Recently, analysis and designing of the structures based on the Reliability theory have been the center of attention. Reason of this attention is the existence of the natural and random structural parameters such as the material specification, external loads, geometric dimensions etc. By means of the Reliability theory, uncertainties resulted from the statistical nature of the structural parame...

This thesis proposes a safety instrument system which is based on D-S evidence theory, including sensor, logic voting system and execution unit. While the logic voting system concludes the input circuit, processor, output circuit and the diagnosis module based on D-S evidence theory. According to the diagnosis module in multi-channel logic voting system and calculation based on D-S evidence the...

introduction: measuring tools in each study must be evaluated themselves. the goal of present study was designing, validating, and determining the reliability of some scales, which are used for measuring concepts of behavior change theory/models. materials & methods: this study was a descriptive one in which, at first literature review and need assessment were done. then designed tools were val...

Generalizability theory and assessment in medical training Even though it is more than 50 years old, generalizability theory, or G theory, is not well known to the medical community. It combines aspects of classic test theory and analysis of variance in order to estimate reliability (“G-study”) of a measurement instrument as a function of design aspects (“facets” in G-theory literature), and to...

In this paper, we show how a possibilistic uncertainty model can be used to represent and manipulate uncertainty about the states of a system and of its components. At the same time, we present a thorough study of the incorporation of this possibilistic uncertainty model in classical, two-state reliability theory. The possibilistic reliability of a component or system is introduced and studied....

This paper presents an original method for evaluating reliability indices for Multi-State Systems (MSSs) in the presence of aleatory and epistemic uncertainties. In many real world MSSs an insufficiency of data makes it difficult to estimate precise values for component state probabilities. The proposed approach applies the Transferable Belief Model (TBM) interpretation of the Dempster-Shafer t...

Software Quality and Reliability Prediction Using Dempster-Shafer Theory

In this article, we propose an approach to improve quality in crowdsourcing (CS) tasks using Task Completion Time (TCT) as a source of information about the reliability workers game-theoretical competitive scenario. Our is based on hypothesis that some are more risk-inclined and tend gamble with their use time when put compete other workers. This supported by our previous simulation study. We t...
