This paper highlights the influence of the uncertainties modeling on the results of reliability based robust design optimization. This influence is tested in three mechanical applications chosen from the literature. The results show how the robust concept of the problem is affected besides the optimization results, this reveals the necessity to choose the suitable uncertainties model before performing the optimization.
