... for the reliability analysis and design of the L-PBF process. The method determines a feasible region of the design space for given design requirements at specified reliability levels. If a design point falls into the feasible region, the design requirement will be satisfied with a probability higher or equal...

..., unnecessarily high costs can be incurred due to unexpected equipment failure (lack of maintenance) or excessive maintenance. In this paper, a reliability-based dynamic maintenance threshold (DMT) is calculated based on the updated equipment status. The benefits of the DMT are demonstrated in a numerical case...

... to constant BHF. Extensive research has been carried out in the past to determine this optimal profile. However, these deterministic efforts neglect the sensitivity of this optimal BHF design to unintended process variations inherent in sheet forming. This paper investigates the reliability of optimal...
