Mechatronic layout strategies became shorter and extra parallelized, brought about through becoming time-to-market strain. tools that let quantitative research in early layout phases are required, should still dependability analyses target to steer the layout. as a result restricted quantity of knowledge during this section, the extent of uncertainty is excessive and specific modeling of those uncertainties turns into necessary.
This paintings introduces new uncertainty-preserving dependability tools for early layout levels. those contain the propagation of uncertainty via dependability types, the activation of knowledge from comparable elements for analyses and the mixing of doubtful dependability predictions into an optimization framework. it truly is proven that Dempster-Shafer concept should be a substitute for likelihood concept in early layout degree dependability predictions. specialist estimates will be represented, enter uncertainty is propagated in the course of the method and prediction uncertainty could be measured and interpreted. The ensuing coherent technique could be utilized to symbolize the uncertainty in dependability models.
