Publication number: 20140005816Abstract: There is a need to provide a design support system and a method thereof that extract common parts in consideration of relation to the performance. An apparatus and a method acquire common parts using multi-objective optimization. Specifically, a design support system using common parts and a method thereof include the following means. One means enters information about a shape model, an analysis condition, and an optimization condition. Another means uses multi-objective genetic algorithm to perform optimization. Still another means groups a Pareto solution as an acquired optimization result, analyzes dispersion of design variables, and associates them with a shape model. Yet another means displays common parts.Type: ApplicationFiled: June 26, 2013Publication date: January 2, 2014Inventors: Norihiko NONAKA, Ichiro NISHIGAKI
