Tolerance analysis approach based on the classification of uncertainty (aleatory / epistemic)
TypeCommunications avec actes
Uncertainty is ubiquitous in tolerance analysis problem. This paper deals with tolerance analysis formulation, more particularly, with the uncertainty which is necessary to take into account into the foundation of this formulation. It presents: a brief view of the uncertainty classification: Aleatory uncertainty comes from the inherent uncertain nature and phenomena, and epistemic uncertainty comes from the lack of knowledge, a formulation of the tolerance analysis problem based on this classification, its development: Aleatory uncertainty is modeled by probability distributions while epistemic uncertainty is modeled by intervals; Monte Carlo simulation is employed for probabilistic analysis while nonlinear optimization is used for interval analysis.

DANTAN, Jean-Yves; GAYTON, Nicolas; ETIENNE, Alain; QURESHI, Ahmed Jawad; DUMAS, Antoine (AIP PRIMECA, 2012)The aim of this paper is to provide an overview of tolerance analysis. Tolerancing decisions can profoundly impact the quality and cost of product. There is a strong need for increased attention to tolerance design to ...
A statistical tolerance analysis approach for over-constrained mechanism based on optimization and Monte Carlo simulation QURESHI, Ahmed Jawad; DANTAN, Jean-Yves; SABRI, Vahid; BEAUCAIRE, Paul; GAYTON, Nicolas (Elsevier, 2012)Tolerancing decisions can profoundly impact the quality and cost of the mechanism. To evaluate the impact of tolerance on mechanism quality, designers need to simulate the influences of tolerances with respect to the ...
Management of product characteristics uncertainty based on Formal Logic and Characteristics Properties Model DANTAN, Jean-Yves; QURESHI, Ahmed Jawad; ANTOINE, Jean-François; EISENBART, Boris; BLESSING, Lucienne (Elsevier, 2013)Uncertainty in product characteristics is ubiquitous in any engineering system at all the stages of product life-cycle. Considering uncertainty from different sources during the product design phase is critical to its ...

However, it is more interesting to evaluate a predicted quality level in the design stage: ...
