A New Multidisciplinary Design Optimization Method Accounting for Discrete and Continuous Variables under Aleatory and Epistemic Uncertainties
Various uncertainties are inevitable in complex engineered systems and must be carefully treated in design activities. Reliability-Based Multidisciplinary Design Optimization (RBMDO) has been receiving increasing attention in the past decades to facilitate designing fully coupled systems but also achieving a desired reliability considering uncertainty. In this paper, a new formulation of multid...
متن کاملDesign Optimization With Discrete and Continuous Variables of Aleatory and Epistemic Uncertainties
Reliability based design optimization has received increasing attention for satisfying high requirements on reliability and safety in structure design. However, in practical engineering design, there are both continuous and discrete design variables. Moreover, both aleatory uncertainty and epistemic uncertainty may associate with design variables. This paper proposes the formulation of random/f...
متن کاملInclusion of Aleatory and Epistemic Uncertainty in Design Optimization
1. Abstract This paper presents a design optimization methodology under three sources of uncertainty: physical variability (aleatory); data uncertainty (epistemic) due to sparse or imprecise data; and model uncertainty (epistemic) due to modeling errors/approximations. A likelihood-based method is use to fuse multiple formats of information, and a non-parametric probability density function (PD...
متن کاملA heuristic method for combined optimization of layout design and cluster configuration in continuous productions
Facility layout problems have been generally solved either hierarchically or integrated into other phases of plant design. In this paper, a hybrid method is introduced so that clustering and facilities layout can be simultaneously optimized. Each cluster is formed by a group of connected facilities and selection of the most appropriate cluster configuration is aimed. Since exact method by MIP i...
متن کاملEpistemic versus Aleatory Judgment Under Uncertainty
Both cases involve judgment under uncertainty, with a mixture of evidence supporting and opposing each event’s likelihood. Yet, they involve what appears to be two qualitatively distinct representations of uncertainty. In the first case, Allie’s uncertainty reflects the unpredictability inherent to a stochastic process (i.e., random draws from the pool of Bingo numbers). This type of uncertaint...
