摘要
稳健优化设计中存在多个设计目标,以及目标最优和目标波动需要同时满足的多目标问题,由于量纲和数量级的差异,无法用简单的加权组合来获得全局最优解。介绍了基于模糊数学的稳健优化设计方法,利用隶属函数和贴近度,得到满意的全局最优解,并且通过实例证明了该方法的有效性。
Inside optimal steady design there exists multi-objective problems with the multi-objective of design and with the need of simultaneous satisfaction of objective optimization and objective fluctuation global optimal solution method can not be obtained by simple weighted combination owing to the difference of dimension and order of magnitude.The steady optimal designing method is introduced basing on fuzzy mathematics.The satisfactory global optimal solution is obtained by the use of subordinative function and degree of close up and the effectiveness of this method is verified by means of a living example.
