论文摘要

在这项研究中,提出了基于实验最佳设计的多个指数,提出了一种非统计基因的多目标贪婪方法。所提出的方法同时考虑了多个集合功能,并将帕累托排名的想法应用于选择集。具体而言,迭代添加了一个新的索引,并将多目标函数评估为新集合的多目标函数。从检查的解决方案中选择了非主导的解决方案,然后考虑下一组。通过此过程,可以通过合理的计算成本进行多个集合功能的多目标优化。本文定义了一种新的贪婪算法,其中包括提出的基于非主体的多目标贪婪算法和组贪婪算法,这些算法的特征是理论上讨论的。然后,将提出的方法应用于传感器选择问题,并评估其性能。测试案例的结果表明,所提出的方法不仅给出了多目标优化问题的帕特托 - 最佳前端,而且还产生了以D-,A-和E-Overtical的方式产生的传感器集,这些传感器比仅考虑一个单个目标函数的纯贪婪方法所选择的集合优于该集合。

In this study, a nondominated-solution-based multi-objective greedy method is proposed and applied to a sensor selection problem based on the multiple indices of the optimal design of experiments. The proposed method simultaneously considers multiple set functions and applies the idea of Pareto ranking for the selection of sets. Specifically, a new index is iteratively added to the nondominated solutions of sets, and the multi-objective functions are evaluated for new sets. The nondominated solutions are selected from the examined solutions, and the next sets are then considered. With this procedure, the multi-objective optimization of multiple set functions can be conducted with reasonable computational costs. This paper defines a new class of greedy algorithms which includes the proposed nondominated-solution-based multi-objective greedy algorithm and the group greedy algorithm, and the characteristics of those algorithms are theoretically discussed. Then, the proposed method is applied to the sensor selection problem and its performance is evaluated. The results of the test case show that the proposed method not only gives the Pareto-optimal front of the multi-objective optimization problem but also produces sets of sensors in terms of D-, A-, and E-optimality, that are superior to the sets selected by pure greedy methods that consider only a single objective function.
