摘要
基于灵敏稳健性设计思想,定义了单目标优化时的单目标损失量和多目标优化问题中的目标总损失量;继而对基于重要度的损失权重系数确定方法进行详细研究,并提出了基于目标总损失量择优的有限解集多目标决策方法,旨在选择候选解集中受不确定因素和设计变量误差的影响最小、敏感性最低的Pareto解为最终方案;最后以卫星附件控制系统为例进行仿真,充分验证了此方法的有效性和可行性。
On the basis of sensitivity robust design, the single object-value loss for single-object optimization and overall object-value loss for multi-objective optimization were investigated in detail. And a new method for ascertaining loss weight coefficients was proposed and the lnfinite Sets Multi-objective Decision-Making Method based on overall object-value loss （1SMDMM） was put forward to choose the final scheme with high robustness owing to design deviations and unexpected factors. Finally, the four-objective optimizer and decision-making of a satellite with flexible appendage were analyzed, proving its validity and adaptability of ISMDMM in most engineering problems.
