Geoffrion proper efficiency in optimization with infinitely many objectives and its applications in robust optimization(无穷多目标优化的Geoffrion真有效性及其在鲁棒优化中的应用)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2018
在多目标优化中,Pareto有效性体现了目标之间的妥协与补偿,而Geoffrion真有效性能保证补偿是有界的.本文对有无穷多个目标的优化问题引入了真有效性,完整保留了 Geoffrion的结构.基于一族锥,揭示了Geoffrion真有效性的特点及其与Pareto有效性的区别.并将Geoffrion真有效性的思想用于鲁棒优化,得到了著名的Hurwicz决策准则.

A method of two-sided matching based on multiple criteria considering disappointment and elation of both sides(考虑双方主体失望-欣喜感知的多指标双边匹配决策方法)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2018
在双边匹配研究中很少关注如何描述双方主体的失望-欣喜感知并将其引入双边匹配模型.通过对匹配主体失望-欣喜感知的刻画,提出了一种新的具有指标期望的多指标双边匹配决策方法.首先,针对具有指标期望的多指标双边匹配问题给出了数学描述;其次,匹配决策者通过对主体的指标期望值与对方主体真实值之间的比较分析,建立了双方主体的损益矩阵;然后,依据失望理论,构建双方主体在各指标下的感知效用矩阵,并集结得到双方主体的综合感知效用矩阵;进一步构建以双方主体可接受最低水平为约束,双方主体综合感知效用最大为目标的多目标优化模型 ...
