用典型的三杆衍架结构设计问题，进行了结构稳健性设计与考虑不确定因素的优化设计的比较．通过用蒙特卡罗模拟法对设计结果的结构可靠性计算，表明两种设计在提高结构可靠性上是一致的，但结构稳健性设计更具有有效控制结构特性散布的优点．
With the typical design problem of three-pole truss structure, the comparison between the design of structural robustness and the optimal design considering uncertain factors is carried out. By using Monte Carlo simulations to calculate the structural reliability of the design results, it shows that the two designs are consistent in improving the structural reliability. However, the structural robustness design has the advantage of effectively controlling the dispersion of structural characteristics.
