This paper present two robust design strategies in structural system that simultaneously optimize the design goal-performance and minimize its performance variability. As a result, the maximization of a predefined goal-reliability indicator is equivalent to the optimization of the goal-performance and the performance variation concurrently. Fuzzy set theory is applied to formulate another way of dealing with such robust designs. Both single and multiple goal problems are investigated with random design variables and probabilistic constraints. This optimization approach can produce the highest goal-reliability, which is higher than that of a fixed goal-performance.
