. Even more serious is the fact that various failures are tightly coupled due to micro-size and multi-physics effects. Interrelation between performance and potential failures should be established to predict reliabil...

As an important tool for performance assessment in multi-state systems, the universal generating function approach is introduced and developed aiming at strength reliability analysis of structural systems. Static reliability models of statically determinate and statically indeterminate systems are built by constructing special generating functions, which are used to describe probability distrib...
