Multi-objective Robust Design Optimisation using Hierarchical Asynchronous Parallel Asynchronous Evolutionary Algorithms
Lee, Dong-Seop, Gonzalez, Luis F., Srinivas, K., & Periaux, Jacques (2005) Multi-objective Robust Design Optimisation using Hierarchical Asynchronous Parallel Asynchronous Evolutionary Algorithms. In 45th AIAA Aerospace Sciences Meeting and Exhibit, 8 - 11 Jan 2007, Reno, Nevada.
In this paper, a new Robust Design method is investigated with a hierarchical asynchronous parallel Multi-objective evolutionary optimisation framework to overcome single and multi-point design optimisation problems in Aerodynamics. The single design techniques produce solutions that perform well for the selected design point but have poor off-design performance. Here, we show how the approach can provide robust solutions using game theory in the sense that the solutions are as less insensitive to little changes of the input parameters. Starting from a statistical definition of stability, the method finds, simultaneously Pareto non-dominated solutions for performance and stability which offer alternative choices to the designer.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
