The main aim of this paper is to define what imprecise reliability is, and discuss a variety of problems that can be solved by means of a framework of imprecise probabilities. From this point of view, various branches of reliability analysis are considered, including analysis of monotone systems, repairable systems, multi-state systems, structural reliability, software reliability, human reliab...

background: according to the measurements literature reliability of the test refers to the consistency of the test results and shows whether the obtained score is stable indication of the student’s performance in particular test reliability can be measured by different statistics formula. purpose: to determine the factors influenced the reliability of 392 mcq examinations. methods: the correlat...

separation system is one of the most important systems in rockets. the influence of this system on mission success cannot be ignored. in this paper, reliability of a sounding rocket separation system is determined using block diagram and fmea . this system is based on the flexible linear shape charge cross-section and a spring mechanism to accelerate separation. in this investigation, the relia...

It is generally accepted that performance-based design has to be reliability-based. Seismic performance evaluation is based on nonlinear dynamics and reliability theory taking into account uncertainties during analysis. Considering the economic importance of jacket type offshore platforms, the present research aims to assess the seismic performance of offshore steel platforms. In this study, th...
