Therefore, the aforementioned three approaches are not ideal for addressing the design engineer’s key question; how should the design be changed to improve robustness and failure rates. The present study builds upon the existing robust and reliability-based design optimization ( R 2 BDO...

Verification of the results by comparison to commonly used installation strategies shows its quality excellence. In the present work, classical heuristic optimization algorithms (e.g., genetic algorithm or simulated...

Tolerances are, therefore, allocated to each part of the mechanism in purpose to obtain an optimal quality of the final product. Three main issues are generally defined to realize the tolerance analysis of a mechanical assembly...
